Embodiment Construction

[0017] The specific embodiment of the present invention is described in detail below in conjunction with accompanying drawing of description:

[0018] See attached figure 1 , the wastewater discharged from the drum flows into the wastewater collection pipeline, and enters the grid through the action of the sewage pump. The flow velocity in front of the grid is 0.8m / s, and the flow velocity of the wastewater passing through the grid is 0.4m / s, effectively blocking large particles such as slag For insoluble substances, the waste water is roughly filtered.

[0019] The waste water flows out from the grid through the action of the sewage pump, and enters the collection pool through the sump. The sump is equipped with a temperature controller to adjust and control the temperature of the waste water at 30-50°C.

[0020] The waste water flows out from the collection tank, and under the function of the sewage pump, it enters the turbulent flow sedimentation tank through the heat pres...

Abstract

The invention provides a treatment device for reutilization of leather waste water. The treatment device for reutilization of the leather waste water comprises a rotary drum, a grating, a water collecting tank, a collection pond, a sand filtering pond and a turbulent flow settling pond, wherein the rotary drum, the grating, the water collecting tank, the collection pond, the turbulent flow settling pond are connected in sequence, the turbulent flow settling pond is further connected with a medicine adding system, and medicine added by the medicine adding system is prepared by the mixture of aluminum sulfate, ferric sulfate, magnesium sulfate and polyacrylamide. The treatment device and method for reutilization of the leather waste water have the advantages of being simple in operation, low in cost, easy to popularize, and capable of greatly reducing various pollution parameters.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment, and in particular relates to a leather wastewater reuse treatment device and method. Background technique [0002] With the rapid development of the leather industry in recent years, leather wastewater has become one of the important sources of pollution. According to statistics, at present, there are more than 20,000 large, medium and small leather factories in my country, and the annual wastewater discharge volume reaches 80-120 million tons, accounting for about 0.3% of the total industrial wastewater in the country. With the development of economy and society and the improvement of people's requirements for environmental protection, the treatment of leather wastewater has attracted more and more attention. [0003] At present, the treatment methods of leather wastewater mainly include: coagulation sedimentation method, adsorption method, catalytic oxidation method, etc. The coa...
