Jinghong Environment

Wuhan Jinghong Ecological Environment Co., Ltd. (hereinafter referred to as "Jinghong Environment") is located in the *** high-tech development zone—Wuhan East Lake New Technology Development Zone, with a registered capital of 138 million RMB. In August 2013, the company was officially listed on the National Equities Exchange and Quotations, with stock code 430283. As a provider of integrated solutions for environmental protection and comprehensive treatment, the company specializes in sewage treatment, air pollution control, environmental ecological restoration, environmental protection operations, and other businesses. It is a comprehensive high-tech enterprise integrating environmental engineering consulting, environmental treatment system design, environmental protection engineering general contracting, environmental protection equipment design and manufacturing and installation, and environmental protection facility operation and management. Its main business involves municipal, metallurgical, building materials, chemical, machinery, light industry and other fields, and it possesses a full set of qualifications for engineering design, engineering contracting, manufacturing and installation, and environmental protection facility operation and management. In December 2015, the company received the "China Industry-University-Research Cooperation Promotion Association Innovation Award" at the "9th China Industry-University-Research Innovation Conference." In December 2015, the Wuhan Municipal Government also received the "C40 Cities Climate Leadership Award" "*** Solid Waste Treatment Award" at the United Nations Climate Conference for the Jinkou landfill aerobic remediation project led by the company. The company has also successively received titles such as "Hubei Province Outstanding Private Enterprise," "Contract-honoring and Credit-reliable Enterprise," and "AAA Credit Enterprise," and is a vital force in the environmental protection industry. The company's main core technologies include: 1. Landfill aerobic remediation technology; 2. Sand-added high-efficiency sedimentation technology; 3. "SANI technology." The company attaches importance to talent cultivation and introduction, and to corporate culture and team building. "Protecting clear waters and blue skies, defending beautiful homes" is the company's unremitting pursuit. The company is committed to bringing more and better new environmental protection technologies, products, and services to customers.
1. Landfill aerobic remediation technology. The aerobic biological remediation technology for landfills injects air into the landfill waste body in a controllable manner, rapidly transforming the anaerobic environment of the waste body into an aerobic environment, making the degradation rate of waste 20-30 times faster than under anaerobic conditions, greatly shortening the stabilization time of the landfill. Aerobic remediation technology is also called "aerobic aeration method." The specific operation method is to pressurize fresh air and inject it into the deep part of the waste body through pipelines, while extracting gases such as carbon dioxide and methane, and monitoring reaction temperature, humidity, extracted gas composition, and gas quality, creating an *** state conducive to aerobic reactions, activating microorganisms in the waste body, and accelerating degradation. Compared with traditional landfill technology, aerobic biological remediation technology requires a relatively large one-time investment, but the treatment cycle is short, and the main process equipment can be reused.
2. Sand-added high-efficiency sedimentation technology. This technology has a very short startup time, less than 10 minutes, and can flexibly respond quickly to changes in raw water quality; it ensures high-quality effluent water quality, and the produced sludge is easy to concentrate and dewater, with a turbidity removal rate > 90%. Compared with traditional sedimentation tanks, it occupies a very small area, can reduce civil engineering works, and is very suitable for water plants with limited land and for upgrades and renovations of existing water plants. This technology requires very little equipment maintenance, is easy to operate, and can achieve full automatic control and remote control.
3. "SANI technology." This technology is a new energy-saving and low-carbon sewage treatment technology developed through cooperation between Wuhan Jinghong Ecological Environment Co., Ltd. and the Hong Kong University of Science and Technology, by Professor Chen Guanghao's research group at HKUST. The *** characteristic of SANI technology is that it can effectively reduce the production of excess sludge, solving from the source the problems currently faced by sewage treatment plants, such as large sludge volume, difficult treatment, and high costs. The full name of the SANI process: sulfate reduction, autotrophic denitrification, and nitrification integrated process. At present, it is mainly applied to the treatment of seawater toilet-flushing sewage in coastal areas.
In recent years, while engaging in the traditional environmental protection dust removal business, the company has vigorously expanded aerobic remediation projects for landfills. It has successively undertaken and constructed the Wuhan Jinkou landfill remediation project and the Liucun landfill remediation project in Anxin County, Baoding City, and by the end of 2017 had successively won bids for the Wuhan Daishan simple domestic waste landfill ecological remediation project (contract amount 34.38 million RMB) and the Wuhan Beiyangqiao simple domestic waste landfill ecological remediation project (contract amount 78.49 million RMB). Next, it will continue to expand landfill remediation projects nationwide.
