Guangzhou Hound Sewage Treatment Plant is the 2nd large-scale urban sewage treatment plant in Guangzhou, located in Tianhe District, east of Hound Village, South China Bridge on the north bank of the Pearl River, covers an area of 390,000 square meters, is mainly responsible for the collection and treatment of most of the city center area north of the Pearl River's former navigation channel, including Xihaochong, along the river self-discharge system, Donghaochong, Ersha Island, and some of the sewage of Tianhe District, with a service area of 228 square kilometers. The service population is about 2.96 million. The plant is divided into three phases of construction, the first phase of the project in 1991, officially put into operation in 1999, the design capacity of 220,000 tons of sewage treatment, the use of AB two-stage adsorption and degradation of biological treatment process, the total project investment of more than 1.2 billion yuan (including part of the second phase of the project); the second phase of the project started in April 2002, the water was turned on in October 2003, the design capacity of 220,000 tons of sewage treatment The second phase of the project was started in April 2002 and put into operation in October 2003, with a design capacity of 220,000 tons of sewage treatment per day, adopting the combined alternating activated sludge process; the third phase of the project was started in 2004 and put into operation in November 2006, with a design capacity of 200,000 tons of sewage treatment per day, and adopting the improved A2/O process (anoxic/anaerobic/electro-oxic).
Hunde sewage treatment plant, the completion of the first and second phase of the project put into operation marks the Guangzhou City sewage treatment undertakings on a new stage, it will be in the Guangzhou Municipal Government, Municipal Bureau of Landscape Architecture and municipal wastewater management limited liability company under the leadership of the "purification of the water quality, for the benefit of the people" as the mission, the early purification of the Pearl River, to recreate the beauty of the water blue fish leaping. Water blue fish leaping beauty, for the sustainable development of Guangzhou City, the public's life to create a better ecological environment to make greater contributions!
After the completion of all three phases of the project, the daily treatment capacity of 640,000 tons. Hunt sewage treatment plant outside the plant *** with Donghaochong, Xihaochong, Tianhe South Road, Linhe East Road, four sewage lifting pumping station, of which Donghaochong pumping station also undertakes the task of flood control and drainage in the central city. The main structures in the plant include: lifting pumping station, sand sedimentation tank, biological reaction tank, secondary sedimentation tank, thickening tank, dewatering machine room, contact tank and so on. After the sewage is transported to the plant from the pumping station outside the plant, it passes through the coarse and fine grating in the lifting pump room of the plant to remove the larger suspended and floating matters in the sewage; then it is lifted by the centrifugal submersible pump and enters into the elevated drainage box of the plant to flow into the sand sedimentation tank; the sewage treated by sand sedimentation enters into the first and second phase of the bioreactor for treatment, and then passes through the second sedimentation and disinfection to meet the standard of discharge.
The total installed capacity of the system equipment in the plant is 3100KW, and the central control room of the plant is designed with "DOS" centralized measurement and control system, which realizes the operation and management of the production and process through the 12 on-site measurement and control workstations set up in the network of industrial computer terminals. The sludge treatment process adopts direct dewatering of raw sludge. Since the plant has been in operation, it has endeavored to establish a scientific management system and built up a trinity scientific management system of "ISO9001 Quality Management System, ISO14001 Environmental Management System and OHSAS18001 Occupational Health and Safety Management System" to ensure that all the effluent indexes are better than the national level B standard. At the same time, focusing on scientific and technological innovation, independent research and development of equipment management software and pumping station remote communication system, and a series of technological transformation, which cover deodorization technology application in the forefront of the national sewage treatment plant.
Hunde Sewage Treatment Plant Phase IV project in September 2009, June 2010 water operation. Design capacity of 560,000 tons of sewage per day, the use of improved A2 / o process (pre-anoxic / anaerobic / anoxic / aerobic). In addition, the fourth phase of the project has a high-efficiency sedimentation tank, which can be used to treat combined rainwater during the rainy season, with a design capacity of 560,000 tons of sewage treatment per day. Together with the original one, two, three phases of the treatment capacity, Hunde sewage treatment plant will reach 1.2 million tons of daily treatment capacity, will become the sewage treatment plant in Guangzhou City, "boss". After upgrading and expansion of the Hunde sewage treatment plant "appetite" will be greatly increased, its overall sewage area will cover most of the city center north of the Pearl River former channel, including Xihaochong, along the river from the system, Donghaochong, Ersha Island, and a part of the Tianhe District, the service area of 143.3 square kilometers, serving a population of about 2.26 million people.
According to the person in charge of the Hunter IV project, with other sewage treatment plant is different, Hunter IV according to the quality of incoming water as well as emission standards, in the treatment process using internationally advanced equipment rotary disc filter as a depth treatment process, that is, sewage through the city sewage network collection to the sewage treatment plant before the elevation of the pumping plant, through the elevation of pumping room to enhance access to pumping station outlet channel, fine grating, aeration Sand sedimentation tank, biochemical tank, the second sedimentation tank, and finally through the carousel filter, ultraviolet disinfection pool water, greatly improving the water quality standard of the water leaving the plant. In addition, another highlight of the project is the use of high-efficiency precipitation as the first rain treatment process. When the rainy season comes, a large number of relatively small impurities containing rain and sewage combined water can be treated by the aeration sand sedimentation tank into the high-efficiency sedimentation tank separate treatment. The technology not only improves the treatment efficiency, but also saves treatment costs; and in the dry season, high-efficiency sedimentation tank can be used for Hunter Phase II project part of the biochemical effluent depth treatment, two birds with one stone. According to reports, the first rain precipitation tank will reach 660,000 tons of daily capacity, ranking among the forefront of similar projects in the country.
