Integrated liquid treatment device

Abstract

The invention provides an integrated liquid treatment device. The integrated liquid treatment device comprises a liquid inlet pipeline, a liquid outlet pipeline, a plurality of cavities surrounded from inside to outside and isolated from each another, filter mediums, baffling bodies, an oil-water separation unit and liquid discharging ports, wherein the multiple cavities comprise first cavities, second cavities and third cavities; the filter mediums are arranged in the first cavities and are located downstream of the liquid inlet pipeline of a liquid flow path; the baffling bodies are obliquely arranged in the upper parts of the second cavities and provided with through holes, the baffling bodies on the lower parts of the through holes and the side walls of the first cavities form a spacefor accommodating liquid, and oleophylic hydrophobic films are arranged on the through holes; overflow ports are formed in the walls, close to the second cavities, of the first cavities, and the through holes face the entered liquid through the overflow ports; the liquid in the second cavities enters the third cavities through the oil-water separation unit; the liquid in the third cavities overflows and enters the second cavities through the through holes; and the liquid discharging ports are formed in the side walls and / or baffling bodies. The integrated liquid treatment device has the advantages of compact structure, small size and the like.

Description

technical field [0001] The present invention relates to liquid separation, and in particular to an integrated liquid treatment device. Background technique [0002] Industrial oily wastewater contains organic substances harmful to the environment such as oil, surfactants and organic additives, so it cannot be discharged arbitrarily without treatment. Industrial oily wastewater is recycled after oil-water separation or discharged after treatment up to standard, which are all environmental protection measures for industrial oily wastewater treatment. Machining cutting fluid is a metalworking fluid used for cooling and lubricating during metal cutting, cutting, grinding and other processing processes. It has a wide variety and complex composition, usually including base oil, emulsifier, antirust agent and so on. Cutting fluid has the functions of cooling, lubricating, cleaning and rust prevention during the processing of metals and their alloys. The waste cutting fluid used i...

Problems solved by technology

When removing miscellaneous oil, the method of manually adjusting the liquid level of the U-shaped tube is adopted. When the equipment is running, the staff needs to be on duty to facilitate the timely removal of oil from the oil-water separator. , the discharged oil more or less carries waste liquid

Although the steel belt degreasing machine can realize automatic degreasing, the degreasing effect of the steel belt degreasing machine is poor, the treatment efficiency is low, and the discharged oil also carries too much waste liquid
