Abstract

The invention discloses an industrial waste water recycling process. A sewage pretreatment unit, an MCR (Membrane Coagulation Reactor) treatment unit and an RO (Reverse Osmosis) treatment unit which are connected in sequence are adopted. The industrial waste water recycling process comprises the following steps: pretreatment: introducing industrial waste water into the sewage pretreatment unit, removing cyanogen in water through an oxidizing or reducing method, and removing a complex in water through a de-complexing agent; MCR treatment: introducing the pretreated sewage into the MCR treatment unit, adding PAC (Poly Aluminum Chloride) into a pre-posed coagulation reaction pond in the MCR treatment unit to perform a coagulation reaction: RO treatment: introducing the effluent subjected to the MCR treatment into the RO treatment unit to perform reverse osmosis deep treatment to obtain recycled water. In the process, the MCR treatment is performed before the RO treatment, so that the quality of the water in the RO treatment unit is ensured, damage to an RO membrane component is reduced, and the reaction speed is increased; the industrial waste water recycling process can be applied to the field of industrial waste water treatment.

Description

technical field [0001] The invention relates to the field of industrial wastewater treatment, in particular to an industrial wastewater treatment and reuse process and a system thereof. Background technique [0002] The total amount of water resources in China is 2.81×10.4 billion tons, and the per capita fresh water possession is only 1 / 4 of the world average. It is one of the 21 water-poor and most water-deficient countries in the world. More than 400 of the more than 600 state-owned cities have insufficient water supply, and 110 cities are seriously short of water. With the development of regional economy, the demand for water in cities continues to grow, and the supply of water resources is insufficient. The low efficiency of water used in industrial production and the low rate of reuse lead to high costs and reduced benefits of output value. The GDP output of unilateral water is 1 / 3 of the world's average level. The utilization rate of agricultural water is only 40% t...
