Abstract

The invention provides a device and a method for sludge treatment. The device for the sludge treatment comprises a membrane rupture reactor, an ozonator and a coagulation reactor, wherein an aerating apparatus is arranged on the bottom and / or the side wall of the membrane rupture reactor, an outlet of the ozonator is connected with an air inlet of the aerating apparatus, and a feeding outlet of the membrane rupture reactor is connected with a feeding inlet of the coagulation reactor. When the device for the sludge treatment is used for treating sludge, the sludge to be treated, oxidation guiding catalysts and ozone generated by the ozonator have a redox reaction with each other in the membrane rupture reactor, then achieved reaction products are delivered into the coagulation reactor to be through coagulation treatment, then achieved sludge which is through the coagulation treatment is concentrated and filter pressed, and the sludge treatment is completed. When the device for the sludge treatment is used for treating sludge, the redox reaction and the coagulation treatment are carried separately, so that under the condition that all materials are input continuously, the sludge treatment can be carried out continuously, and efficiency of the sludge treatment is improved.

Description

technical field

[0001] The invention relates to the technical field of sludge treatment, and more specifically relates to a sludge treatment equipment and method. Background technique

[0002] After the sewage is treated, a large amount of residual sludge will be produced. The treatment and disposal of excess sludge is a major problem in sewage biochemical treatment. The basic principle of secondary biochemical treatment of sewage plant sewage is that microorganisms use organic matter in sewage as nutrients for their own metabolism, decompose them, and convert them into CO 2 、H 2 0 and metabolic secretions. The residual secretions produced by the metabolism of microorganisms form excess sludge, which aggregates with scum in sewage and microbial clusters to form excess sludge in sewage plants, which is a secondary product after biochemical treatment of sewage in sewage plants. It has also become urban solid waste.

[0003] As we all know, sludge contains a large number o...
