With regard to it is domestic at present in the Coal Chemical Engineering Project of operation for, existing two to three realize the " useless of Coal Chemical Engineering Project
Water zero discharge ", but equally exist major defect;For the Inner Mongol project of successful operation, have been realized in
The output of crystal salt.But the mother liquor discharged for crystallization apparatus is not well solved but.What the current project was taken
Measure is to direct cycle to mother liquor in front end system, causes plurality of impurities to be enriched with, fluctuation of service, reclaims condensate liquid water quality and reaches
Mark is difficult, while output crystal salt is brown, the phenomenon such as salt component is impure, it is impossible to complete the recycling of moisture and solid salt.This
If kind of a situation cannot rationally improve, while being impacted to environment, the economic benefit of factory can be also had a strong impact on.
For the crystalline mother solution of coal chemical industrial waste water, more safe processing mode is carries out burning disposal at present.But by
Salt content is very high in coal chemical industrial waste water crystalline mother solution, and the characteristics of particularly chloride ion content is higher causes incinerator
Equipment material is higher, and investment cost is greatly promoted;Simultaneously because containing substantial amounts of COD impurity in crystalline mother solution, to avoid burning
During produce the formation secondary pollution of the noxious material such as bioxin, therefore cause the operation operating mode of incinerator extremely harsh, pole
The big operating cost for adding device.Therefore either investment cost, or operating cost, all serious limits burning work
Application of the skill in the disposal of coal chemical industrial waste water crystalline mother solution.
