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

Abstract

The invention discloses biochemical sludge conditioning equipment. The equipment is characterized by comprising a pressure sludge storage tank; the pressure sludge storage tank is provided with a sludge feeding opening with a sealing opening and closing cover; the pressure sludge storage tank is also provided with a high-pressure gas inlet; a high-pressure gas pipe communicates with the external part of the high-pressure gas inlet; a gas pipe switching valve is arranged on the high-pressure gas pipe; a high-pressure gas adding device is arranged at one end, far away from the pressure sludge storage tank, of the high-pressure gas pipe; the pressure sludge storage tank is also provided with a release opening; a safe release device is arranged at the release opening; the safe release device comprises a metal connecting head; the connecting head is fixedly connected at the release opening; a release channel communicating with the release opening is arranged in the connecting head; and a rupture disk is arranged in the release channel. With the equipment provided by the invention, the subsequent dehydration effect of the sludge can be better improved, and the equipment has the advantages of simple structure, convenient operation, high processing efficiency, no side effect and the like.

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...
