Industrial wastewater combined utilization treatment device

Abstract

The invention discloses an industrial wastewater combined utilization treatment device, and belongs to the technical field of wastewater treatment. The industrial wastewater combined utilization treatment device includes a sedimentation tank, the left end of the sedimentation tank is connected to a water inlet pipe and a sludge discharge pipe, the water inlet pipe is positioned above the sludge discharge pipe, the right end of the sedimentation tank is connected to a water outlet pipe, a middle partition wall matched with the sedimentation tank is fixedly connected into the sedimentation tank,the left end of the middle partition wall is slidably connected to a floating plate platform, a dry sewage pump is mounted at the upper end of the floating plate platform, the left end of the dry sewage pump is connected to a water pumping pipe, the lower end of the water pumping pipe extends to the lower side of the floating plate platform, and the upper end of the dry sewage pump is connected to a drain pipe. According to the invention, disturbance caused by the drainage process to sludge at the bottom of the sedimentation tank can be effectively reduced in the drainage process of the sedimentation tank, meanwhile, float sludge in a water body can be filtered, so that the water quality of the recycled water body is effectively guaranteed, and in addition, workers can conveniently cleanand recycle the filtered float sludge.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, and more specifically relates to a combined utilization treatment device for industrial wastewater. Background technique [0002] Industrial wastewater includes production wastewater, production sewage and cooling water. It refers to wastewater and waste liquid generated in the process of industrial production, which contains industrial production materials, intermediate products, by-products and pollutants generated in the production process lost with water. Industrial wastewater often contains a variety of toxic substances, which will not only pollute the environment, but also cause harm to human health. Therefore, it is necessary to develop comprehensive utilization, turn harm into benefit, and take corresponding purification measures for disposal according to the composition and concentration of pollutants in wastewater Only then can it be discharged. [0003] In the industrial ...

Problems solved by technology

[0004] However, with the long-term use of the sedimentation tank, some sludge in the sedimentation tank is prone to anaerobic fermentation, causing the sludge to float. In addition, when the staff drains the sedimentation tank, the drainage process is likely to cause damage to the sludge at the bottom of the sedimentation tank. Greater disturbance will also cause part of the sludge to float up, and the floating sludge in the water body will be discharged out of the sedimentation tank together with the water body, causing greater pollution to the
