Application and Case Analysis of Landfill Leachate Pretreatment in a City
As the water quality of leachate in a municipal landfill site is complex and changes greatly,it is difficult for the existing leachate treatment equipment to discharge stably after treatment to meet the standards.Therefore,this paper aims at the current leachate treatment status,incoming and outgoing water quality and current treatment process flow of the landfill site,and optimizes the process.By adding a set of pre-treatment system,the leachate treatment capacity is improved.It is found that after 15 days of operation after process optimization,the pre-treatment system runs stably,and the effluent of the total treatment system can be discharged stably up to the standard.Finally,in view of the problems existing in the operation process,suggestions for further development of landfill leachate treatment are put forward.
