Embodiment 1

[0016] A sealed sewage biological treatment method, the sewage enters the plant treatment room in the sealed shell from the sewage inlet pipe on one side of the sealed shell, the plant treatment room is set inside the sealed shell, the microbial treatment room is set inside the plant treatment room, and the plant treatment room It forms an inner and outer nested water tank with the microbial treatment room. Aquatic emergent plants are planted in the plant treatment room. After staying in the plant treatment room for 1-2 hours, the sewage enters the microbial treatment room through the microbial treatment room inlet solenoid valve at the bottom of the microbial treatment room. , the sewage that stays in the microbial treatment chamber for 4-6 hours flows out from the outlet of the microbial treatment chamber at the top of the microbial treatment, and then enters the S-shaped baffle area through the downstream inflow solenoid valve and the water inlet of the S-shaped baffle area, ...

Abstract

The invention discloses a sealed type biological sewage treatment method. The method comprises the steps of enabling sewage to sequentially flow through a device consisting of a seal housing, a sewage inlet pipe, a plant treatment chamber, a microbial treatment chamber, a microbial treatment chamber water outlet, a microbial treatment chamber water inlet electromagnetic valve, a plant treatment chamber water inlet, an aeration blower, a forward-flow water inlet electromagnetic valve, a reverse-flow water inlet electromagnetic valve, an S-shaped baffling area, an S-shaped baffling area water inlet, an aeration pipe, a reverse-flow water outlet pipe, a forward-flow water outlet pipe, a water collecting area, a reverse-flow water outlet electromagnetic valve, a water collecting area outlet, a circulating water path water inlet I, a circulating water path water inlet II, a forward-flow water outlet electromagnetic valve, a circulating pump and an interception filter mesh, and then discharging. The sealed type biological sewage treatment method has the characteristics of low construction cost, stability in operation, small floor area and the like. The flexible transformation and combination of different flow paths and flows of internal water flow can be realized through controlling the opening and closing of all internal valves, the treatment manner is flexible, and the capacity of treating main pollutants, such as COD (Chemical Oxygen Demand), total phosphorus, total nitrogen and suspended substances, is relatively strong.

Description

technical field [0001] The invention relates to a sealed sewage biological treatment method, which belongs to the field of water treatment in environmental protection. Background technique [0002] Human activities will discharge a large amount of industrial, agricultural and domestic waste into the water, polluting the water body. Increasing water pollution has posed a major threat to human survival and has become a major obstacle to human health, economic and social sustainable development. Therefore, sewage treatment is an important issue related to the national economy and people's livelihood. [0003] Artificial biological treatment system has become a research hotspot in sewage treatment technology in recent years because of its large buffer capacity, good treatment effect, simple process, low investment and low operating cost. Artificial organisms are a comprehensive ecosystem including animals, plants, and microorganisms. On the premise of promoting a virtuous cycle...
