Description

Technical Field

[0001] The invention relates to the technical field of sludge treatment, and in particular to a foldable combined anaerobic and aerobic combined sludge contact adsorption system. Background Art

[0002] Sludge treatment is the process of reducing, stabilizing and harmlessly treating sludge. The higher the degree of wastewater treatment, the more sludge residue that needs to be treated. Unless land treatment or sewage pools are used to treat sewage, general sewage treatment plants must be equipped with sludge treatment facilities. For modern sewage treatment plants, sludge treatment and disposal has become the most complex and costly part of the sewage treatment system operation. Sludge has different types according to its source, and the corresponding treatment methods are also different. Among them, the sludge generated in the garbage disposal process is the most difficult to treat.

[0003] Application number CN201710771202.X discloses a device for anaerobic ammonia oxidation denitrification process enhanced by sludge segmented reflow, which is a continuous flow reactor including a raw water storage tank, an inlet pump, a biochemical reactor, and a sedimentation tank, and the continuous flow reactor is connected to a PLC controller. The biochemical reactor includes an anaerobic zone, an aerobic zone, and an anoxic zone. The urban sewage raw water tank is connected to the inlet pipe of the biochemical reactor through the inlet pump, and the sewage passes through the anaerobic zone, aerobic zone, anoxic zone, and sedimentation tank connected in sequence through the inlet pipe. After the sedimentation tank is separated from the mud and water, the supernatant is discharged as effluent. In the anaerobic zone, the activated sludge adsorbs and degrades the organic matter in the influent to synthesize the internal carbon source; in the aerobic zone, by controlling the dissolved oxygen, the coupling of short-range denitrification and anaerobic ammonia oxidation is achieved, thereby improving the total nitrogen removal rate of the system.
