Sewage treatment equipment suitable for sewage treatment in industrial park

Abstract

The invention discloses sewage treatment equipment suitable for sewage treatment in an industrial park, relates to the field of sewage treatment, and solves the problems that a production wastewater pool involved in an existing industrial park sewage treatment device only mixes a treatment agent with sewage through a mixing stirrer, so that the mixing efficiency is low, and the sewage treatment effect is poor. And secondly, the sewage is inconvenient to prefilter when entering a production wastewater pool, so that some impurities (such as solid pollutants, suspended matters and colloidal impurities) which do not react with treatment chemicals enter the wastewater pool together, and the accumulated impurities can influence the stirring effect of a mixing stirrer and the use effect of the treatment chemicals at the same time. The sewage treatment device is technically characterized by comprising a filtering device for filtering impurities in sewage; the settling pond is connected with the filtering device, and the settling pond is used for settling. The treatment efficiency is ensured, the structure is relatively simple, and the use is convenient.
