Problems solved by technology

[0003] At present, the process control method of the leachate treatment system of the domestic waste landfill that has been built is simple and extensive. The control of the treatment system during the operation process generally adopts the method of manual sampling and testing, which is inefficient and takes a long time. It is difficult to treat the landfill leachate. The monitoring implemented by the system and the adjustment of system operating parameters lead to fluctuations in the raw water quality of landfill leachate inflow, or due to abnormal system operation without timely feedback, which often leads to system collapse or substandard water treatment.
