Abstract

The invention relates to a device for recovering and treating surface treatment wastewater. The device comprises an oil separation tank; a water tank and an agent tank are arranged at one side of the oil separation tank; a pipeline mixer is arranged at one side of the water tank and the agent tank; a first pipeline is arranged on the water tank; a second pipeline is arranged on the agent tank; the first pipeline and the second pipeline are connected with one end of the pipeline mixer; a water distribution tank is arranged above the pipeline mixer; a third pipeline is arranged at the other end of the pipeline mixer and connected with the water distribution tank; a filter bed is arranged at one side of the water distribution tank; filter cloth is arranged on the filter bed; the two ends of the filter cloth are fixed on a first shaft roll and a second shaft roll; the first shaft roll is welded under the water distribution tank; and the second shaft roll is connected with a speed reducer. The device is reasonable in design, ingenious in connection, small in floor area, convenient to use and low in treatment cost, and does not need a relatively expensive membrane assembly.

Description

technical field [0001] The invention relates to a recovery and treatment device for surface treatment wastewater, which belongs to the technical field of wastewater treatment equipment. Background technique [0002] In the coastal area of ​​the Yangtze River Delta, there are many small and medium-sized surface treatment factories, including electroplating, painting, coating and other factories, which produce only a few tons of wastewater every day, and the layout of small factories is scattered, which is not conducive to the centralized treatment of sewage. With the development of the economy, the requirements for environmental protection are also increasing, and these waste water must be treated to meet the standards before they can be discharged. However, the recovery and treatment devices for surface treatment wastewater in the prior art are not only complex in structure, but also use reverse osmosis membrane modules. Due to the short service life of the reverse osmosis m...
