Sewage purification treatment device

Abstract

The invention discloses a sewage purification treatment device which is characterized in that the device comprises a rough washing device, a fine washing device, a rinsing device, a sewage treatment system, a reuse water tank and a water system for watering coal. Sewage outlets of the rough washing device and the fine washing device are communicated with an influx tank, a discharge opening of which is communicated with the water system for watering coal. A sewage outlet of the rinsing device is communicated with the sewage treatment system. A reuse water discharge opening of the sewage treatment system is communicated with the reuse water tank. An up-to-standard water discharge opening of the sewage treatment system is communicated with an extraneous drainage system. By the utilization of the sewage treatment system and related devices, difficulties such as low sewage reuse rate and high operating cost in present various cleaning industries are thoroughly solved. The whole treatment flow adopts mechanical automatic control, the antifouling effect is good, and operating cost is low. By different treatment means according to different water qualities, sewage discharge amount is effectively controlled, and operating cost for sewage treatment in enterprises is also greatly reduced.

Description

technical field [0001] The invention relates to a sewage purification treatment device, in particular to an environment-friendly sewage treatment device suitable for the cleaning industry, which can effectively control the sewage discharge amount and is close to zero discharge. Background technique [0002] In actual production activities, various cleaning industries generate a large amount of waste water in the production process, especially the recycling waste used by industries that use waste recycled raw materials for resource recycling. Effective and timely treatment will inevitably lead to serious pollution of groundwater and rivers. The traditional prevention and control method is to collect and collect the wastewater in the rough washing, fine washing and rinsing stages of the raw materials, and then treat it through the sewage treatment system and discharge part of it, and reuse the other part, which not only causes water pollution, but also increases the number of ...

AI Technical Summary

Problems solved by technology

[0002] In actual production activities, various cleaning industries produce a large amount of wastewater in the production process, especially the recycled waste used in industries that use waste recycled materials for resource regeneration. After cleaning, a large amount of high-concentration wastewater is produced, and the pollution is particularly serious. If not Effective and timely treatment will inevitably lead to serious pollution of groundwater and rivers

The traditional prevention and control method is to collect and collect the waste water in the stages of rough washing, fine washing and rinsing of raw materials, and then discharge part of it through the sewage treatment system, and reuse the other part, which not only causes water pollution, but also increases the cost of enterprises. operating costs, and the waste water reuse rate is also low
