Landfill Leachate Wastewater Management System , Wastewater Treatment Unit PH Adjustment

High Automation Landfill Leachate Treatment System PH Adjustment

Background:

The treatment of leachate from municipal landfills has been a very difficult problem in landfill design, operation and management. Leachate is the product of gravity flow of liquid in landfills, mainly from precipitation and internal water content of the waste itself. The nature of the leachate varies over a considerable range due to many factors in the flow that may affect the properties of the leachate, including physical, chemical, and biological factors.

Generally, the pH value is between 4 and 9, the COD is in the range of 2000 to 62000 mg/L, and the BOD5 is from 60 to 45,000 mg/L. The concentration of heavy metals is substantially the same as the concentration of heavy metals in municipal sewage. Municipal landfill leachate is a high-concentration organic wastewater with complex composition. If it is discharged into the environment without treatment, it will cause serious environmental pollution.

Process flow chart:

Process Description:

The landfill leachate treatment process includes wastewater treatment, coagulation air flotation or sedimentation, ammonia nitrogen stripping, biochemical treatment, pH adjustment, microwave oxidation, neutralization and flotation, filtration and discharge, etc.

The treatment part adopts the biological enzyme technology and the deep oxidation treatment part adopts the microwave oxidation technology, which improves the treatment efficiency of the biological treatment part, reduces the sludge reflux process, and does not produce concentrated liquid after the advanced treatment, and has no secondary pollution, so that the landfill leachate Processing costs are reduced.

Field equipment picture :

Supply (cooperation) mode and delivery cycle

1: Determine the usage scenario.

2: Analyze the quality of contaminated water (if necessary, do laboratory analysis)

3: Determine the treatment process.

4: The supplier forecasts the price duration and governance objectives of the equipment or system.

5: The supplier and the buyer negotiate the price duration and the governance objectives, negotiate the contract, and sign the contract and pay the supplier prepayment.

6: After the equipment is produced and paid by the buyer and its agent, the payment will be made.

7: The supplier rushed to the place of use of the buyer for installation instructions and commissioning.

8: System training for equipment use and maintenance.

Advantages: good effluent water quality, stable water discharge, flexible operation, small floor space, high automation, easy operation and mobility, and strong mobility.
