In recent years , with the strengthening of our country ' s sewage treatment and the steady growth of municipal sewage treatment scale , our country has become a big country of sewage treatment . As a by - product of sewage treatment , our country has enacted a series of national policies and industry standards , and has made clear regulations and requirements for sludge treatment . With the development of policies and high growth factors , the disposal industry of sludge treatment is expected to break through the bottleneck period and drive into the fast lane . As the policy is good and the high growth factor drives , the sewage treatment capacity is 13,87.2 million tons / day by the end of 2014 , which is nearly 5.1 % higher than that in 2013 .

The amount of sewage treatment increases year after year, and sludge, as a by-product of sewage treatment, increases with it. By the end of 2014, the amount of municipal sewage treatment in China will reach 38.27239 billion tons, while the production of municipal wet sludge will reach 21.43 million tons (conservative estimate). According to 10,000 tons of sewage produced 5.6 tons of wet sludge calculation.

In 2015, the environmental protection industry in the "new normal", China has successively promulgated a series of national policies and industry standards, including "water ten > clear the existing sludge disposal facilities should be basically completed before the end of 2017 standard transformation, prefecture level and above city sludge harmless disposal rate should be before the end of 2020 of more than 90%. With the drive of favorable policies and high growth factors, sludge treatment and disposal industry is expected to break through the bottleneck, into the fast lane.

Driven by marketization, more and more environmental protection enterprises begin to lay out the sludge disposal market. According to industry research data, investment and operation enterprises in the sludge treatment and disposal market in China participate in scattered projects. By the end of 2015, the scale of sludge disposal had reached 7.97 million tons per year (dry mud, an increase of 185.66% compared with 2010), from a regional perspective, Guangdong, Jiangsu, Zhejiang, Hebei, Henan, Hunan, Shandong, Beijing and other regions have built large scale, accounting for 53.51% of the national new scale, which is the key province and city of sludge project bidding in the next few years.

In recent years, the macroeconomic volatility, the traditional enterprise growth slowed, press industry demand will be affected by a certain impact, although the traditional application field widely, but growth has slowed down. The field of environmental protection is the most promising future market of filter press filter press used in industry, urban sewage sludge, industrial wastewater sludge, tap water sludge and sludge treatment, sludge reduction equipment is the most economical and effective sludge treatment, the current state of attention, the press industry demand increased rapidly, the current press leading enterprises in the field of environmental protection, for the basic product sales of more than 50%, sludge treatment has become a new engine of development of filter press industry.

Environmental protection, energy saving and emission reduction policy requirements

Filter press was used in chemical industry at the beginning of the 18th century, and is still widely used in chemical, pharmaceutical, metallurgical, dyestuff, food, brewing, ceramics and environmental protection industries. The state has higher and higher requirements for environmental protection and utilization of resources in various industries. The environmental protection requirements for sludge, waste water and waste residue are raised, and energy saving, emission reduction, cleaner production, green manufacturing are vigorously advocated. Filter press with good filtration effect becomes an inevitable choice.

At present, our country attaches great importance to the sewage treatment industry. In China, there is a upsurge in the construction of sewage treatment plants. Various places have begun to build sewage treatment plants one after another, and the filter press is the infrastructure of the sewage treatment plants, so the sewage treatment plants, Industrial and mining enterprises will increase the new demand for filter press.

On 26 November 2010, the Ministry of Environmental Protection issued a circular requiring that "sewage treatment plants that do not currently have sludge treatment capacity shall complete and operate sludge treatment facilities within two years from the date of the issuance of the notice;" For the purpose of storage, sludge must be dewatered to less than 50% water content in sewage treatment plant. In the existing sludge treatment dewatering system, the new standard of moisture content can be reached only by membrane filter.

The implementation of the new environmental protection law in 2015 and the promulgation of the "Ten articles of Water" are more favorable to the water treatment industry than ever before, and the sludge, as a product of sewage treatment, is also concerned. As an important equipment for sewage sludge treatment, the filter press has a very broad development space.

In addition, the transformation of economic growth mode and the policy guidance of energy saving and emission reduction will form the external booster force for enterprises to choose filter press, will further develop the emerging market of filter press, and promote the rapid release of the existing market of filter press.

Development trend of Resource Deep processing

In the future, the development trend of deep processing and the increasing demand of enterprises for economic benefit will be more and more. First, the development trend of industrial refinement will form a new domain of filter press ownership, and secondly, the demand for increasing output rate will also promote the increase in the use of filter press. Due to the rising price of upstream raw materials, some enterprises use filter press because of the demand for higher production rate of their products. In addition, the good filtering effect of the filter press will reduce the cost of the next production process. Enterprise cost control requirements will also promote the use of filter press.

Substitution of domestic enterprises to international rivals

After a long period of technical research and development, domestic filter press enterprises gradually reduced or reached the performance of foreign filter press products, making domestic customers abandon the original high international filter press products and buy domestic filter press products instead. Improved its competitiveness in the international market, filter press exports increased year by year.

In recent years, domestic filter press enterprises through the introduction, digestion, innovation and independent innovation, rapid progress in manufacturing technology, product technology and quality significantly improved, industry backbone filter press enterprises have mastered PLC automatic control, automatic diaphragm press, Automatic water washing of filter cloth, automatic unloading of cake, automatic transfer of liquid, and other automatic technologies. The gap with foreign countries is getting smaller and smaller. The manufacturing level of large and medium-sized filter presses and filter plates in key enterprises is close to or up to the international advanced level. The cost advantages of domestic filter presses are obvious. While gradually entering the international market, import substitution has been partially realized. In recent years, the number of filter press imported in China is decreasing year by year.

The market prospect of filter press in golden period is promising.

Filter press is one of the traditional solid-liquid separation equipment. As early as more than 100 BC, Liu An, king of Huainan in China, invented the application of the most primitive filter press in the process of making tofu. More than 30 years since the reform and opening up, the filter press has been used in the material of filter plate. Structural form, high efficiency filtration medium, separation efficiency, automation level, function integration, product quality and reliability have developed rapidly, and the gap between product performance and product performance in developed countries in Europe has become smaller and smaller, especially in the past five years. The success of research and development of high pressure membrane filter press makes the production of filter press in our country rank first in the world. The country vigorously advocates energy saving, emission reduction, clean production, green manufacturing. Filter press is the main equipment used in the field of environmental protection application, chemical industry. Market demand for major industrial equipment and reprocessing equipment in metallurgical, coal and food industries is expected to increase substantially.

With the increasing demands of society on environmental protection and the development of industry towards a new type of industrialization, the application of filter press in sludge treatment, mineral processing and chemical processing has been continuously expanded. The domestic filter press is expected to have a high performance-price ratio. Is gradually winning the favor of the international market, domestic filter press and filter plate to export to South America, North America, Southeast Asia, the Middle East, Europe and other places.

Driven by market demand and national policy, we can see that the market prospect of filter press industry is very promising. The market space of filter press industry in China is huge, and the market demand of filter press industry in China will reach 100 ~ 130 billion yuan in 2015.
