Abstract
一种以生活污水作为碳源的驯化可共代谢降解2,4,6‑三氯酚的微生物方法，属于污水生物处理技术领域。本发明将SBR作为主体反应装置，接种城镇污水处理厂二次沉淀池活性污泥，并采用生活污水作为SBR反应器的共代谢碳源，人工配置的2,4,6‑三氯酚为待处理废水。即，先以生活污水作为碳源培养微生物，待活性污泥恢复活性之后，开始按梯度浓度引入含2,4,6‑三氯酚的配水至SBR进行曝气驯化，获得具有一定降解能力的活性污泥，系统可以稳定运行，并去除80mg/L以上的2,4,6‑三氯酚。本发明采用生活污水作为共代谢碳源，不依靠人工投加其他碳源，减少了实际处理含酚废水的处理成本，并且由于生活污水碳源种类丰富，在一定程度上促进了微生物对氯酚的降解，相比投加单一碳源更有优势，对处理实际含酚废水具有指导意义。A microbial method for domestication and co-metabolism degradation of 2,4,6-trichlorophenol using domestic sewage as a carbon source belongs to the technical field of sewage biological treatment. The invention uses SBR as the main reaction device, inoculates the activated sludge in the secondary sedimentation tank of the urban sewage treatment plant, and uses the domestic sewage as the co-metabolized carbon source of the SBR reactor, and the artificially configured 2,4,6-trichlorophenol is to be Treat wastewater. That is, the microorganisms are first cultivated with domestic sewage as a carbon source, and after the activated sludge is restored to its activity, the water distribution containing 2,4,6-trichlorophenol is introduced into the SBR according to the gradient concentration for aeration and domestication, and a certain degradation ability is obtained. Activated sludge, the system can run stably and remove 2,4,6-trichlorophenol above 80mg/L. The method adopts domestic sewage as a co-metabolized carbon source, does not rely on artificial addition of other carbon sources, reduces the treatment cost of actual treatment of phenol-containing wastewater, and because the domestic sewage is rich in carbon sources, to a certain extent, it promotes microbial p-chlorophenol Compared with the addition of a single carbon source, the degradation of phenol is more advantageous, and it has guiding significance for the treatment of actual phenol-containing wastewater.
Description
Technical Field
The invention belongs to the field of biological sewage treatment, and particularly relates to a microbial method for domesticating domestic sewage as a carbon source and co-metabolizing and degrading 2,4, 6-trichlorophenol, which can be used for treating 2,4, 6-trichlorophenol-containing wastewater in the environment.
Background
Trichlorophenol is widely applied to industrial production, and factory effluent often contains high-concentration trichlorophenol due to substandard discharge. 2,4, 6-trichlorophenol is taken as a typical industrial raw material, and the application range is wider. Trichlorophenols have been listed as a priority for controlling contaminants because of the "trio" effect that trichlorophenols can cause.
At present, co-metabolism is widely used in wastewater treatment as a biological treatment technology capable of effectively removing toxic pollutants. The co-metabolism refers to that under the condition that the microorganism can not rapidly degrade or degrade toxic organic matters, one or more harmless organic matters which can be rapidly degraded or utilized by the microorganism are added into a degradation system, and the organic matters and the toxic organic matters can be degraded and mineralized by the microorganism together, so that the method for rapidly removing the toxic organic matters is finally achieved. The harmless organic matters are called as co-metabolism carbon sources, which not only can solve the problem that organic carbon sources are insufficient when the toxic organic matters are degraded by microorganisms, but also can improve the tolerance of the microorganisms to the toxic organic matters, improve the stability of a treatment system and finally achieve the effect of efficiently removing target pollutants. However, the traditional acclimatization method based on the co-metabolism technology mainly selects glucose, starch, sodium acetate and the like to artificially synthesize carbon sources, so that the investment is huge, and huge burden is brought to the treatment of the phenol-containing wastewater. The domestic sewage contains abundant types of carbon sources, the source is wide, the domestic sewage is used as the carbon source, on one hand, the domestic sewage is consumed, the burden of a water plant is reduced, on the other hand, the carbon source in the domestic sewage can promote the removal rate of the microorganism parachlorophenol, and the co-metabolism degradation efficiency is improved. In addition, in the research of co-metabolism treatment of phenol-containing wastewater, no report of using domestic sewage as a carbon source is seen, so that the method has novelty and originality.
The method takes domestic sewage as a co-metabolism organic carbon source, takes an SBR reactor as a main domestication device, and domesticates the aerobic microorganisms capable of degrading 2,4, 6-trichlorophenol.
Disclosure of Invention
The invention provides a method for domesticating microorganisms capable of co-metabolizing and degrading 2,4, 6-trichlorophenol by taking domestic sewage as a carbon source, aiming at the problem of excessive investment in domesticating microorganisms and operating a degradation device in the traditional co-metabolizing technology.

(1) starting the SBR reactor: taking secondary sedimentation tank sludge from a municipal sewage treatment plant as inoculated sludge, sieving the inoculated sludge, leaching for more than three times, removing impurities, and maintaining the sludge concentration of the SBR reactor between 3000-4000 mg/L;
(2) the runtime adjustment operation is as follows:
the first stage is as follows: in the period of 9-12 days, only introducing domestic sewage into the domestication system to recover the microbial activity; and a second stage: when the domestic sewage is kept to enter water when the domestication in the first stage is finished, 2,4, 6-trichlorophenol is added in a mode that the concentration gradient is sequentially increased, and the domestic sewage is added in a mode that the concentration gradient is gradually increased from low concentration to high concentration, namely, the trichlorophenol concentration in the system is in a range of 10 mg/L-100 mg/L, after each concentration is added, when the effluent water cannot detect the 2,4, 6-trichlorophenol, the inlet water concentration of the 2,4, 6-trichlorophenol is increased until the degradation amount of the chlorophenol by microorganisms reaches the maximum, the domestication in the second stage is finished, and the system enters a stable operation stage;
the drainage ratio of the SBR reactor in the operation process is 70 percent; in the first domestication stage, active sludge is not discharged from the system, sludge discharge is started in the second operation stage, the sludge age (SRT) of the system is maintained for 35-40 days, and the sludge concentration is maintained at 3000-4000 mg/L.
And during the whole domestication period, starting the stirrer to ensure that the interior of the SBR reactor is in a complete mixing state, adjusting the gas flow meter to carry out aeration, and maintaining 5-6 mg/L of dissolved oxygen in the SBR reactor.
The SBR reactor runs for two periods a day, and the Hydraulic Retention Time (HRT) is 20-24 hours.
The invention relates to a method for domesticating microorganisms capable of co-metabolizing and degrading 2,4, 6-trichlorophenol by taking domestic sewage as a carbon source, which has the following characteristics:
(1) domestic sewage is used as a carbon source, and an artificial carbon source is not required to be added, so that the economic burden in the process of co-metabolism and degradation of 2,4, 6-trichlorophenol is reduced.
(2) The carbon sources in the domestic sewage are rich in types, and can more quickly domesticate the microorganisms capable of degrading the 2,4, 6-trichlorophenol than artificially adding a single carbon source.
(3) The microorganism domesticated by the domestic sewage and co-metabolically degrading the 2,4, 6-trichlorophenol can tolerate and degrade the 2,4, 6-trichlorophenol more than 90 mg/L.
