"the annual output of wet sludge will reach about 35 million tons in 2015. ” "Zhang Yi, president of Shanghai Environmental Institute, published on August 29," prospects for the Future decade of solid waste Segmentation in China ", a set of data has attracted the attention of Pang Zhongda.

The rapid increase of sludge disposal market has widened the development space of filter press manufacturing enterprises, expanded production capacity and improved R & D capability.

The ultra-high pressure deep dehydration technology developed by Foshan Jinkedi Filtration equipment Co., Ltd. (hereinafter referred to as Jinkedi), where Pang Zhongda belongs, can effectively reduce the moisture content of sludge treatment and reduce the environmental protection costs of enterprises. Improve the reuse rate of sludge resources.

Sludge disposal market will soar

     According to the "report on the depth investigation and Investment Strategic Planning of sludge disposal in China 2013-2017" statistics, in 2010, more than 2500 municipal sewage treatment plants in China have been built, and the urban sewage treatment capacity has reached 122 million tons per day. But at the same time, a large amount of excess sludge was produced. With the calculation of moisture content of 80%, the annual total water production of sludge in China will soon exceed 30 million tons, and the situation of sludge treatment is grim.

In the next few years, it is predicted that the sludge disposal market will break out, and the market size of sludge disposal may reach about 100 billion tons in five years.

Compared with the expanding market scale, there are not many enterprises specialized in sludge disposal in our country at present. Compared with more than 75% of the municipal sewage treatment rate, the domestic sludge disposal rate is less than 35%, and the development level is backward.

In the sludge treatment method , the sludge treatment method is adopted to reduce the volume of the sludge treatment , the utilization rate of the sludge is improved , the sludge mechanical dewatering function is obvious , and the sludge can be treated by land use , sanitary landfill , building material utilization and dry burning after being dehydrated .

EHV treatment Technology helps to protect Environment

Moisture content is an important index of sludge treatment degree. "moisture content directly affects the difficulty of enterprise transportation and later disposal, and sludge with high moisture content is prone to produce foul smell, osmotic liquid and so on, causing secondary pollution," the industry said.

The water content of mud cake produced by traditional sludge dewatering technology is about 80%, while that produced by conventional deep sludge dewatering technology and ultra-high pressure deep dewatering technology is 80% and 40-45%, respectively. The equipment investment and operation cost of UHP deep dehydration technology is lower.

"Industrial sludge is usually handed over to a qualified third party company for post-treatment after dewatering. The cost of transportation is calculated on the basis of the weight of the mud cake, calculated on the basis of 1 million tons of sludge produced annually by the enterprise, and the sludge cake with 45% moisture content is more than 80% mud cake. Transportation costs have been reduced threefold, subsequent treatments such as the overall volume of landfills have been reduced by three times, and leachate produced by landfill has been reduced by more than 50 per cent, greatly reducing the pollution generated by post-treatment, "said Pang Chung-da.

The special filter press for high dryness dehydration and the high pressure and high efficiency filter press developed and manufactured by Kim Keti apply the ultra-high pressure deep dehydration technology, which mainly serves the industries of printing and dyeing, papermaking, leather, ceramics, municipal sewage, etc. "with the improvement of environmental protection requirements, The demand of enterprises for sludge treatment will rise with the increase. Foshan, where there are many ceramic, printing and dyeing enterprises, the sludge market is very large. "Pang Zhongda said, at present, Jinkai provides equipment and services to many related enterprises in Foshan. More with qualified third-party companies to establish sludge treatment center.

Trend

Foshan will become the technology export center of filtration equipment

In 2012, Foshan Jinkedi Filtration equipment Co., Ltd. was recognized as the national high-tech enterprise. The ultra-high voltage technology used in the filter press developed and manufactured is superior to other technologies in energy saving and environmental protection.

Guangdong, and even South China, do not yet have an equivalent in the technical field of sludge treatment equipment. Last year, the company's annual output value was nearly 80 million yuan, while Pang Zhongda's target was 500 million yuan in five years.

The premise of the increase in output value is the expansion of production capacity. According to Pang Zhongda, Jin Kaidi will set up a 60-acre plant in Tiantai County, Zhejiang Province, in March next year. "Foshan Company will be the technology research and development center of the company in the future," he said. It is specialized in providing intellectual services for filter press production technology, "Pang Zhongda said.

Kincaid, currently has engaged in environmental protection industry for many years of professional personnel 12 people, and long-term with the Zhongshan University, South China University of Technology and Guangdong University of Technology and other colleges and universities and R & D cooperation, has the core of independent intellectual property rights, a total of invention and utility model patents as high as 63, in which the international patent 2, sludge dewatering engineering equipment and processing technology in the domestic leading level.

There are many talents in the Pearl River Delta area, which are abundant in the market of sludge, which is helpful for the development of technology research and development. The main production is located in Zhejiang.
