Decontamination and deodorization system for sewage and odor and use method thereof

Abstract

The invention discloses a decontamination and deodorization system for sewage and odor and a use method thereof. The decontamination and deodorization system comprises a closed reaction tank which is divided into two parts including an anaerobic region and an aerobic region, which are communicated with each other, wherein the anaerobic region is connected / communicated with a sewage discharge port in an external space through a sewage discharge pipeline, the aerobic region is provided with a biological filler reaction device, is connected / communicated with the anaerobic region and the sewage discharge port in the external space through an exhausting pipeline, is connected / communicated with the outside through a gas transmission pipeline, and is connected / communicated with a water supplying system in the external space through a water transmission pipeline, and the gas outlet of the exhausting pipeline is inserted into the biological filler reaction device in an extending manner. The decontamination and deodorization system for the sewage and the odor and the use method thereof have the beneficial effects of quick effect on decontamination and deodorization, no secondary pollution, no chemical additives in a whole process, no generation of sludge, waste, odor and the like, outlet water recovering, water resource recycling, simultaneous treatment on the sewage and the odor, little floor space, high treatment efficiency, simplicity and convenience in operation and management, low energy consumption, no leakage, long service life of equipment, low investment, and good benefit.

Description

technical field [0001] The invention relates to a decontamination and deodorization system, which belongs to the technical field of biological purification, in particular to a decontamination and deodorization system for sewage odor and a use method thereof. Background technique [0002] With the development of urbanization and the increase of urban population, in order to reduce the pressure of traditional ground public transportation, many cities have embarked on the development of underground rail transportation. From 1965 to now, about 47 cities across the country have built or are building subways. Because the subway space is an underground confined space with poor air flow, the toilet odor and hygiene problems have not been well resolved, and have become a common problem all over the world. On the other hand, citizens have very strong demands on the construction of toilets in the subway. No matter from the perspective of people-oriented, or from the perspective of urb...

AI Technical Summary

Problems solved by technology

Since the subway space is an underground confined space with poor air mobility, the odor and hygiene problems in the toilets have not been well resolved, and have become a common problem all over the world.

[0003] At present, some cities in China have set up toilets in confined spaces such as subways, but the effect is not ideal

The reason is that the current wastewater odor treatment technology has defects, such as long treatment time, low efficiency and poor effect, which directly affect the environmental sanitation and air quality of the underground space.

[0004] Although some cities use externally added microorganisms for treatment, because the added microbial populations are not highly targeted, their vitality is poor, and the cost is high (100,000 to 150,000 yuan per ton), a single toilet needs to add 15 tons of external microorganisms per day, which is equivalent to 10,000 yuan per day. The investment is as high as 1.5-2.25 million yuan, the cost is very high, the effect is not ideal, and the management is inconvenient, so it cannot be widely promoted

[0005] However, the traditional sewage treatment methods are either unable to treat the odor, or adopt the independent treatment method of gas-water separation, which covers a large area, high cost, and low treatment efficiency, and is not suitable for the sewage and odor of the toilet sewage system of underground buildings. Gas treatment; at the same time, the traditional activated sludge method has the problem of difficult sludge treatment, which will bring more and greater problems to underground buildings with limited space
