Guangzhou Datansha Sewage Treatment Plant
. The project was jointly designed by Guangzhou Municipal Engineering Design and Research Institute and china municipal engineering Huabei Design and Research Institute. Won the first prize of Guangzhou Environmental Protection Research and Design, the second prize of Guangdong Excellent Design and the third prize of the Ministry of Construction Excellent Design.
The sewage treatment process adopts biological phosphorus and nitrogen removal activated sludge process (A2/O for short), which was fully completed and put into operation at the end of October, 1989. After years of operation, it has been proved that the treated effluent completely meets the design requirements, which has obviously improved the water quality of the Pearl River reach near the plant and achieved remarkable social and environmental benefits.
the project contents include: (1) sewage pumping station, with 6 pumps (5 for use and 1 for standby) in the sewage pumping station of Aokou Pumping Station, with a total pumping capacity of 96,111m3/d, pumping the sewage from Sima Yong District to Datansha Sewage Treatment Plant for treatment; There are 4 pumps (3 in use and 1 for standby) in Liwan Pumping Station, with a total lifting capacity of 57,611 m3/d, which will pump the sewage from Liwan Chung to Datansha Sewage Treatment Plant for treatment. (2) The sewage treatment plant is located on the small island of Datansha in the western suburb of Guangzhou, covering an area of 211 mu. The sewage pumped by Liwan Pumping Station and Aokou Pumping Station is sent to the plant through pressure pipes.
sewage treatment in the factory area is divided into primary treatment and secondary treatment. The primary treatment consists of grit chamber and primary sedimentation chamber to remove larger particles of organic matter; The secondary treatment adopts biological phosphorus and nitrogen removal activated sludge method, which consists of biological reaction tank, secondary sedimentation tank and contact disinfection tank. Under anaerobic, anoxic and aerobic environment, the purpose of removing organic matter, nitrogen and phosphorus from sewage is achieved through the biochemical action of different kinds of microorganisms. Land for sludge digestion is reserved in the sludge treatment plant. However, considering the low content of organic matter in urban sewage in Guangzhou, the direct dehydration process of raw sludge is adopted, which consists of a sludge concentration tank, a sludge storage tank and a sludge dewatering machine room. After concentration and mechanical dehydration, the water content of sludge produced in the sewage treatment process can be reduced from about 98% to 75% ~ 81%, and then it will be transported to a sanitary landfill for sanitary landfill treatment with garbage.
project features: (1) according to the serious pollution of nitrogen and phosphorus in the water quality of the west channel of Guangzhou reach of the Pearl River (near the water source of Xicun Waterworks), the internationally advanced phosphorus and nitrogen removal process was selected for the first time in China. (2) Advanced equipment at home and abroad is selected in the design, such as microporous aerator, submersible pump, underwater agitator and sludge dehydrator, so as to reduce the energy consumption of treatment. (3) There is no leakage and crack after the construction of a large pool in a complex karst cave limestone area. (4) The automation degree is high, and the equipment is controlled according to the program, which is recorded and controlled by the computer in the central control room. The monitoring contents include pH, SS, MLSS, temperature, mud level, dissolved oxygen and redox potential. (5) The general layout of the treatment plant is reasonable and compact, with a high degree of greening and elegant environment, which is well received by domestic and foreign counterparts.

Xilang Sewage Treatment Plant (Phase I) covers an area of 113133m2, with a construction area of 17158m2 and a designed treatment capacity of 211,111m3/d. When the project is put into operation, it will effectively collect and treat all the sewage in Fangcun District and part of the sewage in Haizhu District, improve the water body in Guangzhou section of the Pearl River, protect the water quality of the water intake points of Xicun Waterworks, Shimen Waterworks, Xiaozhou Waterworks and Shixi Waterworks in Guangzhou, and optimize the investment environment, thus improving the quality of life of Guangzhou people and generating good environmental, social and economic benefits.
The plant area of Guangzhou Lijiao Sewage Treatment Plant
was built by stages. The first phase of the project was established in 1991 and officially put into operation in 1999, with a designed treatment capacity of 221,111 tons per day; The second phase of the project started in April 2112 and was put into trial operation in October 2113, with a design capacity of 221,111 tons per day. Liede Phase III started construction in 2114 and was put into trial operation on September 26th, 2116, with a design capacity of 211,111 tons per day. The first phase of our plant adopts AB two-stage adsorption and degradation biological treatment process, the second phase adopts combined alternating activated sludge process, and the third phase adopts improved A2/O process (anoxic/anaerobic/aerobic activated sludge process). There are four sewage lifting pumping stations outside the factory, namely Donghaoyong, Xihaoyong, Tianhe South Road and Linhe East Road, among which Donghaoyong Pumping Station also undertakes the task of flood control and drainage in the central city. The main structures in the plant include: lifting pump house, grit chamber, biological reaction tank, secondary sedimentation tank, concentration tank, dewatering machine room and contact tank. After the sewage is transported to the factory by the pumping station outside the factory, it passes through the thick and thin grid of the lifting pump house inside the factory to remove the larger suspended solids and floating objects in the sewage; Then it is lifted by centrifugal submersible pump into the elevated canal box of the factory and flows into the grit chamber; The sewage treated by grit removal enters the first and second biological reaction tanks for treatment, and then reaches the standard after secondary sedimentation and disinfection.
at present, the factory has established a scientific management system of "quality, environment, occupational health and safety", standardized production and safety, and ensured the completion of water treatment tasks and the stable discharge of effluent quality. Since Liede Wastewater Treatment Plant was put into operation, the water quality of Guangzhou section of the Pearl River has been obviously improved. As of February 5, 2116, statistics show that the total sewage treatment amount of Liede Plant has reached 65.12 million tons this year, and the annual production task of 64.477 million tons has been successfully completed 25 days ahead of schedule, and all the treated effluent has reached or exceeded the national first-class B standard.
