Abstract

The invention discloses a secondary sludge screening system for compound solidification treatment of river and lake sludge, which comprises an external structure, a tank wall is arranged at the inner middle part of the external structure, an inclined tank wall is fixedly installed on the top of the tank wall, and an inclined tank wall is fixed in the middle of the tank wall. The part is fixedly installed with the installation shaft, the end of the installation shaft is fixedly installed with the motor, the bottom of the motor is fixedly installed with a bracket, the top of the inclined tank wall is fixedly installed with a cover, the inside of the cover is provided with a discharge hole, and the middle part of the cover is fixedly installed There is a top cover motor, the main shaft of the top cover motor is fixedly installed with a screw, the top of the cover is sealed and fastened with a top cover, the surface of the inclined tank wall is fixedly equipped with a discharge device, the inside of the tank wall is filled with mixed liquid, and the middle part of the mixed liquid The isolation cover is fixedly installed, the inner middle part of the isolation cover is fixedly installed with a built-in cylinder, the middle part of the built-in cylinder is fixedly installed with a limit plate, the top of the limit plate is fixed with a dislocation motor, and the top of the dislocation motor is fixed with a turntable filter device .

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular to a secondary sludge screening system for compound solidification treatment of river and lake sludge. Background technique [0002] Sludge treatment is the process of thickening, conditioning, dehydrating, stabilizing, drying or incinerating sludge. There are many methods that can be used to treat oily sludge. Chemical and physical methods such as incineration, chlorine oxidation, ozone oxidation and combustion, biological treatment methods such as bioremediation, traditional composting, etc. Now, with the development of technology, low-temperature cold treatment and bioremediation of oily sludge have become two effective treatment methods. [0003] The devices in the prior art often use filter devices in the process of treating sludge to firstly remove the pollutants with larger particles in the sludge, so as to facilitate further physical and biochemical treatment of t...

AI Technical Summary

Problems solved by technology

[0003] The devices in the prior art often use filter devices in the process of treating sludge to firstly remove the pollutants with larger particles in the sludge, so as to facilitate further physical and biochemical treatment of the sludge; but now In the process of filtering particulate pollutants in some devices, the filtered particles often remain on the surface of the filter plate, and the filter element needs to be replaced to allow the filter plate to perform the filtering operation again. It is also very inconvenient to disassemble the sludge, which is not conducive to efficient sludge filtration.
