specific Embodiment approach 1

[0020] see figure 1 , the water to be treated enters the reaction zone 7 from the water inlet device 2, and makes the inlet water evenly distributed at the bottom of the reactor body 1. The aeration device 3 aerates the reaction zone 7 to make the reaction zone 7 in an aerobic state, and cooperates with the three-phase separator 6 on the upper part of the reaction zone 7 to form the flow state and conditions required for the formation of aerobic granular sludge. The aerobic sludge in the reaction zone 7 reacts with the water to be treated, and after several months of cultivation, aerobic granular sludge is formed in the reaction zone 7. The water to be treated reacts with the aerobic granular sludge and flocculent sludge in the reaction zone 7, and enters the three-item separator 6 after being purified. The three-phase separator 6 makes the aerobic sludge return to the reaction zone 7, so that the reaction zone 7 can retain a large amount of aerobic sludge, which is beneficia...

specific Embodiment approach 2

[0021] see figure 2 , In this embodiment, a liquid seal 9 is set behind the three-phase separator 6, and the others are the same as the first embodiment.

specific Embodiment approach 3

[0022] see image 3 , this embodiment is to install inclined tubes or inclined plates 10 in the sedimentation area 8, and the others are the same as the first or second embodiment.

Abstract

The invention discloses a water treatment technology. An aerobic granular sludge reactor comprises a reactor body, a water intake device, an aeration device, a sludge discharge device, an effluent collecting device, a three-phase separator, a reaction zone and a settling zone. Aeration is carried out in the reaction zone to form aerobic granular sludge. By the aerobic granular sludge reactor, stable aerobic granular sludge can be formed, and an aerobic granular sludge technology can be applied in engineering practice.

Description

technical field [0001] The invention belongs to a water treatment process, in particular to an aerobic granular sludge reactor. Background technique [0002] Aerobic Granular Sludge was first discovered in 1911 by Mishillla et al. Aerobic granular sludge is a granular activated sludge formed by microbial self-coagulation. Compared with ordinary activated sludge, it has the ability to increase the reactor sludge activity and biomass concentration, reduce the discharge of excess sludge, and is not easy to Sludge bulking, good settling performance, strong impact resistance, ability to withstand high organic loads, and the integration of different types of microorganisms (aerobic, facultative and anaerobic microorganisms) have become research hotspots for scholars at home and abroad. Research results in recent years have shown that aerobic granular sludge has a good removal effect on organic matter, nitrogen, phosphorus and heavy metals. However, the aerobic granular sludge te...
