In recent years, China's SUNNYJOINT Rubber additive industry has been rapidly developed, but it has also been plagued by the worldwide problems of wastewater treatment. A lot of wastewater will be produced during the production of rubber additives. This type of wastewater is generally composed of benzene, naphthalene, heterocyclic compounds and a small number of small molecules containing nitrogen or sulfur. It has the characteristics of high salt and organic pollutants and difficult to biochemical treatment. Because of the lack of useful wastewater treatment processes and skills, coupled with the large demand for wastewater treatment, many domestic rubber additives companies smuggle or dilute their production wastewater, forming a large area of water pollution, which seriously threatens people's production and days. The lack of useful processing of rubber auxiliary wastewater has become a bottleneck for the development of rubber additives industry in China.
The company actively responded to the country's proposal to build an environment-friendly society, and actively developed new technologies for energy conservation, emission reduction, pollution reduction and efficiency enhancement, and conducted many experiments and discussions on wastewater treatment problems that plagued occupational development. In view of the complex composition of wastewater from rubber auxiliaries, high concentration of toxic organic pollutants, high salt content and difficult biochemical degradation, we have summarized the various skills at home and abroad through various investigations, investigations, summarizations and verifications. Investigate and discuss, formed a set of effective new skill plans, namely multi-effect transpiration and biochemical combination process, and successfully used in rubber additive wastewater treatment, and achieved significant benefits.
The process has undergone a number of innovations in the development and implementation process and has achieved outstanding results. If the composite bio-oxidation method is used, the high, medium and low loads in the biochemical process are significantly separated, and the advanced biochemical treatment effect, shortening the time of the touch oxidation, and the biological treatment process of the obligate bacteria have strong anti-impact load capacity. The sludge has good sedimentation performance, easy to be solid and liquid, and the intention of operation; the heater is made of titanium alloy with strong corrosion resistance and good heat transfer performance, and the HPP plastic raw material with high corrosion resistance and low price is selected for the steam and water separation chamber. The equipment is corrosion-resistant, prolongs the service life of the equipment, and minimizes the failure rate of the equipment. The salt purification technology is used to make the organic substances in the inorganic salts useful. After the inspection, the treated sodium chloride can satisfy the skill requirements of the chlor-alkali occupation. To complete the recovery and use of valuable components in wastewater; classify the production wastewater and daily sewage, which is beneficial to the reuse of industrial wastewater after treatment, reduce the discharge of sewage and reduce the treatment cost; the microorganisms in the composite biochemical section of the process pass Breeding and domestication, screening out suitable obligate bacteria, and then greatly improving the processing power; The transpiration water reuse skill enables the transpiration water to be reused as process water in the workshop, and the waste water discharge and water resource reuse are completed. The solvent extraction method is adopted, the solvent and the organic matter are separated by distillation, the solvent can be reused, and the residue salt is purified. After that, all of its objectives have met the requirements of GB/T5462-2003 industrial salt, which can be used for industrial production.
Its goal of passing the treated wastewater is in full compliance with national emission standards. Together, the wastewater will be recycled through treatment, saving 90,000 cubic meters of water per year, reducing the pressure of water resources that are increasingly lacking; the recovery of valuable materials not only reduces environmental pollution damage but also achieves certain economic benefits. The recovery of many inorganic salts has completely affected the environmental impact of inorganic salts. It has effectively curbed the salinization of environmental soils, reduced the cost of treatment, and has outstanding social benefits.
