Certain dense water must be discharged to certain multiple, and supplement new water.One 200,000 cool solidifying unit of KW, the circulating cooling water yield to reach
3.3 ten thousand tons/time about, it is assumed that in former water, salinity is 1000mg/L, and cycles of concentration is 3, then the concentration of recirculated cooling water row
Put about 6～about 8 ‰, i.e. 198～264m3/ h, needs the new water supplemented equal to draining and evaporation loss etc., amount of makeup water simultaneously
It is about the 2～2.6% of quantity of circulating water, will be 660～860m3About/h, water resources consumption is very with the quantity of sewage discharge
Big.
Frequently pole-reversing electroosmosis, is a kind of electrokinetics membrane separation technique.Driven by DC electric field, make the salt in former current
Class ion permeable ion exchange membrane enters concentrated stream, thus reaches the dual purpose that the desalination of former water concentrates with dense water.By controlling
Electric polarity fresh water stream and the periodicity auto-changing of concentrated stream, destroy newly-generated precipitation so that calcium, magnesium plasma and glue
Bodies etc. will not assemble fouling at face so that equipment can run steadily in the long term.The Multistage Membranes stack device that this utility model relates to
The Patent No. 2016200079376 submitted to State Intellectual Property Office for Dalian Jia Rui Environmental Protection Technology Co., Ltd, entitled
Multistage Membranes stack device disclosed in the patent application of " a kind of electrically driven (operated) film desalination unit ".
Electro-catalytic oxidation technology refers to utilize the direct oxidation of electrode and indirect oxidation effect to carry out catalyzing oxidizing degrading difficulty fall
Solve material so that it is be decomposed into degradable, the material of nonhazardous.Anode direct oxidation is owing to hydrone is put on the anode surface
Electricity produces OH group, OH group and the absorption Organic substance generation oxidation reaction on anode.Indirect oxidation refers to utilize electricity
The strong oxidizer that chemical reaction produces is (such as C1O–Deng) aoxidize Organic substance in solution.The electrocatalytic oxidation list of this utility model design
Unit is with inactive, conductive material as electrode and has supported the electrocatalytic oxidation unit of catalyst.
