Embodiment Construction

[0022] The waste water diversion, separation, and quality treatment and utilization process method of the present invention, first separation and then treatment, diversion and pretreatment before separation to improve the concentration ratio, eliminate and reduce the possible harm to the reverse osmosis membrane, the main pollutants are only separated but not The purified water that removes and separates pollutants is reused, and the concentrated water from which pollutants are concentrated is further strengthened. The invention takes separation as a breakthrough to reduce, harmless and recycle waste water, and greatly reduces waste water treatment and discharge.

[0023] Taking electroplating wastewater as an example to illustrate the specific implementation example of the present invention:

[0024] With the development of the electroplating industry, the electroplating technology is becoming more and more mature, and electroplating has various plating types and various plat...

Abstract

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

Technical field [0001] The invention relates to a water purification technology in the field of environmental protection, in particular to a process method for waste water separation, separation and quality treatment and utilization. Background technique [0002] Wastewater treatment is the use of physical, chemical and biological methods to treat wastewater to purify wastewater and reduce pollution, so as to achieve wastewater recycling and reuse, and make full use of water resources. According to the source of its production, 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 chemical treatment), secondary treatment (biochemical treatment) and advanced treatment. Except for special pollution factors, wastewater treatment is generally mixed treatment. Electroplating wastewater is generally divided into pretreatment water, cyanide-containing wastewater, ...
