Problems solved by technology

Due to the strong hydrophilicity of the excess sludge, the sludge dehydration rate is difficult. The sludge after conventional dehydration is huge, which brings great difficulties to the factory transportation. If the excess sludge is not handled properly, it will cause a series of problems. Environmental problems, the most commonly used sludge treatment method is to use chemicals for treatment, but the efficiency of existing chemicals for sludge treatment is not high, which brings inconvenience to people's use

Description

technical field [0001] The invention relates to a medicament, in particular to a high-efficiency sludge treatment agent. Background technique [0002] Sewage, usually refers to certain polluted discharge water from domestic and production. Sewage mainly includes domestic sewage, industrial wastewater and initial rainwater. The main pollutants of sewage are pathogenic pollutants, oxygen-consuming pollutants, plant nutrients and toxic pollutants. In order to protect the environment and reuse resources, people will treat sewage, which will produce a large amount of residual sludge. The treatment of excess sludge is a major problem in sewage biochemical treatment. Sludge aggregates with scum and microbial clusters in sewage to form excess sludge in sewage plants. The excess sludge contains a large amount of harmful microorganisms such as germs and parasite eggs, and also contains a large amount of toxic heavy metals such as copper, mercury, and chromium, and carcinogenic subs...
