In strict accordance with the "Three Concurrents" requirements for construction projects, SKSHU Paint Co. Ltd. has improved its various environmental protection facilities to ensure stable and compliant emission. All its workshops are equipped with dedusting and degassing facilities. In the meantime, the company has also built a sewage treatment station, standardized solid waste storage site construction, and taken protective measures against wind, rain, leakage and loss. Its main environmental protection facilities include:


Waste gases generated in the company’s Wood Paint Workshops A and B, Adhesive Workshop and Resin Workshop are treated by pulse deposition dust removal + zeolite molecular sieve adsorption concentration runner + RTO regenerative combustion device, which can meet the requirements of Table 2 of Integrated Emission Standard of Air Pollutants (GB 16297-1996) and Table 4 of Emission Standard of Pollutants for Synthetic Resin Industry (gb31572-2015). Waste gases generated in emulsion, texture, granite and auxiliary material workshops are emitted according to the standard after collection by pulse-type precipitators. The precipitators mainly remove dust from the waste gases, reduce the emission of harmful substances such as particulate matter and meet the Grade II Standard in Table 2 of Integrated Emission Standard of Air Pollutants (GB 16297-1996).


Domestic sewage in the plant area is directly discharged into the municipal pipe network after passing through a septic tank. It meets the Grade II Discharge Standard in Table 4 of Integrated Wastewater Discharge Standard (GB8978-1996) and the Grade B Standard of Wastewater Quality Standard for Discharge into Urban Sewers (GB/T31962-2015). Production wastewater is discharged into the comprehensive sewage treatment station in the plant area after being treated by the pretreatment station. The sewage stations adopt a combination of physicochemical and biochemical methods to ensure stable treatment effect and high pollutant removal rate. Production wastewater discharge meets the Grade III Standard in Table 4 of Integrated Wastewater Discharge Standard (GB8978-1996). After entering the municipal sewage pipe network, production wastewater is brought to the Minzhong Sewage Treatment Plant for further treatment. Currently, the company has a resin organic wastewater treatment system to treat high concentration organic wastewater in accordance with the Discharge Standard of Pollutants for Synthetic Resin Industry (GB31572-2015). However, following a product structure adjustment, the company has stopped resin production, and the system was put out of service in July 2019.   


To eliminate the impact of the noise inside the plant on outside residents, various measures have been taken in the workshops/factory buildings that are prone to cause big noise. For example, low-noise facilities and sound insulation doors are adopted for air compressor equipment to reduce noise. Thanks to these measures, noise at the boundary of the plant meets the Type III limit values of Emission Standard for Industrial Enterprises Noise at Boundary (GB 12348-2008).


Through the above-mentioned environmental protection measures, the treated sewage, waste gases and noise at SKSHU Paint Co., Ltd. have reached the emission standards specified in the EIA written reply document. All environmental protection facilities can operate stably, and the synchronous operation rate of the facilities meets the requirement.
