The following measures can be taken to solve the problem of high sludge concentration in urban sewage treatment plants:
1. Optimize the sewage removal reaction process. The high sludge concentration in urban sewage treatment plants may be due to the decline in the reaction rate of activated sludge, incomplete accumulation of active components in the sewage removal reaction, insufficient pretreatment, etc. Therefore, it is necessary to optimize the treatment process to reduce the generation of sludge and restore its concentration to normal levels.
2. Reduce the discharge of sewage. Optimizing the sewage removal reaction process can only reduce the concentration, but not the amount of sludge generated. Therefore, measures should be taken to reduce the discharge of sewage to reduce the amount of sludge generated and maintain the stability of sludge concentration.
3. Waste residue and sludge dewatering equipment. The sewage treatment plant should be upgraded and renovated to have waste residue and sludge dewatering equipment to achieve the purpose of reducing the concentration of sludge, thereby achieving the purpose of saving waste residue and sludge generation.
4. Sludge digestion treatment. A sludge digestion circulation treatment system can be set up in the plant to reduce or control the sludge concentration. After digestion treatment, highly usable sludge is produced, which can be used as agricultural soil or industrial land, etc.
5. Sludge transportation. Sludge can be transported to a specially treated treatment site through sludge transportation to further reduce the sludge concentration.
In addition, in terms of meeting relevant quality standards, urban sewage treatment plants should also strictly implement relevant policies and regulations, control the discharge concentration of sewage, and ensure that treatment facilities are safe, effective, and environmentally friendly, so as to achieve green and environmentally friendly social and economic sustainable development.
