Problems solved by technology

At present, most waste-to-energy power plants adopt simple pretreatment processes, which have not achieved the reduction and ratio optimization of high-load pollutants, which has laid a huge hidden danger for the back-end biochemical advanced treatment (such as SBR, UASB)
It also leads to the problems of short service life of back-end equipment, high maintenance cost and high operation cost

Abstract

The invention provides an integral pretreatment device for leachate in a waste incineration power plant. The device is arranged before rear-end biochemical treatment, has the characteristics of capability of efficiently degrading organic macromolecules, adjusting the carbon-nitrogen ratio and improving the biodegradability of the leachate, and is low in land cost due to small occupied area. The device comprises a shell and is characterized in that the shell is vertically arranged; an aeration dosing silt removal region, a mud-water separation region, an ammonia nitrogen blowoff region and a waste gas collection region are arranged in the shell in sequence from bottom to top; a mixed reaction cavity is formed in the top of one side of the shell; a water-passing hole is formed in the side wall, in the ammonia nitrogen blowoff region, at the upper part of the shell; the water-passing hole is communicated with the mixed reaction cavity in the outer side; an electrolysis and micro-electrolysis mixed reactor is arranged in the mixed reaction cavity; a doser is also arranged in the mixed reaction cavity; a three-phase separator is arranged in the mud-water separation region.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to an integrated pretreatment device for leachate of a waste incineration power plant. Background technique [0002] The leachate of waste incineration power plants belongs to the "three high" wastewater with high organic matter, high ammonia nitrogen and high salinity, and the difficulty and cost of treatment are relatively large. At present, most of the waste-to-energy power plants adopt simple pretreatment processes, which have not achieved the reduction and ratio optimization of high-load pollutants, which has laid a huge hidden danger for the back-end biochemical advanced treatment (such as SBR, UASB). It also leads to the problems of short service life of back-end equipment, high maintenance cost and high operation cost. [0003] Therefore, according to the characteristics of "three high" wastewater, a set of integrated pretreatment equipment was developed to int...
