Brief introduction

Source:

The moisture of the garbage; The rain and snow water in the landfill;A kind of high concentration organic wastewater formed after removing the saturated water capacity of the garbage and the overburden layer, and experiencing the garbage layer and the overburden layer; Accumulated water leakage from garbage used for incineration.

Characteristic:

There are many kinds of organic pollutants and high concentration of COD; the biodegradability and nitrification of landfill leachate are poor, especially the NH3-N concentration of "aged" leachate is very high, and the B / C and C / N are very low.

For the environment:

High concentration of organic matter, complex pollution components, high toxicity, difficult degradation, and complex water quality are easy to have destructive effects on water and soil.

Technical process

After pre filtration, the wastewater enters the low-temperature evaporator and evaporates under vacuum and low-temperature conditions. The water vapor condenses and forms distilled water in the process of vacuumizing, which is collected into the clean water barrel; the remaining residue in the distillation kettle is collected into the barrel for further treatment. It can greatly reduce or even remove the harmful chemicals and heavy metals contained in the waste liquid. The evaporation rate of the equipment can reach more than 60%. Through the pre-treatment and post-treatment process, the effluent water quality is clear and transparent, and the biochemical property of wastewater quality, reclaimed water reuse or discharge standard are realized.
