“Bio Leaching Technology†Sludge Deep Dewatering and Drying Project was officially put into use
China Drying Network News Lu Village Sewage Treatment Plant “Bio Leaching Technology†Sludge Deep Dewatering and Drying , “Chemical Conditioning Technology†Sludge Deep Dewatering Unit Project was officially put into use, Lu Village, Taihu New City, Chengbei Sewage Treatment Plant About 500 tons of sludge produced are safely disposed of, benefiting approximately 2.2 million people in the main city. The two projects used the "Bio Leaching Technology" of Nanjing Agricultural University and the "Chemical Conditioning Technology" of Tongji University. Both technologies are leading domestically. The difference is that the former is mainly treated by microorganisms, and the mud blocks formed are completely organic substances, which can be used for greening nutritious soils and organic fertilizers, and the latter are mainly treated with chemical agents, and the formed mud blocks can be used as sintered porous bricks. Domestic waste is buried in the soil, cement cement aggregates and sludge incineration plant raw materials, etc. In fact, the safe disposal of sludge has been plaguing many cities in China and is an important problem in the management of water environment. Sludge disposal is not good, and the existing wastewater treatment results will also be greatly reduced. The treatment capacity of Lucun sewage treatment plant in the two major projects is 200 tons/day and 210 tons/day respectively, and the emergency disposal scale is 260 tons/day and 280 tons/day respectively, which can fully meet the sludge treatment requirements of the three major wastewater treatment plants in the main urban area. . The commissioning of the project means that sludge from the treatment of more than 500,000 tons of domestic sewage in the main urban area will be safely handled. The mud cake with a water content of only 55% will not only be reduced by half in volume, but also stable and harmless. Use resources. News link: Sludge dehydration drying and volume reduction are both an important part of the sludge treatment process and one of the most difficult to achieve. The method of mechanical dewatering in the domestic sewage treatment plant usually can only reduce the moisture content of the sludge to about 80%, and a large amount of water brings about difficulties for subsequent treatment of the sludge. If water is removed by heating and evaporating, the huge energy consumption will make the sludge treatment cost high. Sludge dewatering and volume loss reduction are difficult because the sludge obtained during the sewage treatment process has high hydrophilicity, which makes it difficult for the water in the sludge to be liquid to be separated at a low cost and high efficiency, resulting in dewatering. It is difficult for mud to realize the unified disposal goals of economic and environmental protection.
