Problems solved by technology

[0004] The purpose of the present invention is to provide an energy-saving and consumption-reducing sewage treatment system, in order to solve the problem that air needs to be used for aeration in the treatment process of A2O process, and the oxygen consumption of the whole process is relatively large. Usually, each treatment tank is equipped with There is an oxygen charging unit, which leads to the problem of excessive energy consumption

Abstract

The invention discloses an energy-saving and consumption-reducing sewage treatment system. The energy-saving and consumption-reducing sewage treatment system comprises an adjustment tank, an anaerobictank, an anoxic tank and a sedimentation tank, wherein an oxygen filling device is arranged above the anoxic tank; the upper end of the oxygen filling device is provided with a water ejector; the middle part of the oxygen filling device is provided with a biofilm; the upper part of the oxygen filling device is provided with a plurality of exhaust pipelines; the lower end of the oxygen filling device is provided with a drainage pipeline; the exhaust pipelines are connected to an oxygen requiring position of the sewage treatment system respectively; valves are arranged on the exhaust pipelinesand the drainage pipeline. By adopting the energy-saving and consumption-reducing sewage treatment system, the problems of higher oxygen consumption and higher energy consumption in the sewage treatment process are solved.

Description

Technical field [0001] The invention relates to sewage treatment, in particular to an energy-saving and consumption-reducing sewage treatment system. Background technique [0002] Sewage treatment refers to the process of purifying sewage to meet the water quality requirements for discharge into a water body or reuse. The sewage treatment can be divided into primary treatment, secondary treatment and tertiary treatment according to the degree of treatment. The BOD removal rate of the wastewater after the primary treatment is 20%, which is still not suitable for discharge. After the secondary treatment, the colloidal and dissolved organic matter in the wastewater is greatly removed, and the BOD removal rate is 80%~90% to reach the emission standard; The secondary treatment is to remove suspended solids in the sewage through simple sedimentation, filtration or appropriate aeration, and the secondary treatment is to further purify the sewage through the aeration tank and sedimentati...
