Design and Application of Full Quantitative Disposal of Concentrated Leachate in a Northern City
The disposal of membrane filtration concentrate generated during the leachate treatment process is a difficult problem in the leachate treatment industry,and it is the most ideal solution to achieve full quantification treatment of concentrated leachate.However,the organic matter,hardness and inorganic salt in the concentrated liquid would cause corrosion and scaling of the equipment,so the corresponding treatment process should be set up.The concentrated leachate treatment project in a northern city adopted a treatment process of"pre-treatment+steam mechanical recompression technology(MVR)evaporation+drying reduction+incineration synergy".The effluent quality could meet the design standards,and the operating cost was 295.32 yuan/m3.The stable operation of the project had achieved the full quantitative disposal of concentrated leachate in the park,and has the value of promotion and application.
