Abstract

The invention discloses an integrated sewage treatment bench-scale device and a process method. The device comprises an integrated container body, a first anoxic area, an anaerobic area, a first aerobic area, a second anoxic area, a second aerobic area, a membrane area, a water storage tank, a sludge storage tank, a sludge backflow pipe, a mixed liquid backflow pipe, membrane components, hydraulicstirrers, valves, air flow meters, peristaltic pumps, self-priming pumps, air compressors, scavenging pumps, pressure meters, relays, aeration heads, aeration pipes, partition plates, a water inlet,a sludge outlet, a water outlet and supporting frames. By denitrification of returned sludge and mixed liquid in a first anoxic tank, an anaerobic state in the anaerobic area is guaranteed, and a phosphorous removal effect is enhanced; due to backflow of sludge to the anoxic areas, the denitrification rate is increased; by input of a carbon source in the first and second anoxic areas, the denitrification effect can be effectively guaranteed; by additional arrangement of the second aerobic area behind the second anoxic area, influences on the membrane components can be effectively reduced, andeffluent quality of the membrane area is guaranteed.

Description

technical field

[0001] The invention relates to an integrated sewage treatment small test device and a process method, belonging to the field of water treatment engineering design. Background technique

[0002] Environmental problems are common problems faced by all countries in the world today, and the current global environmental crisis poses a serious threat to human survival and development. Water is the lifeline of human survival and development, and the current water pollution problem has seriously affected people's life and property safety and hindered the further development of the national economy. my country's surface water pollution is very serious, and the eutrophication of lakes and reservoirs is prominent. The main pollution indicators are inorganic nitrogen and phosphate. Specifically, the inorganic salts rich in nitrogen and phosphorus in seawater and lakes mainly come from the production and use of a large amount of nitrogen and phosphorus fertilizers in ag...
