II. The Construction and Operation of Pollution Control Facilities
1. SKSHU Paint Co., Ltd. (Putian Factory)
Acting in strict accordance with the "Three Simultaneities" requirements for construction projects, the company has enhanced its environmental protection facilities to ensure the stable and qualified discharge of various environmental factors. The workshops are equipped with dust removal and degassing facilities, sewage treatment stations are established, solid waste storage yards are up to the standards, and measures such as wind and rain protection, leakage and loss prevention are taken. The main environmental protection facilities are:
(1) VOC treatment and dust removal devices: In wood paint A and B workshops, and adhesive and resin workshops, pulse sedimentation dust removal and zeolite runner RTO combustion devices are adopted to treat organic waste gas; the solvent for which is adsorbed in the gap of zeolite runners through the porosity of zeolite runners and the tension of the gap surfaces so that the discharged waste gas is purified. When zeolite wheels are saturated with the solvent, the latter is desorbed and regenerated by hot air, and the detached organic matter is oxidized at a high temperature to convert the organic waste gas into carbon dioxide and water. In latex paint and texture paint workshops, sedimentation dust removal devices are used to remove dust in waste gas and reduce the emission of harmful substances such as particles in the gas.
(2) Sewage treatment stations: waste water from reactor cleaning, workshop floor washing and laboratory as well as sanitary sewage from workshop employees is treated by the existing sewage treatment stations, discharged into the municipal sewage pipe network after measuring up to the standard, and merged into Minzhong Waste Water Treatment Plant for further treatment. And at the sewage treatment stations is adopted a combination of physical and biochemical treatment as well as processes of grid filtering, sedimentation and biological contact oxidation of stable treatment effect and high pollutant removal rates. Resin organic waste water treatment is done by a set of sewage treatment equipment (catalytic micro-electrolysis devices, ultra-high load integrated bio-reactors, circular biological reaction devices, up-flow anaerobic filters, photo-Fenton oxidation devices, hydrolysis devices, flocculation precipitator, etc.). Upon reaching the standard, the waste water is discharged into the municipal sewage pipe network and merged into Minzhong Waste Water Treatment Plant for further treatment.
These environmental protection measures have enabled the company to meet the emission standards approved by EIA in terms of treated sewage and waste gas, and environmental protection requirements for factory boundary noise. And all of the environmental protection facilities could run stably, with the synchronous operation of the facilities up to the requirements.
