Abstract

The invention provides a full-quantification landfill leachate treatment system. The full-quantification landfill leachate treatment system comprises a pretreatment device, an evaporation device, a leachate advanced treatment device and a membrane treatment device, the pretreatment device is used for carrying out primary treatment on the landfill leachate; the evaporation device is used for carrying out evaporation treatment on the liquid which is primarily treated by the pretreatment device; the leachate advanced treatment device is used for carrying out demulsification treatment and decoloration treatment on condensate water discharged by the evaporation device; the membrane treatment device is used for filtering water produced by the leachate advanced treatment device; the invention further provides a treatment method adopting the treatment system. According to the invention, the landfill leachate sequentially passes through the pretreatment device, the evaporation device, the leachate advanced treatment device and the membrane treatment device, so that suspended solids, salts, grease and the like in the landfill leachate can be sequentially removed, the working efficiency of the membrane treatment device can be improved, and the service life of the membrane treatment device is ensured.

Description

technical field [0001] The invention relates to leachate treatment, in particular to a fully quantified landfill leachate treatment system and treatment method. Background technique [0002] A landfill is currently in the middle and late stage of closure, but the leachate adjustment pool has a large amount of water. There are currently three leachate treatment companies operating in the landfill, and two of them use DTRO (disk tube reverse osmosis) emergency concentration treatment. One adopts biochemical + membrane treatment process, and all three treatment companies have the problem of membrane concentration. In view of this situation, our company samples and analyzes the water samples of the on-site membrane concentrate, as follows: [0003] [0004] It can be seen from the above table that the landfill leachate has high COD, high ammonia nitrogen, high oil content, and has certain oxidizing properties. It has the following problems: [0005] 1. The traditional membra...
