Problems solved by technology

[0003] The area of ​​the fillers set in the existing biological contact oxidation tank technology is mostly not large, and the contact between the biofilm and the sewage is uneven, and the biofilm hanging on the fillers cannot be well used to treat the sewage, resulting in biological The life cycle of the membrane is not long, and the space in the pool is wasted

Embodiment

[0022] Such as figure 1 Shown is a preferred solution of the present invention, a multi-layer biological contact oxidation tank, including a tank body 1, a multi-layer packing plate 2 is provided in the tank body 1, and a sloping plate sedimentation area is provided at the bottom of the tank body 1 3. The multi-layer packing plate 2 can make reasonable use of the space in the pool body 1, so that the sewage flows in one direction in the pool body 1, fully contacts with the biofilm on the packing plate 2 to remove organic matter in the water, and the lower part of the pool body 1 The inclined plate sedimentation area 3 is equipped to collect the particles that sink due to the sedimentation in the sewage, reduce the SS index of the effluent, and also combine the activated sludge aeration method with the biological contact oxidation method to achieve the purpose of efficient sewage purification.

[0023] Further, the three sides of the packing plate 2 are all fixed on the inner w...

Abstract

The invention discloses a multi-layer biological contact oxidation pool, which comprises a pool body, filler plates and an inclined plate sedimentation zone. Layers of staggered filler plates are disposed in the pool body, the bottom of the pool body is equipped with the inclined plate sedimentation zone, the lower part of the pool body is provided with an aeration pipe, the outer wall of the pool body is provided with a blower, and the blower is communicated with the aeration pipe. Aeration operation is carried out through aeration micropores set on the aeration pipe, the lower part of the pool body is equipped with a water inlet pipe and the upper part of the pool body is equipped with a water outlet pipe. The pool provided by the invention combines activated sludge process and biological contact oxidation process to conduct sewage treatment operation, and has high purification efficiency and hydraulic load.

Description

technical field [0001] The invention belongs to sewage treatment equipment, in particular to a multi-layer biological contact oxidation pond. Background technique [0002] The biological contact oxidation method is an efficient water treatment process for purifying organic wastewater based on the biofilm attached to the carrier (commonly known as the filler); the biofilm method with the characteristics of the activated sludge method combines the activated sludge method and the biological The advantages of the membrane method; under biochemical conditions, no matter it is applied to the treatment of industrial wastewater, aquaculture sewage, and domestic sewage, it has achieved good economic benefits; It is widely used in sewage treatment systems in various industries due to its convenient management. [0003] The area of ​​the fillers set in the existing biological contact oxidation tank technology is mostly not large, and the contact between the biofilm and the sewage is u...
