Filtering system and method

Abstract

The invention relates to the technical field of environmental protection facilities, and provides a filtering system and method. The filtering system comprises a waste liquid clear liquid storage, a filter, a filtering screen storing box, a filtering screen recovering box and a press filter used for extruding and driving a first filtering screen; one end of the first filtering screen is rotatablymounted on the filtering screen storing box, the other end of the first filtering screen is rotatably mounted on the filtering screen recovering box, and the first filtering screen penetrates throughthe filter; the press filter is located in the filter, and the first filtering screen is mounted on the press filter; the waste liquid clear liquid storage communicates with the filter; and the filteris provided with a waste liquid inlet, and the first filtering screen is located under the waste liquid inlet. The filtering system can pretreat a penetrating fluid, thus the problems that disposingof an existing penetrating fluid or other waste liquid is low in automatic degree and high in disposing cost, and a spraying gun is prone to being blocked are solved, the types of the penetrating fluid or other waste liquid are not limited, adaptability is high, and the filtering system and method are suitable for industrial production occasions.

Description

technical field [0001] The invention relates to the technical field of environmental protection facilities, in particular to a filtering system and a method thereof. Background technique [0002] Treatment methods for landfill leachate or other waste liquids include physical, chemical and biological methods. The physical and chemical methods mainly include activated carbon adsorption, chemical precipitation, density separation, chemical oxidation, chemical reduction, ion exchange, membrane dialysis, gas and wet oxidation, etc. When the COD is 2000-4000mg / L, the physical and chemical method The COD removal rate can reach 50% to 87%. Compared with biological treatment, physical and chemical methods are not affected by changes in water quality and quantity, and the effluent water quality is relatively stable, especially for landfill leachate or other waste liquids that have a low BOD5 / COD ratio and are difficult to treat biologically. Effect. [0003] However, the cost of ph...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a fully automated filtration system to solve the problem of difficult filtration of leachate or other waste liquids, low degree of automation, easy blockage of spray guns, and atomization in the existing technology of denitration of leachate or other waste liquids. The problem of poor performance

[0006] Another object of the present invention is to provide a safe, high-efficiency, and low-cost filtration method to solve the high cost and low efficiency of leachate or other waste liquid disposal in the existing technology of using leachate or other waste liquid denitrification Leachate or other waste liquid problems such as odor and easy leakage
