The Research And Feasibility Of A/B(B Is A/O) System For Leachate

The quality and quantity of water was studied, and the typical water sample was confirmed. The process and research of leachate treatment were analyzed, and all the methods were compared, found that after the pretreatment, commix leachate and town wastewater for a co-treatment was feasible. The experiment used the A/B(B is A/O biological denitrification ) system for leachate treatment ,the efficiency and the stabilization were studied. The results showed that the co-treatment can overcome the problem of C(COD),N(TN) and P maladjusted, which was a restrict of the NH₄⁺—N and TN treatment, and the results was COD<1200mg/L, BOD₅<30mg/L, NH₄⁺—N<15mg/L, TKN<30mg/L, which conform to the Integrated Wastewater Discharge Standard and the Standards for Irrigation Water Quality. The feasibility of A(oxygen deficient actived sludge)/B(A/O biological denitrification ) system for leachate treatment was analyzed, and it also fit for the development of town.
