Sewage uniform distribution treatment device for aerobic granular sludge system and application method for sewage uniform distribution treatment device

Abstract

The invention relates to a sewage uniform distribution treatment device for an aerobic granular sludge system and an application method for the sewage uniform distribution treatment device. The sewageuniform distribution treatment device comprises a reactor tank body, water inlet devices and water outlet devices; each water inlet device comprises a water inlet inner channel, a water inlet weir, awater inlet outer channel, a vertical water inlet branch pipe and a vertical horn-shaped opening; the water inlet weirs are located at the tops of the water inlet inner channels and are connected tothe water inlet inner channels; the vertical water inlet branch pipes are vertically arranged in the reactor tank body; the upper ends and the lower ends of the vertical water inlet branch pipes are connected to the water inlet outer channels and the vertical horn-shaped openings correspondingly; each water outlet device comprises a main water outlet pipe, a water outlet channel, a water outlet weir, an outer flow baffle and an inner flow baffle; the water outlet channels are connected to the main water outlet pipes; the outer flow baffles are vertical flow baffles; and the inner flow bafflesare positioned at the bottoms of the water outlet channels, are connected to the water outlet channels and are arranged in a certain included angle with the water outlet channels. The sewage uniform distribution treatment device and the application method thereof have the advantages of being reasonable in structural design, convenient to operate and use, low in operation energy consumption, low inlater maintenance cost and capable of achieving the ideal contact effect between organic matter and sludge.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage uniform distribution treatment device and a use method thereof. Background technique [0002] China's water pollution problem is serious, and the traditional water distribution method has problems such as high cost, high energy consumption, and unsatisfactory contact between organic matter and sludge. In ordinary activated sludge projects, the water distribution method mostly adopts the front-to-back push-flow type, and the fresh sewage enters the biological tank to mix with the raw water, reducing the organic load of the fresh sewage, which is not conducive to the anaerobic phosphorus release and denitrification of the sludge. Therefore, it is of great practical significance to develop a new technology and new process with low operating cost, low energy consumption, and full contact with organic matter and sludge in sewage to overcome the limitations of traditi...
