Technical field
The utility model belongs to field of environment engineering technology, is specifically related to a kind of MBR reactor utilizing rubbish from cooking to improve sewage water denitrification effect.
Background technology
Along with villages and small towns problem of environmental pollution increasingly sharpens, the strength disposal of villages and small towns sewage continues to increase, and MBR reactor obtains as a kind of scattering sewage treatment facility and applies more and more widely.But in many areas, villages and small towns sewage especially sanitary sewage often not enough, the carbon-nitrogen ratio of carbon source is lower than biological treatment requirement, inhibit denitrification process, reduce denitrification effect, effluent quality is poor.Therefore need additional carbon to improve water inlet carbon-nitrogen ratio.The business carbon source that municipal wastewater treatment plant is conventional comprises sodium acetate and methyl alcohol etc., but because its cost is higher or have certain risk, difficult management, therefore and be not suitable for area, villages and small towns.And rubbish from cooking is a kind of safe carbon source cheap and easy to get, after broken hydrolysis rate fast, effectively can discharge dissolved organic matter, thus improve water inlet carbon-nitrogen ratio, promote the denitrification effect of reactor.The synchronous processing of rubbish from cooking and sewage can also realize kitchen waste reduction, reduces noxious waste pollution.
Summary of the invention
The purpose of this utility model is to provide a kind of MBR reactor utilizing rubbish from cooking to improve sewage water denitrification effect, and it utilizes rubbish from cooking to improve sewage water denitrification effect as additional carbon, simple to operate, do not increase occupation of land, effluent quality is excellent.
The utility model is achieved through the following technical solutions: a kind of MBR reactor utilizing rubbish from cooking to improve sewage water denitrification effect, and described MBR reactor is divided into oxygen-starved area and aerobic zone, and described oxygen-starved area is communicated with bottom aerobic zone; Be fixed with destroyer above described oxygen-starved area, be separated cage basket and be suspended to inside, oxygen-starved area by hook; Connected by pipeline bottom described destroyer and be separated cage basket, the broken thing in destroyer is entered by pipeline and is separated in cage basket; Agitator is provided with in described oxygen-starved area; Be provided with membrane module and aeration tube in described aerobic zone, membrane module is positioned in the middle part of aerobic zone, and aeration tube is positioned at bottom aerobic zone, and aeration tube is positioned at below membrane module.
In the utility model, the active sludge in aerobic zone is delivered to oxygen-starved area by reflux pump.
In the utility model, described membrane module top connects water pump by pipeline.
In the utility model, described aeration tube connects gas blower by pipeline.
The beneficial effects of the utility model are: add rubbish from cooking as additional carbon, the dissolved organic matter discharged after fragmentation, separation enters reactor oxygen-starved area and enhances denitrification, effectively can improve the denitrification effect of reactor, significantly reduce water outlet total nitrogen concentration, realize standard water discharge discharge, the utility model can realize the synchronous processing of sewage and rubbish from cooking, simple to operate, do not increase occupation of land, effluent quality is excellent.

Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated, but embodiment of the present utility model is not limited only to this.
Embodiment: as shown in Figure 1, a kind of MBR reactor utilizing rubbish from cooking to improve sewage water denitrification effect, form primarily of destroyer 4, separation cage basket 6, oxygen-starved area 2 and aerobic zone 8, destroyer 4 is fixed on above oxygen-starved area 2, is separated cage basket 6 and is suspended in inside, oxygen-starved area 2 by hook 7.Broken thing is entered by pipeline 5 and is separated in cage basket 6, be separated cage basket 6 have retain macrobead solid can make simultaneously dissolved matter through function.Agitator 3 is set in oxygen-starved area 2.Membrane module 9 and aeration tube 10 are set in aerobic zone 8.Oxygen-starved area 2 is communicated with bottom aerobic zone 8, and utilizes reflux pump 13 that the active sludge in aerobic zone 8 is delivered to oxygen-starved area 2.
Working process of the present utility model is: rubbish from cooking added by above destroyer 4, broken thing is entered by pipeline 5 and is separated in cage basket 6, the dissolved organic matter that broken thing discharges enters oxygen-starved area 2 and improves into water carbon-nitrogen ratio thus the denitrification effect enhancing reactor, the normal operation being separated and not affecting reactor in cage basket 6 then stayed by remaining macrobead solid, is separated the steady running of cage basket 6 realization response device by periodic cleaning.Sewage enters oxygen-starved area 2 by water inlet pipe 1, and oxygen-starved area 2 arranges agitator 3 makes active sludge keep even suspension state, and the active sludge in oxygen-starved area 2 is removed the partial organic substances in intaking, by anti-nitration reaction, nitric nitrogen is transformed into nitrogen simultaneously.The bottom connected entrance of mud mixed liquid through oxygen-starved area 2 enters aerobic zone 8.Arrange aeration tube 10 bottom aerobic zone 8, aeration tube 10 connects gas blower 12, as the active sludge intermixture oxygen supply in aerobic zone 2, produces suitable face scouring intensity simultaneously.In aerobic zone 8, active sludge is removed entering organic matter of water further, by nitration reaction, ammonia nitrogen and organonitrogen is transformed into nitric nitrogen simultaneously, and passes through reflux pump 13 by mixed-liquor return to oxygen-starved area 2.Membrane module 9 to be arranged in aerobic zone 8 and to connect water pump 11, and membrane module 9 is by active sludge intermixture solid-liquid separation, and water outlet is by going out water pump 11 suction-discharge.
Near Shanghai City, certain Rural areas sewage chemical oxygen demand (COD) concentration is 60 ~ 80 mg/L, and total nitrogen concentration is 35 ~ 42 mg/L, and adopt traditional MBR reactor water outlet total nitrogen concentration to be 30 ~ 35 mg/L, denitrification effect is poor.After have employed the utility model, within every 3 days, add 600 g rubbishes from cooking, water outlet total nitrogen concentration is 12 ~ 15 mg/L, and ammonia nitrogen concentration lower than 50 mg/L lower than 1 mg/L, COD concentration, is stablized and reached one-level A Effluent criteria.Prove that the utility model can significantly improve sewage water denitrification effect by utilizing rubbish from cooking.
