Abstract

The invention provides an integrated A/O/MBBR (Moving Bed Biofilm Reactor) reactor with denitriding function. The integrated A/O/MBBR reactor comprises a circular barrel body, a water inlet distributing device, suspension fillers, a submersible centrifugal aerator, suspension fillers and an air inlet pipeline; the circular barrel body is separated into an anoxic area, an aerobic area, a flow guide area, a mud-water separating area and a water collecting area by a plurality of concentric cylindrical partition plates; the water inlet distribution device is arranged at the upper part of the anoxic area; the suspension fillers are arranged in the middle part of the anoxic area; the submersible centrifugal aerator is arranged at the bottom part of the anoxic area; the suspension fillers are arranged in the middle part of the aerobic area; and the air inlet pipeline is connected with an air inlet of the submersible centrifugal aerator.

Description

technical field [0001] The invention relates to a sewage treatment device, in particular to an integrated A / O / MBBR reactor. Background technique [0002] In recent years, with the rapid development of China's economy, the pollution of water environment has become increasingly serious. For this reason, the country has invested a lot of money in the construction of centralized sewage treatment plants and supporting sewage collection pipe networks, and achieved certain results in maintaining and improving the water environment. However, However, the construction of a centralized sewage treatment plant has problems such as large investment scale, long construction period, the need to build a sewage collection pipe network, and difficulty in site selection and land acquisition. For a large amount of rural sewage and industrial wastewater and domestic sewage in areas far from urban areas, it is urgent Relying on the construction of a centralized sewage treatment plant is often dif...
