Continuous water inlet and outlet multi-unit aerobic granular sludge reactor

Abstract

The invention discloses a continuous water inlet and outlet multi-unit aerobic granular sludge reactor. The reactor comprises a base, a reactor body is fixedly mounted at the upper end of the base, a first reaction tank is fixedly mounted at the left end of the interior of the reactor body, a second reaction tank is fixedly mounted in the middle of the interior of the reactor body, a third reaction tank is fixedly mounted at the right end in the reactor body, and the first reaction tank, the second reaction tank and the third reaction tank are communicated through openings of diversion partition walls. According to the continuous water inlet and outlet multi-unit aerobic granular sludge reactor, continuous water inlet and outlet can be achieved, the intermittent flow operation mode of the aerobic granular sludge process is improved, the nitrogen and phosphorus removal function of a system is enhanced by adopting the concept of sludge layer water inlet, meanwhile, the water inlet and outlet working condition of the same unit is controlled within a short time, short flow is fully avoided, the effluent quality is guaranteed, and a new choice is provided for application of the aerobic granular sludge process in the fields of municipal wastewater treatment and the like.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a continuous water inflow and outflow multi-unit aerobic granular sludge reactor. Background technique [0002] Aerobic granular sludge has been widely studied by domestic and foreign scholars as a more sustainable and efficient sewage treatment method in the past 20 years. Aerobic granular sludge is a kind of microbial aggregation with self-agglomeration, compact structure and excellent sedimentation performance. Its formation improves the floc structure of activated sludge, enhances the biological density and sludge volume, and enhances the biochemical reaction capacity of the system and the clarification effect of sludge settlement. Compared with the traditional activated sludge method, the aerobic granular sewage Sludge can effectively increase the concentration of reactor sludge, and has obvious advantages in increasing volume load and improving settlement performan...
