The Test Of Advanced Municipal Sewage Treatment By Coupling Technique Of AOPS, Efficient And Biomembrance Process

Adwanced municipal sewage treatment is a direct method to solve the water reuse problems.At present, although the Water Treatment Technology is to be relatively mature at home andabroad, kinds of pure methods all existed limitations. In this paper, the secondary wastewatertreatment about NH₃-N, P and COD producing Advanced oxidation, high adsorption andbiological membrane method combined depth processing. The aim is to explore acomplementary its short and multi-function efficient’s economic energy、 conservation andenvironmental protection water depth treatment technology.The paper studied Fenton’s operating conditions of dealing with NH₃-N, P and COD. Thispaper try to combine the advanced oxidation, high adsorption and biological membrane methodtogether to deal with the Ammonia nitrogen, Phosphorus and organic matter in secondaryeffluent from sewage plant.The main purpose is to find a complementary its short perfect depthprocessing mode.Through Fenton reagent’s static single factor test, determine the operating conditions ofFenton reagent: H₂O₂/Fe²⁺best molar ratio is15:1, pH is6. And when the shock strength is100r/min, it need to response20min. In the reaction conditions, the treatment effect ofphosphorus can reach90%, the removal rate of COD can reach50%. But Fenton reagent to theammonia nitrogen’s removal effect is not obvious, it is running at only10%. By comparing thehydrogen peroxide, iron vitriol and Fenton reagent static single factor test, Fenton reagent usedalone is better than hydrogen peroxide or iron vitriol used alone, and revealed the Fentonreagent’s removal mechanism.Based on the static adsorption material test research, screen out NH₃-N, P and CODpertinence adsorbent. Than the election results: Zeolite is to NH₃-N, Steel slag is to P andactivated carbon is to COD doing analyzed. Establish the adsorbents’ isothermal adsorptionmodel, and prove these models are all fit Freundlich Adsorption isothermal model. Thisillustrates these three kinds of adsorbents are multilayer adsorption, and the adsorption process ismore complicated. Though calculating, the quality of the steel slag, zeolite and activated carbonis1:4:10.Through the adsorption column, Fenton-adsorption column, biological adsorption column,Fenton-biological adsorption column thesefour combined modes doing the dynamic test research to deal with the Ammonia nitrogen, Phosphorus and organic matter in secondaryeffluent from sewage plant. After twenty days of test measurement and data analysis, determinethat the Fenton-biological adsorption column is the best mode to deal with NH₃-N,P and COD.The advanced oxidation, high adsorption and biological membrane method combined is a kind ofhigh efficiency, energy saving and good technology economic urban sewage depth processingmethod.
