Wherein: 1-intake pump；The aerobic MBBR reaction tank of 2-；3-floating stuffing；4-aeration head；5-aerator；6-river bottom mud fermentation coupling denitrification pond；7-agitator；8-enters dredge pump；9-second pond；10-effluent recycling pump；11-sludge reflux pump.
Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is further described.
As shown in Figure 1.
The device of sewage and bed mud in a kind of Combined Treatment black-odor riverway, including the aerobic MBBR reaction tank 2 adjoined each other and river bottom mud fermentation coupling denitrification pond 6.Described aerobic MBBR reaction tank 2 introduces river sewage by intake pump 1, and is connected with river bottom mud fermentation coupling denitrification pond 6 by overfall.Being provided with floating stuffing 3 in described aerobic MBBR reaction tank 2, it grows biomembrane, the Organic substance in the river sewage that can be introduced into is degraded, and the mineralized nitrogen in water is become nitrate nitrogen.Further, it is additionally provided with multiple aeration head 4 being connected with aerator outside pond 5 in this aerobic MBBR reaction tank 2, it is possible to increase amount of oxygen therein, improves the efficiency of reaction.The water processed through described aerobic MBBR reaction tank 2 flows in described river bottom mud fermentation coupling denitrification pond 6 through overfall, passes through to introduce river bottom mud into dredge pump 8 simultaneously.The fermentation of described river bottom mud is provided with acidogenic bactria and denitrifying bacteria in coupling denitrification pond 6, Organic substance in river bottom mud can be converted into volatile acid, and denitrifying bacteria is using volatile acid as carbon source, using the nitrate nitrogen in the water outlet of aerobic MBBR reaction tank 2 as electron acceptor, nitrate nitrogen is changed into nitrogen and removes.Further, the fermentation of described river bottom mud is additionally provided with agitator 7 in coupling denitrification pond 6, can promote the mixing of bed mud.Meanwhile, the anti-nitration reaction occurred in this river bottom mud fermentation coupling denitrification pond 6 can produce basicity, and the pH in reactor can be made to be in alkali condition, so that heavy metal and phosphate in bed mud are removed by producing chemical precipitation.Described river bottom mud fermentation coupling denitrification pond 6, by being connected with second pond 9 from head piece, makes the water outlet after process certainly flow into second pond 9 and precipitates.Further, part water outlet is transmitted back to aerobic MBBR reaction tank 2 also by pipeline and effluent recycling pump 10 by described second pond, can remove ferment in river bottom mud fermentation coupling denitrification pond 6 Organic substance and ammonia nitrogen that produce further, thus reducing the total nitrogen of water outlet.Meanwhile, partial sludge is transmitted back in river bottom mud fermentation coupling denitrification pond 6 also by pipeline and sludge reflux pump 11 by described second pond 9 respectively, it is prevented that sludge loss, it is ensured that in bed mud fermentation coupling denitrification pond 6, sludge concentration stablizes.
Workflow of the present utility model is:
1. black-odor riverway sewage is squeezed in aerobic MBBR reaction tank by river sewage intake pump, aeration head and aerator are to aerobic MBBR reaction tank oxygen supply, on floating stuffing in aerobic MBBR reaction tank, Organic substance is decomposed by the organisms use oxygen of growth, and is nitrate nitrogen by mineralized nitrogen.
2. the water outlet overflow of aerobic MBBR reaction tank enters river bottom mud fermentation coupling denitrification pond.In river bottom mud fermentation coupling denitrification pond, denitrifying bacterium utilizes the carbon source that the nitrate nitrogen in aerobic MBBR reaction tank water outlet and river bottom mud fermentation produce to carry out denitrification, nitrate nitrogen changes into nitrogen and removes.Can be fermented by the river bottom mud pH in coupling denitrification pond of the basicity produced in denitrification process rises to about 8 ~ 9, makes river bottom mud fermentation coupling denitrification pond be in alkaline environment.When alkaline environment, heavy metal ion and phosphate chemical in river bottom mud precipitate, and make bed mud be stablized.
3. the water outlet in bed mud fermentation coupling denitrification pond is from flowing into sedimentation in secondary sedimentation tank.A part in second pond supernatant is discharged, and another part delivers to aerobic MBBR reaction tank by effluent recycling blowback, can remove ferment in river bottom mud fermentation coupling denitrification the pond Organic substance and ammonia nitrogen that produce further, thus reducing the total nitrogen of water outlet further.
4. the part in second pond mud is as excess sludge discharge, and another part is recycled to bed mud fermentation coupling denitrification pond by sludge reflux pump, can prevent sludge loss, it is ensured that stablizing of bed mud fermentation coupling denitrification pond sludge concentration.
This utility model is not directed to part and all same as the prior art prior art maybe can be adopted to be realized.
