Problems solved by technology

However, when the upward flow of water and rising air bubbles agitate the biomass flocs and particles, the liquid level may fluctuate and turbulence may be generated, which in turn may cause excess anaerobic bacteria to be flushed from the overflow, thereby greatly Limits the load capacity of the anoxic pool

Embodiment 1

[0044] This embodiment discloses a circulating high-efficiency upgrading system, or a water treatment system, or a waste water treatment system. Without causing conflicts or contradictions, the overall and preferred implementations of other embodiments / or part of the content may be used as a supplement to this embodiment.

[0045] According to a preferred embodiment, the system may include at least one of the regulating pond A, the anoxic pond B, the aerobic pond C, the sedimentation pond D and the clear water pond E. A loop oxidation reactor LR may be arranged in the aerobic pool C. The water in the adjustment pool A can be filtered into the anoxic pool B through the grid. The aerobic tank C transfers the water in the anoxic tank B to the sedimentation tank D after efficient upgrading. At the same time, the nitrifying liquid in the aerobic tank C and the sludge in the sedimentation tank D can circulate back to the anoxic tank B. The clear water in the sedimentation tank D...

Abstract

The invention relates to a circulation type high-efficiency standard-improving system. The system at least comprises an anoxic tank, wherein the anoxic tank comprises a reaction vessel, a first liquidinlet used for introducing liquid from a regulating tank into the reaction vessel during operation, a second liquid inlet used for introducing liquid from an aerobic tank into the reaction vessel during operation, a liquid outlet, at least one gas aggregator, at least one gas-liquid separator, at least one ascending pipe and a descending pipe, wherein at least one gas aggregator is connected to the gas-liquid separator through the at least one ascending pipe, at least one gas aggregator is located in the liquid of the anoxic tank to collect gas generated in the liquid and transmit the gas tothe gas-liquid separator through the ascending pipe, and the descending pipe is connected to the gas-liquid separator to transmit the liquid in the gas-liquid separator downwards to the middle or bottom of the reaction vessel. The system provided by the invention can effectively reduce excess anaerobic bacteria flushed out from an overflow opening to stabilize load capacity of the anoxic tank.

Description

technical field [0001] The invention relates to the field of water treatment and the ecological environment protection industry, in particular to the prevention and control of water pollution and the advanced treatment of waste water, and in particular to a circulation-type high-efficiency upgrading system. Background technique [0002] At present, anaerobic biological treatment of wastewater refers to the process of decomposing and converting various complex organic substances in wastewater into methane and carbon dioxide through the action of anaerobic microorganisms and / or facultative microorganisms under the condition of no molecular oxygen, also known as Anaerobic digestion. Anaerobic digestion technology is one of the most important biomass energy utilization technologies. It converts solid organic matter into dissolved organic matter, and then converts the energy stored in waste into biogas for combustion or power generation, so as to realize the utilization of resour...
