Embodiment Construction
[0023] The waste water separation, separation and quality separation process of the present invention utilizes the process method, which first separates and then treats. Before the separation, the flow is divided and pretreated to increase the concentration ratio, eliminate and reduce possible damage to the reverse osmosis membrane, and the main pollutants are only separated and not removed. Removal, separation and reuse of clean water from pollutants, and intensive treatment of concentrated water from pollutants. The invention takes separation as a breakthrough point, reduces waste water treatment, makes it harmless and recycles, and greatly reduces waste water treatment and discharge.
[0024] Taking electroplating wastewater as an example to illustrate the specific implementation of the present invention Embodiment one:
[0025] With the development of the electroplating industry, the electroplating technology is becoming more and more mature. There are various plating type...

The invention relates to a wastewater split-flow separation and quality-based treatment utilization process method. Wastewater is subjected to split-flow into high-concentration waste liquid and low-concentration clean water; the low-concentration water is simply pretreatmented, and is subjected to reverse osmosis separation into fresh water and concentrated water; the resource utilization of fresh water is realized; the quality-based treatment is performed for utilizing concentrated water, so that the wastewater treatment realizes reduction, harmlessness and recycling. The defects of complexity, long flow process, great consumption, serious secondary pollution and the like of the existing wastewater treatment process are overcome. The process method is suitable for treatment and utilization of various kinds of low-salinity industrial wastewater and municipal domestic sewage.
Description
[0001] Technical field [0002] The invention relates to a water quality purification technology in the field of environmental protection, in particular to a waste water diversion, separation, quality separation, treatment and utilization process method. Background technique [0003] Wastewater treatment is the use of physical, chemical and biological methods to treat wastewater, purify wastewater, reduce pollution, and achieve wastewater recovery and reuse, making full use of water resources. According to the source of its generation, it is divided into industrial wastewater treatment and domestic sewage treatment, and according to the treatment level and effect, it is divided into pretreatment (physical and chemical treatment), secondary treatment (biochemical treatment) and advanced treatment. Except for special pollution factors, wastewater treatment is generally mixed. Electroplating wastewater is generally divided into pretreatment water, cyanide-containing wastewater, ...
