Problems solved by technology
During the membrane filtration process, the ultrafiltration membrane intercepts pollutants such as particles and colloids in the water, and accumulates on the surface or pores of the ultrafiltration membrane, which adversely affects the ultrafiltration process.

Belonging to the sewage treatment field, the invention discloses a metal surface treatment wastewater purification device. The device includes a membrane treatment tank for treating metal surface treatment wastewater, the membrane treatment tank is internally equipped with a multi-segment structure hollow suction main pipeline, which includes a first pipeline, a second pipeline and a third pipeline that are communicated sequentially, and the first pipe and the membrane treatment pipe are connected sequentially. The first pipeline is in fixed connection with the membrane treatment tank and is communicated with a suction water pump, the second pipeline is a corrugated expansion pipe, the third pipeline consists of a horizontal section and a vertical section that are communicated with each other, the horizontal section is in fixed connection with the second pipeline, the vertical section is communicated with a plurality of hollow ultrafiltration membrane filter pipes in parallel arrangement, a support seat is disposed at two ends of the vertical section in the third pipeline, and does straight reciprocating motion under the action of first power sources. The device has the advantagesof increasing the tangential flow velocity of the ultrafiltration membrane surface, reducing the pollutant layer thickness and improving the mass transfer coefficient, and is suitable for purificationof metal surface treatment wastewater.
Description
technical field [0001] The invention relates to the field of sewage treatment, in particular to a metal surface treatment wastewater purification device. Background technique [0002] The wastewater discharged by metal surface treatment enterprises contains a large amount of ammonia nitrogen, organic nitrogen, inorganic and organic phosphorus, heavy metals, COD (mainly refractory organic matter), etc. The composition of the wastewater is very complex and its biodegradability is extremely poor. At present, it is still very difficult for the nitrogen, phosphorus and heavy metals in the discharge water of most metal surface treatment enterprises to meet the requirements of the "Discharge Standard of Pollutants for Urban Sewage Treatment Plants" (GB18918-2002) level 8 standard. [0003] When the pressure of the ultrafiltration membrane in the membrane treatment pool is constant, the membrane flux decreases with the extension of the filtration time; under the condition of a const...
