Description
The present invention is application No. is 201510980936.X, and the applying date is on December 23rd, 2015, and applying type is invention,
Apply for a kind of divisional application of the minimizing processing method of entitled high slat-containing wastewater.
Technical field
The present invention relates to industrial wastewater treatment device fields, more particularly to one kind is based on during high slat-containing wastewater minimizing
Water inflow control system.
Background technology
In recent years, it with the fast development of the industries such as petrochemical industry, electric power, metallurgy, coal chemical industry, is generated in industrial processes
The sewage quantity of the saliferous complicated components such as reverse osmosis concentrated water, trade effluent, circulating sewage and some processes draining increases year by year, this
How the sewage of a little saliferous complicated components finally handles and using receiving extensive attention.As country is to enterprise's sewage discharge
Control dynamics are increasingly stringent, and especially in water resources shortage area, it is multiple containing salt component how rationally to handle and make good use of this part
Miscellaneous sewage is realized wastewater zero discharge, the surrounding enviroment and natural water that we depend on for existence to protection, and is further increased
The comprehensive utilization ratio of water resource alleviates water resource pressure and is of great significance.Currently, in waste water treating and reutilizing technology, instead
Infiltration embrane method has been increasingly becoming a kind of extremely important processing in the fields such as industrial circulation water treatment, waste water recycling, minimizing
Means.
Reverse osmosis technology development ratio currently used for handling waste water is very fast, but existing for the technical finesse complicated ingredient waste water
Problem is increasingly prominent, and main problem shows two aspects：
