Abstract

The invention discloses a composite resin adsorbent for copper pollution in municipal sewage and a preparation method of the adsorbent. The adsorbent comprises the following components, by weight part, 30-40 parts of a modified resin, 10-15 parts of a pseudomonas xiamenensis CGMCC No. 1.6446 biomembrane, 5-8 parts of polymeric phosphate-ferric chloride, 5-8 parts of sodium tripolyphosphate, 2-6 parts of sodium metaaluminate and 0.4-0.8 part of sodium dodecyl sulfate. Through the adsorbent, physicochemical indexes of the composite resin adsorbent for copper pollution in municipal sewage can achieve the GB18918-2002 standard and the contents of COD, BOD, SS and copper ions can be effectively reduced. The adsorbent is simple in processing technology, less in consumption, excellent in processing effect and stable in performance. The adsorbent provides effluent with good quality, enables cost for water treatment to be effectively reduced, and brings great economic benefit and social benefit.

Description

technical field [0001] The invention relates to the technical field of sewage treatment agents, in particular to a composite resin adsorbent for copper pollution in urban sewage and a preparation method thereof. Background technique [0002] Heavy metal content in urban sewage often exceeds the standard. At present, there are physical, chemical, and biological methods to treat copper pollution in urban sewage, but most of the physical methods have poor treatment effects and unstable treatment rates; biological methods are too expensive to be popularized and used; more chemical methods are used. method to treat sewage, but the existing sewage treatment agent has secondary pollution problems in its reagent components, which will also have a certain impact on the environment. Contents of the invention [0003] The object of the present invention is to provide a composite resin adsorbent for copper pollution in municipal sewage and a preparation method thereof, so as to solve...
