Embodiment Construction

[0023] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0024] In order to facilitate the understanding of the processing process of the process of the present invention, at first the structure of the special device used in this process is introduced in detail:

[0025] A special device for magnetic sludge zero-discharge sewage continuous treatment process, mainly including activated sludge aeration tank 3, ozone hydrolysis tank 19, deozonation tank 22, ozone generator 20, ozone microbubble Venturi generator 17, multiple Air pumps and multiple water pumps.

[0026]The activated sludge aeration tank is mainly composed of a tank body, an aeration pipeline system, a first magnetic drum 7 and a first scraper 9. The tank body is an open top structure, and the upper part of the left side wall of the ta...

Abstract

The invention relates to a magnetic sludge zero discharge sewage continuous treatment process and a dedicated device. Sewage is treated by an activated sludge aeration tank, an ozone hydrolysis tank and an ozone deodorization tank, separable high concentration sludge is generated according to a principle that microorganism dies and dissolves in extreme environment and adsorption and dependence ofmagnetic powder for sludge, and a set of continuous magnetic sludge rapid separation ozone sludge self-dissolving coupling novel sewage treatment process is built. The process can reduce sludge or discharge no sludge. In addition, the process has the advantages of low energy consumption and low cost and the like, overcomes defects of traditional methods, and appears in the sewage treatment field for the first time.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a magnetic sludge zero-discharge sewage continuous treatment process and a special device. Background technique [0002] With the increase in the amount of urban domestic sewage and industrial wastewater treatment, the output of excess sludge is also increasing rapidly. Only the municipal government produces 30 million to 40 million tons of municipal sludge with a water content of about 80% every year. It is estimated that by 2020, my country's municipal sludge production will reach 60-90 million tons. The volume of sludge is much smaller than the volume of sewage, but the cost of sludge disposal can account for or even exceed more than 50% of the daily consumption of the entire sewage treatment plant. The treatment and disposal of excess sludge discharged from sewage treatment has troubled people for many years Especially in recent years, the increasingly strict restri...
