Problems solved by technology

[0007] The biggest disadvantage of the existing integrated sewage treatment facilities in villages and towns is that the efficiency of nitrogen and phosphorus removal is not high enough. At the same time, although some villages and towns that use intelligent sewage treatment equipment have solved some problems caused by decentralized governance to a certain extent, However, there are still problems that the design and operation capacity of some sewage treatment facilities is much larger than the actual scale of receiving sewage, and the utilization rate is low.
Moreover, the intelligence of the monitoring equipment is low, and it can only judge the operation of the facility, but cannot judge the more complicated situation and the quality of the effluent water. Manual inspection and sampling are still required

Abstract

The invention provides a reactor for treating village and town sewage based on aerobic granular sludge and a sewage treatment method. The reactor comprises a water inlet system, a drainage system, an intermediate drainage system, a sludge discharge system, a gas supply system and an intelligent control system; the invention also relates to the sewage treatment method of the reactor. Compared with other village and town sewage treatment processes, the reactor for treating the village and town sewage based on the aerobic granular sludge has the advantages of more efficient biological nitrogen and phosphorus removal capacity, simple process structure, no need of a secondary sedimentation tank, small occupied area, good sludge settleability, easiness in mud-water separation, less mechanical equipment, strong impact load resistance, high automation and intelligence degree, simple operation and management, low operation energy consumption and the like.

Description

technical field [0001] The invention belongs to the field of sewage treatment; in particular, it relates to a reactor for treating village and town sewage based on aerobic granular sludge and a sewage treatment method. Background technique [0002] At present, the commonly used sewage treatment in villages and towns in my country is divided into biological treatment technology, ecological treatment technology, and combined treatment technology. Biological treatment processes include activated sludge process, biological contact oxidation, MBR and its combination process, among which the common activated sludge process is AO, AAO, SBR and its improved process. Ecological treatment technology is to use soil, plants, and microorganisms to purify sewage through filtration, absorption, and decomposition. Common methods include artificial wetlands, soil infiltration purification systems, and oxidation ponds. [0003] SBR is a batch activated sludge process, which operates in the s...
