A kind of biochemical sludge conditioning equipment

Abstract

The invention discloses a biochemical sludge conditioning equipment, which is characterized in that it comprises a pressure sludge storage tank, the pressure sludge storage tank has a sludge discharge port with a sealed switch cover, and the pressure sludge storage tank is also provided with The high-pressure gas inlet, the high-pressure gas inlet is connected with a high-pressure gas pipe, and the high-pressure gas pipe is provided with a gas pipe switch valve, and the end of the high-pressure gas pipe far away from the pressure sludge storage tank is also provided with a high-pressure gas adding device; the pressure sludge storage tank is also provided with There is a discharge port, and a safety discharge device is provided at the discharge port. The safety discharge device includes a metal connector, which is fixedly connected to the discharge port, and a discharge channel connected to the discharge port is provided in the connector , a burst disc is set in the discharge channel. The invention can better improve the subsequent sludge dehydration effect; and has the advantages of simple structure, convenient operation, high treatment efficiency and no side effects.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a treatment and conditioning equipment for sewage treatment product sludge. Background technique [0002] Sludge is an associated product in the process of sewage treatment in urban sewage plants, especially after sewage treatment by activated sludge method, a large amount of sludge will be produced. Usually, nearly 1 / 3 of the organic matter is converted into sludge during sewage treatment, which contains a large amount of organic pollutants, pathogenic microorganisms, heavy metals, etc. Therefore, there are many kinds of organic pollutants in sludge, including chlorinated phenols, polycyclic aromatic hydrocarbons, nitrobenzenes, amines, halogenated alkanes, etc. Some of these organic pollutants can remain stable in the environment for a long time. The influence of the air environment can easily breed bacteria and cause many diseases in humans or other organisms. There...

AI Technical Summary

Problems solved by technology

[0005] The above sludge conditioning methods all have relatively large limitations, and their impact on subsequent sludge dehydration is not high

The conditioning method of existing sewage plants is mainly chemical conditioning, and the addition of polyacrylamide and other polymer flocculants greatly increases the cost of sludge treatment
