The water resource is a natural resource essential for human production and life, and is also an environmental resource on which organisms live and an economic resource supporting healthy development of national economy. Since the industrial revolution, the rise of large industry, the mechanization of agriculture, the use of pesticide and fertilizer in large quantities, the rapid development of urbanization and the like, a large amount of wastewater is discharged into rivers, lakes and seas, and the water environment is deteriorated. The shortage of water resource and the deterioration of water quality cause the serious deterioration of the ecological system of the river, which results in the phenomena of water and soil loss, serious erosion of the bank, reduction of biodiversity and the like. The urban landscape water comprises artificial lakes, small natural lakes, artificial landscape lakes configured for real estate construction and the like, is in a special environment which is greatly different from the natural environment, and is mostly a slow-flow water body with static or poor liquidity, so that the self-purification capacity of the water body is insufficient, the water body is easy to become a receptor for domestic sewage, rainwater, garbage and the like, and water body pollution and eutrophication are caused to different degrees.
Municipal sewage mainly consists of four parts, including: domestic sewage generated in the life process of urban residents, production wastewater generated in the production process of enterprises, urban precipitation and part of polluted surface water. The biochemical performance of the municipal sewage is better, and the general BOD5The COD can reach 0.5-0.6, and the obvious characteristics are that the change of water quality and water quantity has seasonal periodicity and day and night periodicity; domestic sewage pretreatment in most areas of China takes a small area as a unit, and pretreated water is directly discharged into a natural water body through a sewer system; the domestic, office and commercial areas are mixed together, and domestic sewage and urban sewage discharge share a set of sewer system. Therefore, the method has the characteristics of large amount, multiple sources and wide range of domestic sewage in cities of China.
The municipal sewage treatment technology can be classified into physical, chemical and biological methods according to the principles of municipal sewage treatment. Biological treatment is the most economical, effective and widely applied method for solving the problem of urban sewage, and is an important guarantee for sustainable development of water resources. The principle of biological sewage treatment is to provide conditions favorable for the enrichment and growth of microorganisms in a bioreactor, mainly including nutrient conditions and dissolved oxygen conditions, so as to strengthen and accelerate the effective degradation of the microorganisms on various organic pollutants and achieve the aim of purifying sewage.
