摘要
垃圾渗滤液处理过程中产生的膜滤浓缩液处置是渗滤液处理行业的难题,实现浓缩液的全量化处理是最理想的解决方式.但是浓缩液中有机物、硬度、无机盐等会造成设备腐蚀结垢等,因此应设置相应的处理工艺.北方某市垃圾渗滤液浓缩液处理项目采用"预处理+蒸汽机械再压缩技术(MVR)蒸发+干化减量+焚烧协同"的处理工艺,出水水质能够达到设计标准,运行成本为295.32元/m3.项目的稳定运行实现了园区浓缩液的全量化处置,具有推广应用价值.
Abstract
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.
