Abstract

The invention relates to a method for treatment of wastewater by a circular sedimentation tank with a mechanical sludge discharge device. The method includes the steps of: letting to-be-treated wastewater enter a central cylinder through a water inlet pipe, distributing the to-be-treated wastewater to a sludge-water separation device through the central cylinder, completing sludge-water separationby filler in the sludge-water separation device, then converging clear water by a drainage groove into a water outlet groove, and performing discharging by a water outlet, letting the separated sludge fall to the bottom of a sedimentation tank main body, collecting the sludge through a sludge scraper and then performing discharging. The method provided by the invention can be used for large-scalewastewater treatment, at the same time has the advantages of simple operation, strong adaptability, stable operation and the like, also can improve the precipitation efficiency by 50-60%, and reducethe suspended matters in the water discharged from the system to 5-25mg / L.

Description

technical field

[0001] The invention relates to a method for treating waste water by using a circular sedimentation tank equipped with a mechanical mud discharge device, and belongs to the technical field of environmental protection water treatment and purification. Background technique

[0002] In recent years, with the gradual implementation of national environmental protection policies, industrial enterprises have gradually strengthened their investment in sewage treatment systems. Due to the relatively low per capita water consumption in our country, the cost of industrial water use is increasing year by year, and the requirements for sewage discharge are also constantly improving and becoming stricter. The papermaking wastewater discharge standard requires SS≤30mg / L, and the effluent suspended solids after treatment in ordinary sedimentation tanks is generally between 30 and 50 mg / L, and the effluent suspended solids index cannot meet the discharge standard requirements...
