Landfill leachate treatment

We provide development, system integration and technical services of landfill leachate treatment equipment to meet customers’ needs for landfill leachate treatment, in which the complete sets of equipment can realize the treatment of landfill leachate through technologies such as “MBR+NF+RO”, “MBR+Advanced Oxidation+Enhanced Biochemistry”, “Two-stage DTRO”, “Two-stage DTRO+MVR”, “Pre-treatment+MVR”, etc. MBR+NF+RO”, “MBR+Advanced Oxidation+Enhanced Biochemistry”, “Two-stage DTRO”, “Two-stage DTRO+MVR”, “Pretreatment+MVR” and other technologies to realize the full quantitative treatment of leachate from the landfill, and the specific equipment can be used for the treatment of landfill leachate. The specific process flow and examples of actual cases are as follows:

Project Profile

This project is the environmental health management office of the domestic waste disposal management center concentrate treatment project, the treatment object for NF, RO membrane concentrate, design scale 80t / d, put into operation at the end of 2021, the water production indexes to GB16889-2008 Table 2 standards.

Process

This project adopts the combined process of “chemical softening and hardness removal + DTRO reverse osmosis membrane concentration + MVR evaporation + volume reverse osmosis” to carry out full quantitative treatment of concentrated liquid. Concentrate produced by the front-end traditional process unit “biochemical + membrane treatment” is collected and pumped to the “chemical softening + membrane separation” processing unit, after removing calcium and magnesium hardness, it is concentrated by DTRO under high pressure, and the concentrate enters the MVR forced circulation evaporation system for further treatment.
