名称解释-氧化塘法(国外英文资料) Oxidation pond method - text Using the microorganism and algae in the pond to carry out the aerobic biological treatment of sewage and organic waste water. Has a long history of wastewater treatment with oxidation pond, North America and Australia regions such as vast land, the climate is suitable, the oxidation pond method is widely applied in medium and small town wastewater and some industrial wastewater treatment, such as pulp and paper wastewater, food processing wastewater. In recent years, with the rapid development of land treatment system, as an important part of its oxidation pond for greater development, a sewage aeration lake and so on the new type of oxidation pond. There are a number of cities in China with the oxidation pond method and treatment of waste water, wastewater treatment can not only effectively, and can be converted into use of organic matter in the biological wastewater oxidation process of algae protein fish, ducks, etc., to obtain good economic benefits. The process of purification of wastewater by oxidation pond is similar to the purification process of biodegradable water in the water body, so it is also known as the biological pond or biological oxidation pond method. In oxidation pond method of oxidation purification process with anaerobic reduction process, and in the deep part of the oxidation pond, high concentration of organic matter in waste water and oxygen supply is insufficient, the anaerobic reduction becomes the main process. In this case, the waste water will be decomposed by anaerobic biodegradation, and then by biodegradation of oxygen, which will be converted into water with stable water quality. Thus, the method of concatenation of the anaerobic and oxygen-needed oxygen is known as the stabilization pond method, but is still known as the oxidation pond method. How does it work? In the oxidation pond, the organic matter in wastewater is mainly removed by the symbiotic effect of bacillus. Heterotrophi
