Description

UASB sewage treatment plant Technical Field The utility model relates to the technical field related to sewage treatment, in particular to a UASB sewage treatment device. Background Anaerobic treatment of wastewater is a water treatment technology which combines wastewater treatment with energy recovery and has low cost. The anaerobic treatment technology has been greatly developed in the 40 s of the 20 th century, and the upflow anaerobic sludge blanket (Upflow Anaerobic Sludge Bed, UASB for short) technology developed in the Netherlands Lettinga in 1970 has been advanced. Although the anaerobic treatment process is applied earlier than the aerobic process, the aerobic process has been applied more widely for a long time due to the great success of the aerobic activated sludge process in the field of treating municipal domestic sewage. In recent years, along with the continuous progress of anaerobic technology, the application field of anaerobic technology is also becoming wider and wider. Compared with the aerobic treatment process, the anaerobic treatment process has the advantages of low treatment cost, less energy consumption, economical operation and management, high treatment load, flexible equipment and easy management. In UASB (upflow anaerobic sludge blanket) reactors, bottom fouling is a common problem, typically because of excessive accumulation of settled sludge during reactor operation, resulting in reduced permeability of the bottom sludge blanket. Such fouling requires periodic dredging to maintain proper operation of the reactor. However, there are also some adverse effects during dredging. Although the dredging operation is necessary, certain adverse effects are brought about, including problems of increased downtime, disturbance of a sludge bed, rising of operation cost, uneven distribution of inflow water, unstable hydraulic load and the like. Therefore, reasonable planning is needed during dredging, frequent dredging is avoided, and the design and operation of the reactor are optimized so as to reduce the frequency and influence of dredging. For example, the adverse effect of bottom fouling on UASB reactor operation can be effectively reduced by employing appropriate sludge removal systems, periodically monitoring sludge accumulation, designing a more efficient water flow distribution system, etc. Disclosure of utility model In order to overcome the defects, the utility model adopts the following technical scheme that.
