Embodiment

As shown in Figure 1, 2, the decontamination and deodorant system of sewage foul smell of the present invention, include enclosed reaction tank, and described reaction tank is divided into two, includes the anaerobic zone 1 and the aerobic zone 2 that communicate.

Above-mentioned anaerobic zone 1 is divided into two with isometric the first anaerobic zone 11 and the second anaerobic zone 12, between the first anaerobic zone 11 and the second anaerobic zone 12, by the first overflow pipe 14, keep being communicated with, and the first anaerobic zone 11 connects by blow-off line 13 and space outerpace sewage draining exit, between the second anaerobic zone 12 and aerobic zone 2, by the second overflow pipe 15, keep being communicated with, to receive the sewage of storage space outerpace discharge.

Above-mentioned aerobic zone 2 is provided with biologic packing material reaction unit 3, and aerobic zone 2 is by bleed line 21 and anaerobic zone 1 with the space outerpace venting port connects and the air outlet of bleed line 21 is extended and inserted in biologic packing material reaction unit 3, by air delivering pipeline 22 and outside, connect, by hydraulic pipe-line 23 and the waterworks of space outerpace, connect, thereby receive the sewage that 1 overflow of storage anaerobic zone comes and sewage is carried out to the biopurification processing, for recycle again, the foul smell of simultaneously anaerobic zone 1 and space outerpace being pumped carries out the deodorizing processing, be beneficial to discharge to purify foul smell.

Described biologic packing material reaction unit 3 includes biologic packing material 31 and microbubble aeration parts, and wherein: above-mentioned biologic packing material 31 is loaded in aerobic zone 2 inside, and each biologic packing material 31 is flower group ball-like structure, has some curling folds space; Above-mentioned microbubble aeration parts include fine bubble diffuser 32 and gas blower 33, and fine bubble diffuser 32 is layed in the interior end of aerobic zone 2, and gas blower 33 connects by air blast pipeline 34 and fine bubble diffuser 32, and air blast pipeline 34 is provided with electrically-controlled valve 35.Biologic packing material 31 has been simulated the bending in river course, natural environment characteristics microminiaturization by large-scale tortuous channel, in sewage treatment process, the fold because the surface-area of this biologic packing material 31 is large, the speed that can make the effluent stream warp slow down and the residence time long, more the microorganism growth breeding provides advantage, makes it more easily form microbial film, and the clearance of the pollutent in sewage is improved greatly.

Described bleed line 21 is provided with vacuum fan 24, take and guarantees that anaerobic zone 1 and space outerpace to the gas flow of aerobic zone 2 is uniflux.

As shown in Figure 3, the using method of the decontamination and deodorant system of above-mentioned sewage foul smell, it comprises the following steps: S1, biologic packing material reaction unit carry out microorganism culturing, at aerobic zone 2, form the microorganism species mother liquor; S2, sewage enter anaerobic zone 1 from space outerpace 4 through blow-off line 13, anaerobic zone 1 is delivered to aerobic zone 2 by the overflow mode by sewage, experienced anaerobism to aerobic process, and by microorganism, sewage is carried out to the biopurification processing at aerobic zone 2, the water body after purification outputs to space outerpace 4(as underground lavatory by hydraulic pipe-line 23) recycling; S3, foul smell deliver to the biologic packing material reaction unit of aerobic zone 2 and by biologic packing material reaction unit adsorption cleaning through bleed line 21 from anaerobic zone 1 and space outerpace 4 by the mode of pumping, being discharged by air delivering pipeline 22 without odour after purification.

In described S1 step, microorganism culturing adopts the mode of intermittent water inflow, continuous aeration, the nutritive substance as microorganism growth breeding to the aerobic zone sewage effluent at regular time and quantity, make microorganism in growth in half-full semistarvation state, and then improve microorganism look for food power and biological activity.Preferably, the flooding quantity of described aerobic zone every day is biological packing volume 2~3 times.The culture of microorganism that the present invention adopts can keep the top of microorganism at activity curve, and due to intermittent water inflow, slow down the accretion rate of microorganism, extended the life of microorganism, avoided the discharge of a large amount of metabolism pollutents of producing due to microbial death; It is main adhering to the microorganism such as nitrifier during normal operation, can effectively the degrade ammonia nitrogen in water, TP and organic pollutant etc., and each cube of filler per hour can be processed 50~100kg sanitary wastewater at present, and foul smell was thoroughly eliminated at 30~60 seconds.

Described biologic packing material reaction unit adopts fine bubble diffuser, by gas blower, it is carried out to continuous air feed, produce the microbubble that diameter is little, density is high, being conducive to water body fully contacts and absorbs it, thereby improved the utilization ratio of oxygen, owing to adopting the frequency conversion gas blower to be controlled, current consumption and the noise of gas blower be can farthest reduce simultaneously, less energy-consumption and high-level efficiency realized.

The present invention utilizes ecological principle and Ecological Control theory, sewage and odor treatment are regarded as to a system, give full play to the powerful capacity of decomposition of microorganism to pollutent in sewage, and artificial regulatory measure, adopt " online screening, the online cultivation, on-line preconcentration " method, create an environment that is conducive to the aerobic beneficial microorganism growth cultivations such as nitrifier, pollutent is treated as to its growing nutrient material, be converted into nitrogen, carbonic acid gas and water, control mode by microorganism in hungryization or half hungryization system, further improve activity and the purity of its population, built up one with strong points, the sewage stench processing system that degradation capability is large.

The present invention is not limited to above-mentioned embodiment, if various changes of the present invention and modification are not broken away to the spirit and scope of the present invention, if, within these changes and modification belong to claim of the present invention and equivalent technologies scope, the present invention also is intended to comprise these changes and modification.
