Problems solved by technology

In order to meet the discharge standards incorporated into the sewage pipe network, under normal circumstances, the mainstream process route of upstream enterprises for the treatment of high-concentration organic wastewater is: grille + sedimentation + regulating tank + anaerobic reactor + aerobic biochemical + secondary sedimentation tank process , when the effluent discharge standard requires the network to be collected, pretreatment, anaerobic, aerobic biochemical, and mud-water separation units are all indispensable. For enterprises, the one-time investment cost is high and the later operation and management and maintenance costs are high. Upstream enterprises bring great economic burden
[0003] The most costly link for enterprises to treat high-concentration organic wastewater is in the aerobic biochemical treatment section, which requires aerobic aeration and high power consumption

Embodiment 1

[0041] The present invention is applied to a certain brewery wastewater treatment plant.

[0042] The treatment plant is designed to handle 7000m 3 / d, its water quality characteristics are: high COD, TN, TP.

[0043] See Table 1 for influent and effluent water quality:

[0044] Table 1

[0045] index COD (mg / L) TN (mg / L) TP (mg / L) SS(mg / L) Influent water quality 1500-2000 50-90 8-12 260-700 Water quality ＜350 ＜40 ＜1.2 ＜10

[0046] It can be known from Table 1 that the wastewater index of the enterprise can be stably reached the sewer discharge standard by adopting the present invention to treat the waste water of the enterprise. COD removal rate> 82.5%, TN removal rate> 55.6%, TP removal rate> 90%, SS removal rate> 98.6%. The invention greatly saves the production cost of the enterprise, and at the same time plays a positive role in energy saving and consumption reduction of the enterprise. The stable pre-treatment effluent is then...

Abstract

The invention discloses a sewage treatment system and a sewage treatment process based on super-effect separation, and relates to the technical field of water treatment. The technical problems that inthe prior art, the high-concentration organic wastewater treatment process is complex, and the treatment cost is high are solved. The system comprises a pretreatment system, an anaerobic reactor anda super-effect separation system, which are connected in sequence; the super-effect separation system comprises a mixing tank, a magnetic seed loading tank, a flocculation reaction tank and an inclined tube sedimentation tank; a mud scraper is arranged in the inclined tube sedimentation tank; the bottom of the inclined tube sedimentation tank is connected with a sludge return pipe, and the other end of the sludge return pipe is connected with the magnetic seed loading tank; the sludge return pipe is used for feeding the coagulated flocs containing the magnetic seeds into the magnetic seed loading tank; the bottom of the inclined tube sedimentation tank is also connected with a residual sludge return pipe, and the other end of the residual sludge return pipe is sequentially connected with ahigh-speed shearing machine and a magnetic separator. The sewage treatment system disclosed by the invention is good in treatment effect, can reach the sewer discharge standard, and is more energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a pretreatment process for high-concentration organic wastewater, and in particular to a sewage treatment system and process based on super-efficient separation. Background technique [0002] With the rapid development of my country's economy and the continuous advancement of industrialization and urbanization, the contradiction between the sharp increase in water consumption and the problem of water pollution has become increasingly prominent. In the context of environmental protection, the front-end treatment requirements for high-concentration organic wastewater are becoming more and more stringent. The discharge of high-concentration wastewater from upstream enterprises into the sewage pipe network is an important prerequisite and guarantee for the stable operation and discharge of downstream sewage treatment plants. In order to meet the discharge standards incorporat...
