Description

A device for sludge fermentation combined with high-concentration organic wastewater treatment

technical field

The invention relates to the field of sewage sludge treatment equipment, in particular to a sludge fermentation cooperative high-concentration organic wastewater treatment device.

Background technique

Wastewater oxidation treatment method is a kind of wastewater chemical treatment method. It is a method of using strong oxidants to oxidize and decompose pollutants in wastewater to purify wastewater. It has become an important means of controlling biologically refractory organic and toxic pollutants. , Papermaking, electroplating and printed boards, pharmaceuticals, hospitals, mines, landfill leachate and other wastewater treatment have been applied.

At the same time, sludge wet oxidation refers to the use of wet oxidation method to treat sludge. Usually, the sludge is placed in a closed reactor, and air or oxygen is introduced into the oxidant under high temperature and high pressure conditions. It is used according to the principle of submerged fuel. The organic matter in the sludge is oxidatively decomposed, and the organic matter is converted into an inorganic matter, including processes such as hydrolysis, cracking and oxidation.

At present, in the process of blowing air into the sewage and using the oxygen in the air to oxidize the sewage, the noise of the air compressor is large, and the vibration of the air compressor during operation is large, which will cause environmental pollution. Greater noise pollution.
