Description
Technical field
The present invention relates to water treatment agent field, particularly a kind of reverse osmosis antisludging agent.
Background technology
Reverse osmosis technology develops rapidly in China, has been widely used in industrial circle such as medicine production, electronics industry high purity water, water for beverages, Chemical Manufacture etc. at present.In the middle of the operation of counter-infiltration system, due to chemical contamination, colloid pollution and the very easily fouling of microbial contamination reverse osmosis membrane surface, this directly can have influence on the normal operation of reverse osmosis unit, and reverse osmosis membrane more can be made time serious to scrap.Solving counter-infiltration scale problems extensively adopts water inlet to add the method for antisludging agent, and therefore the exploitation of reverse osmosis antisludging agent is the focus that people competitively study always.
Current reverse osmosis antisludging agent is all containing a large amount of phosphate, due to the degraded of phosphorous water treatment agent after discharge, the Phos discharged will cause the eutrophication of water proximate, promote the growth of bacterium algae and will form " red tide ", bring huge harm to aquaculture and natural, ecological.And treatment effect is poor, and in composite use procedure, concentration is higher, is difficult to industrialization promotion and uses.
