Problems solved by technology

[0003] The traditional AAO decentralized sewage integrated equipment is a set of overall equipment. In order to ensure that the various indicators of wastewater treatment can meet the standards, a biochemical sedimentation tank and a flocculation sedimentation tank are usually installed after the aerobic tank to adjust the return flow and improve the process. , this method cannot accurately control the split flow of the water flow, and cannot adjust according to the split flow or return flow ratio of the water flow. In addition, this method also has the problems of large equipment footprint and low equipment operation efficiency

Abstract

The invention belongs to the technical field of water treatment equipment, in particular to an adjustable reflux device suitable for sewage integrated wastewater treatment equipment. The device comprises a water pool body, partition plates are arranged in the water pool body, and the interior of the water pool body is divided into different functional areas by the partition plates. The device further comprises a flow adjusting mechanism which can adjust the flow and proportion of water entering the different functional areas. By adopting the reflux device, space can be saved, and the reflux quantity can be adjusted as required. When the water inlet amount of the integrated equipment is relatively low, circular flowing of water can be guaranteed, occupied space of original equipment is reduced, and the space of the equipment can be efficiently utilized. Flora in the adjustable reflux device can be in the optimal state, the adjustable reflux device can obtain a good ammonia nitrogen andCOD removal effect, the equipment can efficiently operate, and the equipment can be widely used in the field of environment-friendly equipment.

Description

technical field [0001] The application belongs to the technical field of water treatment equipment, and in particular relates to a backflow device suitable for sewage integrated wastewater treatment equipment. Background technique [0002] my country is vigorously building a new countryside, building an ecological civilized society, and realizing rural revitalization. However, in rural areas where the residences are scattered and the municipal facilities are not perfect, there are no relatively centralized sewage treatment plants, and the scattered sewage produced by each household is generally They are directly discharged, seriously restricting the pace of rural revitalization. Distributed integrated sewage treatment technology, as a small sewage treatment facility, can solve domestic sewage generated in remote areas such as new rural areas and tourist resorts. [0003] The traditional AAO decentralized sewage integrated equipment is a set of overall equipment. In order to ...
