(Summary description)Runshi Chemical (Changshu) Co., Ltd. is an environmentally friendly enterprise that uses IT waste liquid and miscellaneous copper to produce copper salts and related products. As the composition of the main raw material IT waste liquid used by Ruan's Chemical Industry has undergone great changes: the copper content of acid etching solution, alkaline etching solution, and copper sulfate waste liquid has changed. Ruan's Chemical Industry (Changshu) Co., Ltd. intends to invest 300 Ten thousand dollars for technical transformation of the original project. The technical renovation project cancels the production of explosive and dangerous sodium nitrate, and cancels the ammonia production of basic copper carbonate facilities. In addition, some new equipment was added to the original production plant to form a new 96% wet copper oxide 6000t/a, 98% copper hydroxide 16

Information

Runshi Chemical (Changshu) Co., Ltd. is an environmentally friendly enterprise that uses IT waste liquid and miscellaneous copper to produce copper salts and related products. As the composition of IT waste liquid, the main raw material used by Ruan's Chemical Industry, has undergone great changes: the copper content of acid etching solution, alkaline etching solution, and copper sulfate waste liquid has changed, Ruan's Chemical Industry (Changshu) Co., Ltd. plans to invest 300 Ten thousand dollars for technical transformation of the original project. The technical renovation project cancels the production of explosive and dangerous sodium nitrate, and cancels the ammonia production of basic copper carbonate facilities. In addition, some new equipment was added to the original production plant to form a new production capacity of 6000t/a of 96% wet copper oxide, 1628t/a of 98% copper hydroxide, 185.8t/a of 96% calcium nitrate, and 6000t/a of stripping liquid. Due to changes in the composition of the main raw materials, the production process and equipment of other products in the original EIA cannot meet the production requirements. Therefore, this technical reform will modify the production process without increasing the production capacity of other original products.

On January 20, 2016, the Suzhou Economic and Information Technology Commission’s corporate investment project filing notice (3205001600308) for this project was issued on January 20, 2016. In June 2016, Jiangsu Zhongrui Consulting Co., Ltd. completed the preparation of the environmental impact assessment report. On May 10, 2016, the Changshu City Environmental Protection Bureau Changhuanjian [2016] No. 112 issued a preliminary review, and the Suzhou City Environmental Protection Bureau Suhuanjian [2016] No. 95 approved the preliminary review on August 1, 2016. The project Construction started in August 2016, and the technical transformation of the project was completed in March 2017. On March 23, 2017, the Suzhou Environmental Protection Bureau Suhuan Trial Report [2017] No. 20 issued a trial production notice, and the trial production was carried out in April 2017, 2017 The acceptance monitoring was completed in September 2015, and the acceptance review was conducted on March 5, 2018.

Our company implements "rain and sewage diversion, clean sewage diversion, separate quality treatment, and one water for multiple purposes". After the company-wide process wastewater is treated by evaporation and reverse osmosis, the evaporated condensed water and reverse osmosis fresh water are reused, and the concentrated water and cooling cycle are recycled. Waste water, primary rainwater and domestic sewage in the plant area have been treated by flocculation and sedimentation and then taken over by Binjiang New District Sewage Treatment Co., Ltd. The newly added natural gas rotary kiln waste gas is discharged from the 1# exhaust cylinder. The acid waste gas hydrogen chloride, sulfuric acid mist, and nitrogen oxides are collected and processed by 4 sets of alkaline scrubbers and then passed through the 15-meter-high 2#, 3#, and 4# respectively. , The 7# exhaust cylinder is discharged. The dust is treated by the bag dust removal device (5 sets) and then combined and discharged by the 15-meter-high 6# exhaust cylinder. The 5# exhaust cylinder is discharged. After the ammonia gas is collected, it is treated by the secondary water washing tower and then discharged through the 15-meter-high 8# exhaust cylinder. All exhaust gases are discharged after being treated to reach the standard. In terms of noise, measures such as sound insulation, noise reduction, and vibration reduction have been adopted. The hazardous solid waste is entrusted to Jiangsu Kangbo Industrial Solid Waste Disposal Co., Ltd. for disposal, and the domestic waste is handled by the local environmental sanitation department.
