Compact turbid circulating water treatment station

Abstract

The invention relates to a compact turbid circulating water treatment station. The compact turbid circulating water treatment station comprises a horizontal sedimentation pond, a mud residue tank, a sand filter, a cooling tower, a water cooling pond, a sludge tank, a sludge thickening pond, a centrifugal dehydrator, dosing equipment, a station building framework, a water pump system and a sludge pump system. The compact turbid circulating water treatment station adopts a three-dimensional arrangement, so that the occupied area of the water station is optimized to the maximum extent, and the water treatment station is conveniently arranged; single space can be fully utilized; the compact turbid circulating water treatment station is suitable for new projects and technical innovation. Wastewater in the water treatment station is in cascade use, so that water is efficiently saved and sewage discharge is reduced. A simple and efficient technology for sludge treatment has the advantages ofless sludge, convenience in operation and reduced treatment cost and outbound cost.

Description

technical field [0001] The invention relates to the field of continuous casting and hot rolling equipment for metal casting, in particular to a compact turbid ring water treatment station. Background technique [0002] Continuous casting turbid ring water is mainly produced in the processes of spray cooling of sector section, clamping rod, direct cooling of frame, flame cutting machine, slag granulation of billet, rapid water cooling device and flame cleaning machine. Hot rolling turbid ring water is mainly produced in various processes such as cooling of rolls, cooling of conveying roller tables, and high-pressure descaling (washing scale and slag). During the generation of turbid ring water, not only the water temperature will rise, but the water quality will also be polluted. The main pollutants in the turbid water are suspended iron oxide scale solid phase particles and various oil stains. [0003] At present, the commonly used water treatment process for continuous ca...

AI Technical Summary

Problems solved by technology

[0006] Continuous casting and hot rolling sludge often contain oil, and the dehydration of the plate and frame filter press is difficult, and the filter cloth is easy to be fouled, so a large amount of lime needs to be added, resulting in a large increase in the amount of dry sludge. Can only run intermittently

Belt filter press, etc. also need to add a large amount of lime, and the dehydration rate is low, and the amount of mud cake is large
