Technical field
The present invention relates to nanofiltration and counter-infiltration sewage disposal system, more particularly to a kind of full-automatic nanofiltration and counter-infiltration sewage
Processing system.
Background technology
Nanofiltration is a kind of special and up-and-coming seperation film kind, and it is about 1 nanometer because of the size that can retain material
(0.001 micron) and gain the name, the operating range of nanofiltration between ultrafiltration and counter-infiltration, it retain organic matter molecular weight about
For 200~400 or so, the ability of retention dissolubility salt is between 20~98%, low to the removal efficiency of monovalent anion salting liquid
In high-valence anion salting liquid, the removal efficiency of such as sodium chloride and calcium chloride is 20~80%, and the removing of magnesium sulfate and sodium sulphate
Rate is 90~98%.Counter-infiltration is most accurate embrane method liquid separation technology, and it can stop that all dissolubility salt and molecular weight are big
In 100 organic matter, but hydrone is allowed to pass through, cellulose acetate reverse osmosis film salt rejection rate can typically be more than 95%, counter-infiltration
Composite membrane salt rejection rate be generally higher than 98%. they be widely used in seawater and brackish water desalination, boiler feedwater, industrial pure water and electronics
Prepared by level ultra-pure water, drinking pure water production, and the process such as wastewater treatment and special separation can using counter-infiltration before ion exchange
Operating cost and wastewater discharge is greatly reduced.
Current many sewage disposal enterprises, which combine nanofiltration with a point infiltration technology, forms nanofiltration and counter-infiltration sewage
Processing system, but nanofiltration and counter-infiltration sewage disposal system, front end must be provided with the pre-processing device of correlation, sewage carried out
Early stage is filtered, and can be only achieved expected purpose, and the scientific of early stage pre-processing device filtering influences later stage nanofiltration and counter-infiltration
Effect；In addition the science that nanofiltration pond and counter-infiltration pond are set also influences the effect of sewage disposal.
The content of the invention
