Abstract

The invention provides a system for recycling waste water containing oil and washing water. The system comprises a waste water collection pool, a lift pump, a flocculating agent feeding device, an air lift flow reduction type reactor and an inner circulation system, wherein the waste water collection pool, the lift pump, the air lift flow reduction type reactor and the inner circulation system are sequentially connected with one another through pipelines; the flocculating agent feeding device feeds a flocculating agent into the pipeline between the lift pump and the air lift flow reduction type reactor; waste water containing the oil and the washing water sequentially flows through the waste water collection pool, the lift pump, the air lift flow reduction type reactor and the inner circulation system and then is purified; and the purification efficiency is high, and the process is simple.

Description

technical field [0001] The invention relates to a water treatment system, in particular to a recycling system for waste water containing oil and washing. Background technique [0002] my country is a country with a shortage of water resources, and there are varying degrees of water shortages in many places. Therefore, the comprehensive utilization of domestic and production wastewater is more important. The air flotation method to purify production wastewater and domestic sewage is a newer water treatment technology in the world. The principle of treatment technology is to introduce a large number of tiny air bubbles into the wastewater, and the air bubbles adhere to the fine suspended matter through the effect of surface tension, forming a situation where the overall specific gravity is less than 1, and float to the water surface according to the principle of buoyancy, so as to realize solid-liquid or liquid-liquid separation . [0003] The traditional treatment process of o...
