Adsorption-deoiling water tank

Abstract

The invention discloses an adsorption-deoiling water tank. The adsorption-deoiling water tank is applied to a deep treatment system of industrial oily wastewater, is connected between oil-water separating equipment and filtering equipment in series and is used for strengthening a deoiling effect; the adsorption-deoiling water tank is divided into two grids which are used in series, i.e., an oil and water separating chamber and a clear water chamber; a pocket is arranged on the water surface of the oil and water separating chamber in a floating manner, and efficient oil absorbent cotton, whichonly adsorbs fats and oils and does not absorb water, is filled in the pocket; the oil and water separating chamber communicates with the clear water chamber; and water passing through the oil-water separating equipment enters the oil and water separating chamber firstly and then enters the clear water chamber through a water through hole, and a water absorption pipe of a filter pump absorbs waterfrom the deoiled clear water chamber in a subsequent treatment process. The adsorption-deoiling water tank is simple and practical and is free of secondary pollution; and after deoiling by the adsorption-deoiling water tank, the rate of deoiling of yielding water is close to 100%, and thus, the probability of blockage to subsequent deep-treatment filtering equipment can be lowered greatly.

Description

technical field [0001] The invention is applicable to the field of industrial waste water degreasing, and relates to an oil-water separation facility for advanced treatment of residual grease after conventional degreasing treatment of industrial oily waste water, specifically an adsorption degreasing water tank. Background technique [0002] The floor of workshops or sheds in automobile dismantling workshops, mechanical production and processing plants often has oil stains. After washing the ground with water, oily wastewater is produced. The components of oily wastewater in these oily wastewaters are usually water-insoluble motor oils and lubricating oils. [0003] With the continuous improvement of environmental protection standards and requirements, national and local comprehensive sewage discharge standards have given stricter regulations on the oil content of sewage discharged into municipal sewage pipe networks and discharged into natural water bodies. Taking Tianjin l...

AI Technical Summary

Problems solved by technology

[0004] In the treatment of oily wastewater, the density difference between oil and water is usually used, and conventional gravity treatment methods such as dosing demulsification, dissolved air flotation, and heating air flotation are used to separate oil and water, and the removal rate of oil can reach 90-98%; If the oil content of the effluent after conventional treatment is still not up to the standard, and the filter equipment for subsequent advanced treatment adopts activated carbon filter with small pores or various membrane filter equipment, the filter equipment will be easily blocked by residual oil and affect its service life
