Technology introduction:
According to the requirements of environmental sensitive areas, the fracturing flowback fluid is discharged on-site, and the special catalyst RSD-06 for advanced catalytic oxidation is innovatively developed.Research and development of coagulation-advanced catalytic oxidation process, integrated module skid-mounted effluent treatment device, forming the fracturing flowback fluid effluent standard treatment technology.
The technical problem of deep degradation of intractable organic matter has been solved, and the external discharge of fracturing flowback fluid in shale gas or tight oil development has been guaranteed to meet environmental protection treatment and safe disposal standards.

Technology characters：
1、Developed high-performance HJ - Ⅲ, r&d compound coagulant coagulation technology, suspended matter, oil especially organic matters, such as calcium and magnesium ions removal effect is remarkable.
Coagulation parameters：pH9～10、Add coagulant 2～8g/L、HPAM为5ml/L
treatment effect：COD removal rate ＞86%；Total hardness removal rate＞86%
2、Innovative development of catalytic oxidation process - to achieve the standard of organic discharge treatment。
The special catalyst RSD-06 was independently developed, and the industrial independent production was realized. The catalyst supported more active substances, large specific surface area, and strong ability of synergistic ozone degradation of organic matter。
3、Innovative integrated discharge processing device。
Innovative development of the industry's first set of advanced oxidation tower, coagulation equipment - pipeline mixer。
Field application：
After the application of effluent technology, the water quality can meet the discharge standard and realize the safe disposal.
More than 35,000 cubic meters of returned liquid have been treated on site, and the water quality has reached the national sewage discharge standard.The effluent treatment technology has the advantages of good effect, simple process, less dosage, green and efficient.
