Landfill leachate treatment is the key object of national environmental supervision. From June 2021 to September 2021, according to the Yangtze River great protection and national environmental supervision requirements, the leachate treatment equipment of a waste incineration plant located in the upstream of the South-to-North Water transfer Project was upgraded.


(Ozone air floatation integrated equipment can handle 250t/d)

As a kind of high concentration organic wastewater, landfill leachate has complex composition. The pollutants COD, ammonia nitrogen, total nitrogen, chroma and heavy metals in water quality are high values. Improper treatment or operation of leachate will cause serious pollution to the surrounding environment, and it is also one of the most important sources of groundwater pollution. Because of the complexity of landfill leachate treatment is also a recognized problem in the field of water treatment.

Shenzhen Clear Technology Co., Ltd. uses the patented Dissolved landfill leachate process with CDOF-Cyclonic Dissolved OzoneFlotation Unit as the core technology, which overcomes the shortcomings of the traditional technology. It perfectly solves the problem of landfill leachate advanced treatment. (Ozone advanced oxidation swirl solution gas floatation integration technology for our invention patent)


CDOF technical features

Safety and environmental protection: fully closed with pressure operation, no ozone leakage risk;

Small footprint: the footprint is only 1/5 of the traditional equipment footprint;

Low operating cost: no concentrated solution is produced, no secondary treatment cost is increased;

Ozone utilization rate: up to 99%, exhaust basically no ozone taste;

Fast reaction time: catalytic reaction time is less than 15min, only 1/6 of the traditional equipment time;

Low energy consumption: using a variety of catalysts with pressure oxidation, heterogeneous and homogeneous, high catalytic efficiency (consumption is 1/2 of the traditional), low operating cost.

Up to now, the device has been running continuously for nearly four months, the running state is stable, the treatment effect is good and stable, and the treatment indicators are better than the design requirements. When the inlet COD1000mg/L is about (ultrafiltration produced water), the effluent COD200mg/L is about, the COD removal rate reaches 80%, the ozone dosage and COD degradation ratio is only about 0.8, and the overall effluent quality is better than the tertiary standard of Comprehensive Water Discharge Standard GB8978-1996. It fully meets the discharge requirements of the downstream sewage treatment plant. In addition, since the CDOF equipment was put into use, the biodegradability of sewage has been significantly improved, the water quality of downstream wastewater treatment plants has been significantly improved, and the COD discharge index has reached the class II standard of "Surface Water Environmental Quality Standard GB3838-2002", which has greatly reduced the pressure of downstream wastewater treatment plants. Because the project is located in the upstream of the South-to-North Water transfer project, the environmental protection requirements are very strict, the installation to ensure the stability of the water source, which is of great significance.


Advanced ozone oxidation cyclone dissolved gas floatation integrated device was successfully put into production, marking Keli you in the field of difficult municipal sewage treatment on a new level, further tamping Keli you adhere to the road of innovation and development, to create industry benchmark determination!

Shenzhen Clear Technology Co., Ltd. is a national high-tech enterprise focusing on the innovation and application of sewage treatment technology and committed to energy conservation and environmental protection. The company is determined to be a respected industry benchmark in the field of energy conservation and environmental protection.
