Efficient AOAS integrated sewage treatment device and process thereof

Abstract

The invention discloses an efficient AOAS integrated sewage treatment device and a process thereof. The efficient AOAS integrated sewage treatment device comprises a main body treatment facility, an aeration system and an automatic control system, wherein the main body treatment facility comprises an water feed pump at an inlet, and an anaerobic hydrolysis tank, a first stage reaction sedimentation tank, a second stage reaction sedimentation tank and an efficient flocculation and sedimentation tank, which are communicated in sequence through water flow; the aeration system comprises a blower, an air supply connecting pipeline and aeration plates respectively arranged at the bottoms of the first stage reaction sedimentation tank and the second stage reaction sedimentation tank. According to the device and the process disclosed by the invention, intermittent aeration, continuous water inflow, alternative aerobic environment and anaerobic environment are applied to a biochemical pool, thus the denitrification is obvious in the anaerobic environment; a reaction area and a sedimentation area are integrated in the biochemical pool and are divided by a division plate, so that no sedimentation tank needs to be additionally constructed, and no sludge reflux device is arranged; the biochemical reaction and sedimentation are integrated in the same pool structure, which breaks the inherent mode that two sedimentation tanks are separate from the biochemical pool, and thus the building is simpler; the operation of the inclined tube sedimentation tank is more stable.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, in particular to the technical field of sewage treatment, and specifically relates to an efficient AOAS integrated sewage treatment process and device. Background technique [0002] With the rapid development of the economy, the population of townships is constantly concentrated, the discharge of domestic sewage is increasing, and the environmental quality of townships is deteriorating. This has become an important factor restricting the healthy development of the township economy, and the treatment of domestic sewage in townships is becoming more and more urgent. [0003] The technologies currently used in township sewage treatment can be roughly divided into two categories: the first category is ecological treatment systems, which use land filtration, plant absorption and microbial decomposition to remove organic pollutants and a certain amount of nitrogen and phosphorus in wate...

AI Technical Summary

Problems solved by technology

The device and its method still belong to the improved AAO in essence, and need to set up a separate sedimentation tank, and its process route is the same as that of the traditional process; It is very easy to cause the inclined pipe to be blocked when it is in the pool, resulting in many problems such as poor operation
