Integrated efficient environment-friendly sewage treatment mechanism

Abstract

The invention discloses an integrated efficient environment-friendly sewage treatment mechanism. The integrated efficient environment-friendly sewage treatment mechanism comprises a reaction tank, thereaction tank is composed of an anoxic pond, a first aerobic pond and a second aerobic tank which are sequentially connected, and biological filler is filled inside the reaction tank; a water inlet is arranged on the left of the anoxic pond, a water outlet is arranged at the top of the right end of the second aerobic tank, and a first filler blocking device is arranged at the top of the inside ofthe anoxic pond. The integrated efficient environment-friendly sewage treatment mechanism is high in denitrification and dephosphorization capacity; simply by adding a deep treatment instrument afterthe second aerobic pond, a sewage deep treatment function can be achieve, and output water can meet the categories IV of national surface water standards; during a forward flushing process, pond capacity is made full use of, and during operation, a continuous water inputting manner is applied to avoid influence on water treatment processes, and backup treatment units as well as investment and construction costs can be saved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an integrated high-efficiency sewage environmental protection treatment mechanism. Background technique [0002] In the development process of sewage treatment, due to the scale effect of large and medium-sized sewage treatment plants, large-scale has long been the development direction of sewage treatment. In recent years, due to the shortcomings of large and medium-sized sewage treatment plants, such as large investment, large land occupation, and the need to build a huge sewage collection pipe network, small and medium-sized sewage treatment processes have become the main development direction of sewage treatment processes. The treatment of sewage is changing from centralized to decentralized, from large-scale centralized to small and medium-sized decentralized. The layout of "mainly large and small and medium-sized" is in line with my country's national conditions a...

Problems solved by technology

In the normal processing process of this technology, the water level and the forward flushing water level differ greatly, and the water head loss is serious. The increase of the water level increases the head of the pump and reduces the effective utilization of the equipment; The flushing stage is utilized, and the forward flushing stage is short, so the upper space of the pool body is basically idle, resulting in a waste of pool capacity
