        CASE
        GT-D03 application case - high oil content cleaning wastewater treatment case
        The company is mainly engaged in the business such as production of metal products, plastic products, cleaning waste water produced in the process of its production and processing, high oil high COD, the characteristics of raw water COD in 24000 ~ 30000 m
        Description
        A case study of high oil content cleaning wastewater treatment of a company in shenzhen
        1 corporate reality
        The company is mainly engaged in the business such as production of metal products, plastic products, cleaning waste water produced in the process of its production and processing, high oil high COD, the characteristics of raw water COD in 24000 ~ 30000 mg/L range, and the high degree of emulsification, containing a large amount of surfactant, cause great load to biochemical treatment, COD exceeds bid for a long time, wastewater discharging standard has yet.
         
        2. On-site problems
        Original process cleaning and fenton after every oil wastewater treatment, after treatment of COD in 2500 ~ 4800 mg/L range, processing operation effect is unstable, and fenton reaction complex operation, storage and use of hydrogen peroxide has a certain risk to the operator, before and after the reaction of acid alkali increase operator's work, after the reaction produces a large amount of oily scum need further fished scraping mud, mud, operation and oil residue is difficult to squeeze in press machine. After finton treated wastewater is treated with ferrous iron, calcium chloride and PAM, the concentration of organic pollutants and surfactant entering the biochemical tank is still very high, resulting in a large amount of foam on the surface of the biological contact oxidation tank, and the COD of the biochemical effluent is in the state of 400 to 800 exceeds the standard for a long time.
         
        3. Wastewater treatment
        The daily treatment water is 8m, the COD of the inlet water is 24,000 ~ 30,000 mg/L, and the original fenton reaction tank is used as the demulsifying coagulant tank.
        Process flow:


        4. Problem solving
        Raw water after every except the oil slick by our efficient sewage treatment medicament GT - D03 demulsification coagulant, macromolecular organic pollutants (pops) such as the vast majority of oil to water and some surfactants removal, raw water COD greatly reduced to 1200 to 1400 mg/L, removal rate of 95%, greatly enhance the system before handling capacity, great stability to reduce subsequent biochemical load. Simplify complexity, improve efficiency, no fenton, more stable than fenton.
        After a week of high-efficiency agent operation, the biochemical system gradually recovered from the previous long-term high-load operation, and the biochemical treatment capacity was gradually improved. The COD effluent reached the factory's ≤80mg/L standard, and finally reached ≤50mg/L. It not only solves the urgent need of enterprises, but also solves the increasingly severe environmental protection problems faced by enterprises in the long run.
         
        5. Product advantages
        Gt-d03 demulsifying coagulant is a highly efficient sewage treatment agent developed and produced by our company. It belongs to the non-polar polymer graft copolymer, with unique chemical structure and arrangement. After adding waste water, it can play the role of interparticle adsorption bridging and electric neutralization, condense emulsified oil and colloid in waste water and separate and precipitate, with excellent functions of oil removal, decolorization and COD removal. The removal speed is very fast, can completely remove the oil colloid, the formation of alum flower is big, the settlement is good, the decolorization rate is more than 90%, the COD removal rate is very high, the sludge quantity is small.
