The sludge filter press is not completely dehydrated, and the treated sludge is not formed and has viscosity; the moisture content of the treated sludge is much higher than 60%, the environmental protection is not up to standard, and the accumulation will still contaminate the soil;
At present, many industrial enterprises and sewage treatment plants in China have sludge dewatering equipment, such as plate and frame filter press, belt filter press, chamber filter press, diaphragm filter press and other sludge filter presses, but still prepare Troubled by sludge dewatering. The situation is as follows:
The sludge filter press is not completely dehydrated, and the treated sludge is not formed and has viscosity;
The treated water content of the sludge is much higher than 60%, the environmental protection is not up to standard, and the accumulation will still contaminate the soil;
The sludge reduction is not enough. The production of mud cake is large, the floor space is large, and the mud cake transportation volume is increased;
Sludge dewatering efficiency is too low. For a typical batch-operated sludge filter press, one treatment cycle is as short as one or two hours. If you want to reduce the moisture content of the cake a little, it takes four or five hours.
What kind of sludge dewatering equipment can be selected to get rid of sludge dehydration?
Sludge deep dewatering equipment!
Take the Dingsheng sludge dryer, this sludge deep dewatering equipment is an example:
After sludge treatment, it is formed into a dry hard mud cake without stickiness;
The treated municipal sludge has a moisture content of less than 60%, and the industrial sludge has a moisture content of 15%-55%, and the environmental protection is fully up to standard;
Taking municipal sludge as an example, the moisture content before treatment is 95%, the moisture content of the mud cake after treatment is 60%, and the sludge reduction is 8 times; the moisture content before industrial sludge treatment is 95%, the moisture content after treatment is 40%, and the sludge is reduced. 11 times!
Dingsheng sludge dryer has a working cycle of 40min-70min, set the program to run automatically, the sludge treatment is more efficient, the treatment effect is more precise and stable, and the sludge treatment is faster and slower once, and one treatment is not enough once. Hey.
Which sludge treatment projects use sludge deep dewatering equipment?
Dewatering of sludge is a common feature of classical sludge disposal projects
Deep Dewatering Project of Tianshan WWTP: This sludge disposal project has a total investment of 26 million yuan and can process sludge to a moisture content of less than 60%. It is the main project for sludge treatment in the sewage treatment plant in downtown Shanghai. The project uses sludge concentration + reagent conditioning + sludge deep dewatering process for sludge disposal.
Shanghai Bailonggang Wastewater Treatment Plant Sludge Treatment Project: After the completion of this project, Shanghai Bailonggang Wastewater Treatment Plant is responsible for production and operation, and has considerable influence in China. This project uses sludge anaerobic digestion + biogas purification + sludge drying process. Through the understanding of the entire sludge disposal process, it is found that the sludge produced after digestion and other stages enters the mud storage tank and is carried out by sludge deep dewatering equipment. Dehydrated in depth and then sent to the drying machine room.
Beijing Gaobeidian Wastewater Treatment Plant Sludge Advanced Digestion Project: The sludge daily treatment capacity of the project is 1358 tons of sludge with 80% moisture content. It is currently the largest sludge thermal hydrolysis + advanced anaerobic digestion + deep dewatering project in China. . After the sludge is treated by anaerobic digestion, the sludge is deeply dehydrated and reused, which has a good demonstration role in the sludge disposal project in China.
Hubei Xianning Electric Infiltration Sludge High Dry Dewatering Project: This project mainly treats sludge from municipal sewage treatment plants and uses sludge mechanical drying process to dispose of sludge. The sludge with high water content in the sewage treatment plant is treated to form a sludge cake with a water content of 60% or less to realize sludge reduction.
Shenzhen Nanshan WWTP sludge treatment system upgrade project: This project mainly deals with sludge from Nanshan WWTP, the largest sewage treatment plant in Shenzhen. The sludge with a daily processing capacity of 800 tons and a water content of 80% is treated by a process of concentration, quenching and tempering and deep dehydration.
Choose a sludge deep dewatering equipment, and the traditional sludge filter press will bring you all the sludge dewatering problems. A wise choice to determine the good operation of the sludge disposal project for several years.
Zhengzhou Dingsheng main business:
Fixed sludge treatment equipment: sludge deep dewatering equipment such as sludge filter press and sludge dryer
