Jiangsu Qianyan Environmental Technology Co., Ltd. is registered in Jiangning District, Nanjing City, Jiangsu Province. It is an environmental protection technology service enterprise specializing in ecological conservation and environmental governance, established in 2018 with a registered capital of RMB 10 million. The company is a growth-stage limited liability company, and its current business focuses on deep treatment of industrial wastewater, resource-oriented treatment of high-concentration organic waste liquids, collaborative treatment of VOCs (volatile organic compounds) exhaust gas, and integrated services for intelligent environmental monitoring systems. Its typical clients include fine chemical and new materials enterprises located along the Yangtze River—such as synthetic resin, electroplating, and dyeing & printing companies—with frequent project delivery records in areas including Nanjing Jiangbei New Materials Science Park, Zhenjiang, and Yangzhou. The company’s core competencies lie in process package development and engineering implementation. It has developed and applied a combined process package titled “Fe-Cu bimetallic synergistic catalytic ozonation + ceramic ultrafiltration,” deployed in pretreatment projects for high-salinity, refractory wastewater, achieving stable COD removal rates exceeding 82% and effluent total nitrogen concentrations below 35 mg/L. Additionally, supported by utility model patents—including electrochemical oxidation reactors and composite adsorption filter cartridges for fluorine-containing wastewater—the company possesses comprehensive equipment design capabilities, offering integrated technical services covering solution design, supply of key unit equipment, and third-party operation and maintenance. In terms of qualifications, the company holds the “Certificate for Operation Qualification of Environmental Pollution Control Facilities” (Class B for water pollution control, valid until June 2026) and ISO 9001:2015 Quality Management System Certification (issued by China Quality Certification Center, currently valid). Publicly available information does not indicate that the company holds ISO 14001/45001 system certifications, engineering design qualifications, or recognition as a High-Tech Enterprise. Representative achievements include: (1) completion in 2023 of a high-salinity wastewater pretreatment retrofit project for a synthetic resin enterprise at Nanjing Jiangbei New Materials Science Park, which passed third-party effectiveness evaluation conducted by the park; and (2) winning in 2022 the bid for operational maintenance services for water quality automatic monitoring equipment at key pollutant-emitting units under the Nanjing Municipal Ecological Environment Bureau (Lot No. 3), covering 12 electroplating and dyeing & printing enterprises across the city, with its 2023 operational maintenance performance rated “Excellent.” Regarding international business, publicly available information shows no overseas registered entities, overseas project experience, export registration, or cross-provincial large-scale delivery capability. Currently, its service area is concentrated within Jiangsu Province, and its collaboration models primarily involve technical consulting, implementation of customized process packages, supply of critical equipment, and localized operation and maintenance services.
