Description

Sludge coagulation reaction device

Technical Field

The utility model belongs to the technical field of sludge treatment, concretely relates to sludge coagulation reaction unit.

Background

The sewage is treated to produce a large amount of excess sludge. The treatment and disposal of excess sludge is a great problem in the biochemical treatment of sewage. The basic principle of the secondary biochemical treatment of sewage in sewage plants is that microorganisms take organic matters in the sewage as nutrient substances for self metabolism, decompose the organic matters and convert the organic matters into CO2, H20 and metabolic secretions. The residual secretion generated by the metabolism of the microorganisms forms excess sludge, and the excess sludge, scum in sewage and microorganism bacteria are combined to form the residual sludge of the sewage plant, which is a secondary product after the biochemical treatment of the sewage plant and also becomes urban solid waste. It is known that sludge contains a large amount of harmful microorganisms such as pathogenic bacteria and parasitic ova, and also contains a large amount of toxic heavy metals such as arsenic, copper, mercury, chromium, and carcinogenic substances such as dioxin. Due to the fact that the bacterial colloid polymer of the sludge is high in hydrophilicity, the sludge dehydration rate is difficult, the sludge volume is large after conventional dehydration, and great difficulty is brought to sludge transportation of a factory. If the sludge treatment and disposal of the urban sewage plant is improper or the treatment and disposal are not standard, a series of environmental problems can be caused. If the water content is high, a large amount of harmful penetrating fluid is caused when the water is buried, and a blowout phenomenon occurs when the water is serious, and the water causes new potential threat to the ecological environment. Therefore, sludge treatment and disposal are not only a delicate issue in the environmental field, but also one of the current hot issues in the environmental field. At present, the treatment method of the excess sludge mainly comprises sanitary landfill, comprehensive utilization of land, heat treatment, sludge composting, an ultrasonic sludge digestion method and the like.

The sludge coagulation reaction mainly reduces the water content of sludge, the existing sludge coagulation reaction device can not sterilize and remove peculiar smell to harmful gas generated in the reaction process when in use, and after the reaction, the condition that the discharge opening is blocked by sludge is easily generated when the discharge is reduced due to the water content of the sludge, and the sludge is easily adhered to the inner wall of the reaction device.
