Description

Multi-stage treatment biological pond applied to activated sludge process A/O (anaerobic/oxic) process

Technical Field

The invention belongs to the technical field of sewage treatment, and particularly relates to a multistage treatment biological tank applied to an activated sludge process A/O (anaerobic/oxic) process.

Background

The urban domestic sewage is a product in urban development, and with the acceleration of the process of urbanization and industrialization, the production amount of the urban domestic sewage is continuously increased, the pollution is increasingly serious, and the sustainable development of urban social economy is seriously restricted. The treatment of water pollution and the protection of water resources are not only global problems but also urgent matters generally faced in cities and countryside of China. The urban sewage is various kinds of sewage collected by urban sewer systems, and is mixed sewage. The urban sewage can be discharged into the water body only after being treated to reach the relevant discharge standard, so that the water body pollution is avoided. At present, the sewage discharge amount of small and medium-sized cities accounts for more than half of the total sewage discharge amount of China, and with the rapid development of urban construction in the future 50 years, the discharge amount of domestic sewage is increased by several times or even more than ten times, so that the deterioration of the water environment is increased. Therefore, when the treated water of the municipal sewage treatment plant is reused, corresponding water quality standards and corresponding advanced wastewater treatment processes are required to be implemented according to the use purposes. The country has already listed urban water supply and drainage as the industry of the key support in the field of basic construction, the reclamation of sewage, the recycling of sewage, have already improved the utilization factor of water and protected the water environment effectively, help to realize the health of the urban water system, benign cycle, from the long run, this will be the optimization way to solve the water resource shortage and water environment of our country worsen the problem effectively.

The domestic sewage treatment process is divided into a pretreatment process, a primary treatment process, a secondary treatment process, an advanced treatment process, a sludge treatment process and final sludge treatment according to the flow and treatment procedures. The determination of the process is comprehensively determined according to various factors of urban water environment quality requirements, incoming water quality conditions, available technical development states, urban economic conditions, urban management operation requirements and the like. At present, the domestic application is more in types of A-O or A-A-O process, SBR process, oxidation ditch process and the like.

Wherein, the A-O method (anoxic-aerobic method) treats the domestic sewage. The A/O is the abbreviation of antioxidant/Oxic, and has the advantages that organic pollutants are degraded, certain nitrogen and phosphorus removal functions are realized, anaerobic hydrolysis technology is used as pretreatment of activated sludge, and therefore the A/O method is an improved activated sludge method.

When the A/O method is used for treating sewage, the steps of filtering and precipitating are needed, and precipitated sludge impurities are located at the bottom of a pool in the precipitating process.
