Wastewater resource utilization and zero discharge technologies are technologies such as pretreatment (biochemical method, physical and chemical method), membrane method ( UF , NF , RO , HERO , Hi-zero , DTRO , STRO ), evaporation crystallization ( MVR , MED ) and other technologies Carry out system integration, utilize resources produced by enterprises and achieve zero emissions. This technology has been successfully developed and used in Tiangang Group, Kaifeng Group, Bohui Paper and other enterprises, and has created good economic and social benefits.
This technology is a combination of international and domestic mature double-membrane technology, and performs corresponding pretreatment according to the water quality of raw water. In the design, it saves energy as much as possible, saves land, facilitates operation, and centralizes management and control. Or reclaimed water treatment station project.
