A continuous alternate mbbr sewage treatment method and equipment

Abstract

The invention provides a continuous alternating MBBR sewage treatment method and equipment. The treatment method is as follows: firstly, the granular suspended impurities in the sewage are removed through pretreatment, and the water quality and water quantity of the sewage are balanced, and then the anaerobic / anoxic / aerobic alternating operation mode is used to release anaerobic phosphorus from the sewage , Simultaneous denitrification and nitrification treatment, which improves the removal efficiency of pollutant matrix. The treatment equipment includes a homogeneous room, a pre-denitrification room, a transition room, an aerobic room, an aerobic tank, a high-efficiency sedimentation tank and an equipment control room that are connected in sequence through the water pipeline; the equipment control room is equipped with ultraviolet disinfection equipment, pipeline increasing Pressure pump, automatic filter tank, aeration fan and PLC control device. The treatment equipment has a high degree of integration, strong functionality, simple and convenient installation and operation of the equipment, small footprint, high space utilization rate, and enhanced long-term operation stability, and the treatment energy consumption and operation and maintenance cost of the whole set of sewage treatment equipment are low .

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a continuous alternating MBBR sewage treatment method and equipment. Background technique [0002] With the increasing pollution of water environment, the problem of water environment pollution has become a hot spot in the field of environmental protection at home and abroad. In view of the dispersion, extensiveness and uncertainty of water quality and quantity of sewage in small cities and towns in my country, the traditional sewage treatment process has been far away from the multi-functionality of pollutant removal, high efficiency and stability, convenient operation and economic rationality. Therefore, it is necessary to develop, research and apply new sewage treatment processes and technologies, and seek one or more advanced sewage treatment technologies with high efficiency, low consumption, convenient operation, low investment cost and low operation and maintenance...

Problems solved by technology

In view of the dispersion, extensiveness and uncertainty of water quality and quantity of sewage in small cities and towns in my country, the traditional sewage treatment process has been far away from the multi-functionality of pollutant removal, high efficiency and stability, convenient operation and economic rationality. Therefore, it is necessary to develop, research and apply new sewage treatment processes and technologies, and seek one or more advanced sewage treatment technologies with high efficiency, low consumption, convenient operation, low investment cost and low operation and maintenance cost that are more suitable for my country's national conditions. Treatment technology has become the key to research in the field of water pollution prevention and control engineering around the world
