Tangshan Shengjie Environmental Protection Technology Co., Ltd. is a scientific and technological enterprise integrating research and development, engineering design and equipment manufacturing, focusing on the research and development of environmental protection equipment, focusing on the desulfurization and purification of coal gas, biogas and natural gas, and sewage treatment. Currently it is a well-known professional manufacturer of biogas and natural gas desulfurization purification equipment and sewage treatment engineering in China.
Pollutants in mine wastewater are mainly formed during the formation and mining process of the mine. In addition to the organic matter (humic acid), the wastewater is mainly suspended matter dissolved in the mining process. The comprehensive physicochemical treatment process method of dosing + cyclone precipitation + high density precipitation + advanced treatment . The purification process process determined based on this is shown in the block diagram above.
The process of the above-mentioned mine wastewater purification treatment process is as follows: the wastewater is pumped to the surface by a deep well pump and enters a regulating tank. PAC ，使污水和混凝剂进行 快速混合，混合后的废水接着进入涡流反应器进行絮凝凝反应。 After the regulation tank is collected, it enters the cyclone reaction precipitator from the regulation tank through the pipe mixer through the sewage lifting pump. PAC is added to the pipe mixer to make the sewage and the coagulant mix quickly. The device performs a flocculation reaction. The wastewater after coagulation reaction and preliminary sedimentation flows into the inclined tube sedimentation tank by itself. The inclined tube sedimentation tank uses the central water distribution method to enter the water. The water from the inclined tube sedimentation tank can meet the national discharge standards and be discharged.
After the sludge settled in the sedimentation tank enters the sewage collection tank, it is dewatered by the sludge treatment system before being transported.
