猎德污水处理厂
广州市猎德污水处理厂是广州市第2座大型城市污水处理厂，位于天河区猎德村以东、华南大桥珠江北岸，占地面积39万平方米，主要负责收集处理珠江前航道以北的大部分市中心区，包括西濠涌、沿江自排系统、东濠涌、二沙岛及天河区的部分污水，服务面积228平方公里，服务人口约296万人。该厂分三期建设，一期工程于1991年立项，1999年正式投产，设计日污水处理能力22万吨，采用AB两段吸附降解生物处理工艺；二期工程于2002年4月动工，2003年10月通水运行，设计日污水处理能力22万吨，采用组合交替活性污泥法处理工艺；三期工程于2004年动工，2006年11月通水运行，设计日污水处理能力20万吨，采用改良A2/O工艺（缺氧/厌氧/好氧）。三期工程全部建成后，日处理能力达64万吨。 该厂运行以来，着力建立科学的管理体系，构建起“ISO9001质量管理体系、ISO14001环境管理体系、OHSAS18001职业健康安全管理体系”三位一体科学管理体系，确保各项出水指标均优于国家一级B标准。同时，注重科技创新，自主研发设备管理软件和泵站远程通讯系统，并进行一系列技术改造，其中加盖除臭技术应用走在全国污水处理厂前列。
■Liede Wastewater Treatment Plant
Situated east of Liede village of Tianhe District and at the north bank of the Pearl River close to the South China Bridge, Guangzhou Liede Plant is the city's second large-scale wastewater treatment plant. Occupying an area of 390,000 square meters, it collects and treats the wastewater discharged mainly from the central city area of the North Waterway of the Pearl River, including the wastewater from Xihao Stream, the self-discharge system of the Pearl River, Donghao Stream, Ersha Island and some parts of Tianhe District, serving an area of 228 square kilometers and a population of 2.96 million.
The plant is constructed in three phases. The first stage, approved to start in 1991, was put into operation in 1999 with a designed treatment capacity of 220,000 tons of wastewater per day and supported by a biological treatment technology of two-section (AB) adsorption and degradation. The second phase was started in April 2002 and put into operation in October 2003 with a daily treatment capability of 220,000 tons. The technology adopted is composite alternating activated sludge processing. The third stage, started in 2004, was put into operation in November 2006 with daily handling capability of 200,000 tons, and backed up by the modified A2/O (anoxia/anaerobic/benign oxygen) technology. Upon completion of the three phases, the total treatment capability will reach 640,000 tons a day.
Since operation, a scientific management system has been constructed by incorporating the three management systems of ISO9001 in quality, ISO14001 in environment and OHSAS18001 in occupational health safety to ensure that the water standards exceed the B criteria of the national A-level. The factory also leads the country in terms of technical innovations and renovations, R&D of the equipment management software and the long-distance communication system between pumping stations, particularly the sealed deodorization technology.
