Water Quality Characteristics

High-salinity and high-concentration organic wastewater is generally generated by the biochemical and biopharmaceutical industries. Its salinity is higher than 1%, and it has a large amount of organic pollutants that are difficult to degrade. The organics in this kind of wastewater are generally aromatic compounds and toxic organic solvents, and in the meantime, it also contains inorganic salts in high concentration, such as the Na+, Ca2+, Cl- and SO42+ ions, which have the characteristics of high hazardousness, bad biochemical quality and high difficulty for treatment, and it has become a global challenge that troubles the development of the chemical industry and the field of wastewater treatment.

Thought for Treatment

Treatment of the source: make efforts to recycle usable materials, and reduce the discharge volume of wastewater from the source;

Reduce cost: combine the advantages of the physicochemical and biologic methods, and adopt integrated process to reduce the cost of pure physicochemical process;

Choose appropriate pretreatment measures, and ensure effective continuity of the subsequent treatment.

Typical Treatment Process

Pretreatment—Anaerobic biochemical treatment—Subsequent aerobic treatment process

Technical Advantages

●Integrated iron –carbon Fenton reaction method, two-phase two-stage anaerobic method, high-efficiency composite filler;

●Compared with pure physicochemical process, by combining biological method for treatment, 1/2 cost can be reduced;

●Industrial waste materials are used as the filler, which have a high resource utilization rate, and also environment friendly and energy efficient;

●High-efficiency halophilic engineering bacteria are used as the advantage bacteria, which can adapt to the system environment in a short time. Under long-time operation, the system has a COD removal rate of (80~85) %, and the effluent has a stable water quality;

●The two-phase two-stage anaerobic method can increase the system stability and treatment efficiency in various stages, which is also easy for control;

●The filler has a biomass 3 times of the ordinary filler, the film forming time is reduced by 1/2, and the COD removal rate is increased by 10%;

●Resource utilization of the methane generated in the biochemical process can be conducted.
