New Technology: Filter Press Manufacturing Technology To Solve The Problem Of Sludge Treatment

The surge of sludge disposal market has widened the development space of filter press manufacturers, and expanded production capacity and improved R & D capability has become the focus of development of such enterprises.

　　 Zhong Da Peng The high pressure deep dehydration technology developed by Foshan Jin Kai Di filtration equipment Co., Ltd. (hereinafter referred to as golden Kaidi) can effectively reduce the moisture content of sludge treatment, reduce the environmental cost of enterprises, and improve the utilization rate of sludge resources.

According to statistics of China's sludge treatment and disposal in-depth investigation and investment strategic planning analysis report from 2013 to 2017, there were more than 2500 urban sewage treatment plants in China in 2010, and the urban sewage treatment capacity has reached 1.22 million tons per day. But at the same time, a large amount of excess sludge has been generated. With the water cut rate of 80%, the total annual output of sludge will soon exceed 30 million tons, and the situation of sludge disposal is grim.

In the next few years, it is predicted that the sludge disposal market will break out in the next few years. It is estimated that the market size of sludge disposal in the next five years will reach about 1000 billion tons.

Be relative to increasingly The expansion of the market scale, China's current specialized sludge disposal enterprises are not large, small scale, weak strength of the industry development problem is outstanding. Relative to more than 75% of the urban sewage treatment rate, the current domestic harmless disposal rate of sludge is less than 35%, and the development level is lagging behind.

In the sludge treatment method, sludge mechanical dewatering is effective to reduce the volume of sludge treatment and improve the reuse rate. After dewatering, the sludge can be disposed through land use, sanitary landfill, building materials utilization and drying and incineration.

Water content is an important index of the degree of sludge treatment. "Moisture content directly affects the difficulty of transportation and late disposal of enterprises, and the sludge with high moisture content is prone to produce odor, seepage fluid and so on, resulting in two pollution." Insiders said.

The moisture content of mud cake produced by the traditional sludge dewatering technology is about 80%, while the moisture content of mud cake produced by conventional deep sludge dewatering technology and ultra high pressure deep dehydration technology is 80% and 40-45% respectively, and compared with traditional technology, the investment and operation cost of ultra high pressure deep dehydration technology are lower.

"Industrial sludge will normally be delivered to a qualified third party company after dehydration for later treatment. The transportation cost will be calculated according to the weight of the mud cake, and the annual output of 1 million tons of sludge will be calculated. The mud cake with a water content of 45% is less than 80% of the mud cake, and the transportation cost can be reduced by three times. The follow-up volume is 3 times lower than that of the landfill, while the leachate produced after landfill is reduced by over 50%, which greatly reduces the pollution produced by the later treatment." Pang Zhongda said.

The high dry dewatering special pressure filter and high pressure and high efficiency filter press developed by kincaidi are ultra high pressure deep dehydration technology, which mainly serves industries such as printing and dyeing, papermaking, leather, ceramics, municipal sewage and so on. "With the improvement of environmental protection requirements, the demand for sludge management will increase with the increase of ceramic and printing and dyeing enterprises. The sludge market in Foshan is huge." Pang Zhongda said that at present, Kim Kay has provided equipment and services for a number of related enterprises in Foshan, and has established a sludge treatment center with qualified third party companies.

In 2012, Foshan golden Kaidi filtration equipment Co., Ltd. was identified as a national high and new technology enterprise. Its super filter used in R & D was applied to the super filtration plant. high pressure Technology is superior to other technologies in terms of energy saving and environmental protection.

Guangdong, even Southern China, has not yet had the same strength as Kim Kai Di in the field of sludge treatment equipment technology. Last year, the company's annual output value was nearly 80 million yuan, and Pang Zhongda's goal was to produce 500 million yuan in five years.

The premise of increasing output value is the expansion of production capacity. According to Pang Zhongda, Kim Kaiji will be in Zhejiang Tiantai County in March next year to establish an area of 60 mu of the workshop, "later Foshan company will be the company's technical research and development center, specially for the filter press production technology to provide intellectual services." Pang Zhongda said.

At present, Kim Kai Di has 12 professionals in the environmental protection industry for many years, and has worked with Zhongshan University, South China University of Technology, Guangdong University of Technology and other universities for a long time, and has core independent intellectual property rights. Up to 63 patents have been accumulated for invention and utility models, among which 2 are international specialties, and sludge deep dehydration engineering equipment and pre-treatment technology are at the leading level in China.

There are many talents in the Pearl River Delta region, which are rich in the market of sewage sludge, which is conducive to the development of technology research and development, while the main production is in Zhejiang.
