High-concentration organic wastewater treatment system

Abstract

The invention relates to a high-concentration organic wastewater treatment system. The treatment system comprises an adjusting adsorption tank, a solid-liquid separation machine, a coagulating sedimentation reactor, a fixed interval filter, a sludge homogenizing tank and a draught fan, wherein the solid-liquid separation machine is communicated with the adjusting adsorption tank, the coagulating sedimentation reactor is communicated with the solid-liquid separation machine, the coagulating sedimentation reactor is communicated with the coagulating sedimentation reactor, the sludge homogenizing tank is communicated with a facultative aerobic membrane bioreactor and a UASB reactor, respectively, and the draught fan is connected with the facultative aerobic membrane bioreactor and a contact oxidation reactor, respectively and is used for aerating the facultative aerobic membrane bioreactor and the contact oxidation reactor. The high-concentration organic wastewater treatment system has the beneficial effects that a biological sludge treatment system can be omitted in the whole process, each unit is strong in volume load and impact resistance, and the construction investment is furthest reduced; and the high-concentration organic wastewater treatment system is applicable to the design of high-concentration organic wastewater, and acceptable COD of inflow reaches up to 20000mgl-100000mg / l.

Description

technical field [0001] The invention relates to a water treatment system, in particular to a high-concentration organic wastewater treatment system. Background technique [0002] At present, the treatment process of organic wastewater such as domestic sewage is mainly composed of two processes of sedimentation and aeration (the corresponding wastewater treatment system includes sedimentation tank and aeration tank). For wastewater (such as wastewater from pastures, farms, or domestic organic wastewater with concentrated population), wastewater treatment is very difficult and costly due to the large sludge output and high organic load; and the odor pollution of wastewater treatment stations is particularly serious. Contents of the invention [0003] The purpose of the present invention is to provide a high-concentration organic wastewater treatment system in order to overcome the deficiencies of the prior art. [0004] In order to achieve the above object, the technical so...
