Industrial wastewater membrane treatment apparatus and use method thereof

Abstract

The invention discloses an industrial wastewater membrane treatment apparatus, which comprises a bottom plate, wherein four support rods are fixed on one side of the upper end of the bottom plate, a support plate is fixed on the upper ends of the four support rods, and is provided with a first opening, a precipitation box penetrates through the first opening position, and is fixed on the first opening position, four pad plates are fixed on the other side of the upper end of the bottom plate, a bearing rod is fixed on the upper end of the pad plate, a bearing rod is fixed on the upper ends of the four bearing rods, and is provided with a second opening, and a purifying box penetrates through the second opening position, and is fixed on the second opening position. The invention further provides a use method of the industrial wastewater membrane treatment apparatus. According to the present invention, the problems that the sewage cannot be completely treated, and the water resource is wasted due to the inability of the solid-liquid separation can be solved; and the sewage treatment is performed with the PW membrane so as to improve the efficiency, increase the organic load per unit volume, reduce the occupation area and completely purify the sewage.

Description

technical field [0001] The invention relates to the technical field of industrial wastewater treatment, in particular to an industrial wastewater membrane treatment device and a use method thereof. Background technique [0002] Biofilm method is a kind of wastewater aerobic biological treatment technology parallel with activated sludge method. It is a fixed membrane method, which is the artificialization and strengthening of the self-purification process of sewage water. It mainly removes soluble and colloidal substances in wastewater. Organic Pollutants. Treatment technologies include biological filters (ordinary biological filters, high-load biological filters, and tower biological filters), biological turntables, biological contact oxidation equipment, and biological fluidized beds. [0003] There are many reports about industrial wastewater treatment in the prior art. The patent of CN203269626U discloses a membrane treatment device for industrial wastewater treatment. ...

AI Technical Summary

Problems solved by technology

The patent of CN203269626U discloses a membrane treatment device for industrial wastewater treatment. The device not only has simple structure, low operating cost, convenient maintenance and management, but also has high water yield. However, it is found through research that the device cannot fully stir the sewage, making Insufficient reaction of sewage and chemicals

[0004] The patent of CN207973545U discloses a membrane separation device for treating industrial wastewater. The efficiency of harmful substance separation is improved through the cooperation of the first membrane module and the second membrane module, and the useful substances in the wastewater can be collected and reused through the use of the third membrane module. , however, it is found through research that the organic load per unit volume of the device is small and occupies a large area, which is inconvenient to use

[0005] The patent of CN207391206U discloses a multi-stage treatment device for industrial wastewater biofilm, which uses biofilm to perform multi-stage treatment of water, targeted and efficient multi-stage coordination treatment of wastewater treatment biofilm, and diversified and highly coordinated operations, but , when the device treats sewage, the solid-liquid separation is not complete, and the efficiency of sewage treatment is low
