Problems solved by technology

[0002] The traditional process for removing suspended solids from industrial wastewater in thermal power plants mainly adopts single-stage treatment of inclined plate clarifiers or dual treatment of inclined plate clarifiers and gravity filter tanks. However, the structure of inclined plate clarifiers is complex and the treatment effect is limited. Traditional gravity filters require Regular backwashing pumps and fans are used for cleaning, which consumes a lot of energy
Therefore, the traditional industrial wastewater treatment system can no longer meet the current environmental protection requirements for energy saving and emission reduction.

Abstract

The invention discloses an industrial wastewater treatment system for a thermal power plant. The industrial wastewater treatment system is characterized by comprising a wastewater storage basin, a wastewater delivery pump, a PH regulating tank, a reaction trough, a solid contact clarifying basin, an efficient quick sand filter, a neutralization basin and a drain basin which are sequentially communicated with one another, wherein the bottom of the solid contact clarifying basin is communicated with a sludge treatment system. The advanced solid contact clarifying basin and the efficient quick sand filter are adopted to perform dual removal on suspended substances, so that suspended substances in the treated wastewater are not greater than 10ppm, so that the treated wastewater is recyclable. The efficient quick sand filter adopted in the system is of high-tech environment-friendly product with a unique design; the up-flow fluid bed filtration theory and a single homogeneous filtering material are adopted, filtration and elutriation are performed at the same time, flushing or back flushing can be realized without halt; a traditional high-power back flushing system is replaced by smart sand extraction and elutriation structure, so that not only can the energy consumption be greatly reduced, but also auxiliary valves and pipeline systems of the system are greatly reduced, so that the running and operating maintenance is relatively simple.
