AI Technical Summary

Technical Problem

In the prior art, the purification efficiency of raw skin pre-soaked water waste liquid is low, the oil is difficult to settle, and the adsorption system is high, resulting in expensive purification equipment.

Method used

The driving system is used to control the dissolved gas system to swing at the bottom of the purification tank, generate tiny bubbles to float the grease precipitate, and adsorb the liquid surface through the oil-fouling adsorption assembly. Combined with the quantitative module, the coagulant is controlled to achieve efficient separation and adsorption of grease.

Benefits of technology

It improves the efficiency of grease purification, reduces the difficulty of replacing adsorbent materials, realizes sewage treatment and its recycling, and reduces equipment costs.

Abstract

The invention provides a purification treatment system for raw hide pre-soaking water waste liquid, and relates to the technical field of wastewater treatment.The purification treatment system comprises a purification tank, a driving system, an oil stain adsorption assembly and a gas dissolving system.The top of the purification tank is in an open state, the waste liquid is injected into the purification tank from the top of the purification tank, and a coagulant is synchronously put into the waste liquid; the purification treatment system further comprises a quantification module, the quantification module is used for controlling the putting amount of a coagulant, the driving system is installed in the middle of the purification tank, the driving system controls the gas dissolving system at the bottom to swing along the bottom layer area of the purification tank, sediment generated after sedimentation can be extracted in the process, and the purification treatment effect is improved. The grease part is enabled to be concentrated towards the liquid level area from the upper area, so that the effect of efficiently adsorbing the grease is achieved, the purposes of more efficient sewage treatment and recycling are achieved, the difficulty of replacing consumables is reduced, and popularization and application of the environment-friendly technology are facilitated.
