Design and Case Analysis of Fully Quantitative Treatment Process for Leachate From a Domestic Waste Landfill
Taking the full quantitative treatment project of leachate from a domestic waste landfill of suzhou as an example,combining the water quality characteristics and discharge requirements of the project's leachate,this pa-per designs a combination process system of"Pretreatment+DTRO+Forward osmosis+Evaporation".The practice has proved that the combination process system has achieved significant results and the effluent meets the relevant national standards and requirements after treated by this process,which has good environmental benefits and can operate efficiently,stably,and continuously.The overall water production rate has reached 97%,with re-moval rates of CODcr,NH3-N,TN,TP and salt exceeding 99.9%,and SS removal rate reaching 100%.The pur-pose of this paper is to guide the operation of other comprehensive treatment projects of leachate from domestic waste landfills.
