Description
Technical field
It is useless that the present invention relates to the high saliferous of one of field of industrial waste water treatment more particularly to zero discharge of industrial waste water technology
The minimizing processing method of water.
Background technique
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 is 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 realizes wastewater zero discharge, to the surrounding enviroment and natural water for protecting us to depend on for existence, and further increases
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 the extremely important processing in one of 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 treatment complicated ingredient waste water
Problem is increasingly prominent, and main problem shows two aspects:
First is that reverse-osmosis membrane element has equipment with high desalinization to brine waste, reverse-osmosis membrane element be can achieve under normal conditions
Salt rejection rate 98% or more so that do not undergo phase transition 98% or more salt and impurity in water be trapped in system generation concentrated water
In.The recovery utilization rate of the reverse osmosis general water of water manufacturing system can only achieve 75% or so, and water manufacturing system still has about 25% concentrated water
It cannot recycle and need to discharge.Due in the concentrated water of these saliferous complexity waste water containing including a large amount of calcium ions, magnesium ion, again
Metal ion, silicon ion and colloid substance, also, some wastewater from chemical industry contain a fairly large number of nondegradable organic matter
With inorganic salts and the complicated ingredient closely related with production technology, direct emission can cause water pollution to the river being discharged into.
Although reverse osmosis treatment realizes a degree of minimizing processing, the salts substances of concentration are remained in the concentrated water of exclusion,
Outlet or direct emission after simple process are generally used to such wastewater treatment method at present, surrounding enviroment are influenced increasingly tight
The disposition of weight, this final part reverse osmosis concentrated water is a problem.
Second is that the saliferous complexity waste water by low pressure, medium and high pressure reverse osmosis concentration, recycles reverse osmosis treatment mode
Fouling easily occurs in film surface with the inorganic salts calcium and magnesium compound for tending to saturation there are the organic pollution of membrane component when processing to ask
Topic.To lead to the problems such as salt separating difficulty increases and separating energy consumption increases, and economy is bad and reliability is lower.

The cleaning of acid, alkalinity, bleaching and oxidating chemicals is born, the microfiltration membranes membrane tube through over cleaning has longer validity period.The hair
Bright process CIMS is simple, operates more convenient, automation control easy to accomplish；Occupied area is small, can save basis
The investment of construction period, but also medicament investment can be saved.But the system only carries out pretreatment and reverse osmosis place to waste water
