High-Salt Landfill Leachate Treatment
1) Project information:
Location: Kaizhou District, Chongqing
Project: Advanced treatment of high-salt landfill leachate
Installation date: 2020.7
2) Introduction to the basic situation
Tus-Environment (stock code: 000826), a subsidiary of Tus-Sound, Chongqing Kaizhou: Domestic waste incineration power plant, mixed wastewater adopts "regulating tank→coagulation sedimentation tank→UASB reactor→membrane bioreactor (MBR)-nanofiltration membrane (NF) system" has achieved the design effect. In order to improve the discharge quality, the RO system is used to further treat the wastewater.
The wastewater quality is as follows in Table:
Testing Index | COD | Turbidity NTU | SDI15 | TDS（mg/L） | Conductivity（us/cm） |
Value | 58 | 5.1 | 4.9 | 17821 | 21356 |
Wastewater Index
3）Index after RO system treatment
Testing Index | COD | Turbidity NTU | SDI15 | TDS（mg/L） | Conductivity（us/cm） |
Value | 12 | 0.1 | 0.1 | 219 | 381 |
Permeate water Index
The analysis concluded that after customers use HITON environmental protection reverse osmosis membrane elements, the treatment of wastewater has achieved the expected results.
