Sewage purification tank with composite biological purification wall

Abstract

The invention relates to the field of sewage treatment devices, and concretely relates to a sewage purification tank with a composite biological purification wall. The sewage purification tank comprises a driving structure, a storage structure, a mounting structure, a transmission structure, purification structures and a biological filler. The driving structure drives the transmission structure and the storage structure to rotate, so that the transmission structure drives the mounting structure to rotate, the mounting structure is conveniently lifted and mounted, and the mounting and dismounting efficiency and quality between the mounting structure and the storage structure are greatly improved; a plurality of purification structures for accommodating and storing the biological filler arearranged in the mounting structure, so the contact area between the biological filler in the purification structures and sewage is increased, the water flow speed is reduced, the contact time of the sewage and the biological filler is greatly prolonged, and the sewage treatment efficiency of the biological filler is high; and the mounting structure and the purification structures are more convenient and faster to mount and dismount, so the overhaul and maintenance efficiency and quality of the purification structures are greatly improved.

Description

technical field [0001] The invention relates to the field of sewage treatment devices, in particular to a sewage purification pool with a composite biological purification wall. Background technique [0002] In order to achieve equal flow and guidance of sewage, the inside of the purification tank is usually equipped with a plurality of staggered barrier walls, and the sewage flows in the flow channel formed by the barrier walls, and the purification treatment is completed by the action of activated sludge; With the continuous improvement of sewage treatment standards and requirements, the existing activated sludge purification process can no longer meet the high standard requirements. Therefore, a new standard improvement technology has been proposed in the industry: by adding suspendable biological fillers in the biochemical tank, The formation of biofilm on the biological filler can form a joint process with activated sludge, which can greatly increase the biomass in the ...

Problems solved by technology

[0002] In order to achieve equal flow and guidance of sewage, the inside of the purification tank is usually equipped with a plurality of staggered barrier walls, and the sewage flows in the flow channel formed by the barrier walls, and the purification treatment is completed by the action of activated sludge; With the continuous improvement of sewage treatment standards and requirements, the existing activated sludge purification process can no longer meet the high standard requirements. Therefore, a new standard improvement technology has been proposed in the industry: by adding suspendable biological fillers in the biochemical tank, The formation of biofilm on the biological filler can form a combined process with activated sludge, which can greatly increase the biomass in the purification tank, strengthen the efficiency of secondary biological treatment of sewage, and achieve high-efficiency deep denitrification

[0003] However, since the biological filler is suspended in the sewage, it will drift around with the water flow, which is not easy to recycle and control. Therefore, a biological purification wall that integrates the biological filler into the partition wall has appeared on the market, which can remove the biological filler from the biological filler. The purification ability and the splitting and equalizing ability of the partition wall play a comprehensive role. After the partition wall is manufactured, it is not convenient to quickly separate from the purification tank, and the efficiency of maintenance is low. The contact time of the biofiller is extremely limited, and the biological purification treatment of the sewage by the biological filler is not sufficient, so that the purification effect of the sewage is poor.
