Technical Field
The invention relates to the technical field of sewage treatment, in particular to a method for using wine-making wastewater for carbon source supplement of a sewage treatment plant.
Background
At present, the requirement on the effluent quality index of a sewage treatment plant is increasingly strict, but in most cases, the composition of substances including but not limited to town sewage relatively lacks a carbon source and is not beneficial to nitrogen and phosphorus removal of a general sewage treatment system, so a carbon source substance supplementing and adding mode is often adopted to increase the nitrogen and phosphorus removal effect of the sewage treatment system, and the existing carbon source substances generally comprise micromolecular organic matters such as methanol, ethanol, sodium acetate, glucose and the like. The addition of these carbon source substances often increases the operating cost of sewage treatment plants and strives for industrial raw material resources. The brewing wastewater is generally a residue leachate, a pit mud leachate, a distillation waste liquid generated by brewing fermentation, wastewater generated by container cleaning and the like, has high concentration and high treatment cost, but also contains a large amount of small molecular organic matters such as alcohols, volatile fatty acids, saccharides and the like, and is a substance suitable for carbon source supplement in a municipal sewage treatment plant. If the brewing wastewater can be partially used for supplementing the carbon source for the urban sewage treatment plant, the operation cost of the sewage treatment plant can be reduced, the sewage treatment pressure and cost of brewing enterprises can be reduced, and the competition of industrial raw material resources in the sewage treatment industry can be avoided. However, the brewing wastewater contains a large amount of macromolecular organic matters and gas-producing microorganisms in addition to the small molecular organic matters, and if the brewing wastewater is directly used for carbon source supplement of urban sewage treatment plants, the organic load of the wastewater is obviously increased, so that the debugging difficulty and the operation cost are increased, and the wastewater is inconvenient to transport due to gas production of microorganisms.
