Project Overview: (1) Phase I Reconstruction Project of Petrochemical Industrial Park Sewage Treatment Plant: The design scale of the existing plant area of the petrochemical industrial park sewage treatment plant is 5 × 10000m/d, and the reconstruction scale is 5 × 10000m3/d. According to the current water quality indicators, the effluent quality of the wastewater treatment plant in the petrochemical industry park can basically meet the water quality requirements, except for total phosphorus, COD, BOD, SS, ammonia nitrogen, and total nitrogen. Therefore, this renovation mainly focuses on total phosphorus, and the effluent quality indicators after the renovation reach the first level A standard. (2) Pump station upgrading and renovation project: The pump station upgrading and renovation project includes the Baijiantan sewage lifting pump station, Sanping Town sewage lifting pump station, and Jinlong pump station.

The project is undertaken by the general contractor Shaanxi Wangtong Construction Engineering Co., Ltd. (formerly Shaanxi Wangtong Construction Engineering Co., Ltd.), and the waste gas treatment section is subcontracted. Shaanxi Wangtong Construction Engineering Co., Ltd. (formerly Shaanxi Wangtong Construction Engineering Co., Ltd.) was established in 2017 and is located in Baoji City, Shaanxi Province, the hometown of Emperor Yan. It is a construction enterprise with great development prospects and vitality. Wangtong Construction Engineering is mainly engaged in engineering construction, with a second level general contracting for construction projects and a second level general contracting for municipal public works; Third level general contracting for highways, water conservancy, and electromechanical engineering; The company has an Administration Department, Chief Engineer's Office, Quality and Safety Management Department, Engineering Technology Department, Business Department, and Finance Department. Wangtong has a registered capital of 41 million yuan. We have various types of large and medium-sized construction machinery equipment and testing instruments. There are currently more than 234 employees and various management personnel, including more than 140 professional and technical personnel, 10 senior engineers, 24 intermediate technical title personnel, 6 first level construction engineers, and 24 second level construction engineers.

Eclear Environmental has specially developed a portable "nano photocatalysis ion cabinet machine" for small sewage pump stations and garbage houses. It uses an intelligent deodorization disinfection and sterilization system with enhanced oxidation disinfection and sterilization technology to quickly deodorize and remove odors, deeply sterilize and sterilize odorous and odor gases from the source, and continuously purify the air. The intelligent deodorization disinfection and sterilization system has the advantages of energy conservation, environmental protection, harmless to human body, no secondary pollution, etc. It releases a large number of disinfection and sterilization factors, captures bacteria, viruses, odor molecules in the environment, and decomposes them to reduce sedimentation, purify the air, and improve the environment.

The project is located at the junction of Huilong Town and Huiping Town in Qidong City. It belongs to the artificial ecological wetland purification project for the tail water of the Second Urban Sewage Treatment Plant in Qidong City. The total investment is 63.5263 million yuan (including environmental protection investment of 11.9185 million yuan), and the engineering land area is about 20 hectares (the core purification treatment area of the wetland is about 80000 square meters). The recent design inflow scale is 40000 cubic meters/day, and the long-term inflow scale is 80000 cubic meters/day. The main project includes tail water discharge pipes, ecological ponds, surface flow wetlands, subsurface wetlands, submerged plant ponds, etc., with supporting construction of public and auxiliary projects and ecological environmental protection projects. The environmental impact assessment documents for the Qidong City Second Sewage Treatment Plant project have been approved (Qixing Shenhuan [2023] No. 45) and construction has been implemented. The project has been approved for approval (project code: 2204-320681-89-01-753687).
