Description

Multi-source organic waste material cooperative conversion sewage treatment composite carbon source system Technical Field The application relates to the technical field of multi-source organic waste treatment, in particular to a multi-source organic waste cooperative conversion sewage treatment composite carbon source system. Background The high efficiency of the denitrification process in the current sewage treatment is increasingly important. The denitrifying microorganisms require sufficient and balanced nutrients when performing denitrification, and a carbon source is one of the key factors. The proper carbon source can provide sufficient nutrition for denitrifying microorganisms and promote the growth and metabolism of the denitrifying microorganisms, so that the denitrification efficiency is effectively improved. However, conventional additional carbon sources such as methanol, sodium acetate, glucose, etc. are costly, and it is difficult for a single carbon source to meet the overall demands of denitrifying microorganisms for multiple nutrients. Meanwhile, a large amount of organic waste such as three-phase centrifugal waste liquid generated in the kitchen waste aerobic fertilizer preparation process, waste pulp generated in the orange peel production and processing process, biodiesel production byproducts, polysaccharide byproducts generated in the traditional Chinese medicine production and processing process and the like are not effectively utilized, so that not only is the resource wasted, but also the problem of environmental pollution is caused. If the organic waste materials can be converted into the composite carbon source for sewage treatment, the environmental problem can be solved, the sewage treatment cost can be reduced, and the method has remarkable economic and environmental benefits. In the aspect of organic waste treatment, the existing treatment modes of organic waste such as alcohol byproducts of biodiesel prepared from kitchen waste, dried orange peel waste pulp and kitchen waste oil and polysaccharide byproducts of alcohol extraction processes of traditional Chinese medicine factories have a plurality of defects. The three-phase centrifugal waste liquid generated in the process of the kitchen waste aerobic fertilizer preparation technology is directly used as high-concentration organic waste water for purification treatment, the sewage treatment technology is complex, the engineering cost is high, the operation cost is high, and the profit level of kitchen waste treatment projects is seriously influenced. Most of the dried orange peel waste pulp is directly discarded, so that resource waste is caused, and meanwhile, the problems of peculiar smell and environmental pollution can be caused by decay and decomposition in the natural environment. Crude glycerol, because of the high impurity content, is limited in its subsequent use and generally requires a complex and costly refining process to be used in other industrial fields. The byproduct of the alcohol extraction of polysaccharide from traditional Chinese medicine is usually treated as waste, and is not effectively utilized, and rich nutrients contained in the byproduct are wasted. Therefore, in view of the above problems associated with conventional carbon source applications and organic waste treatment, it is highly desirable to develop a system that can effectively utilize organic waste and provide a high quality composite carbon source for denitrification in wastewater treatment. Disclosure of utility model The application aims to provide a multi-source organic waste cooperative conversion sewage treatment composite carbon source system so as to solve the problems of the traditional carbon source application and organic waste treatment, so that various organic wastes can be converted into a composite carbon source, the recycling of the organic wastes is realized, the sewage treatment cost is reduced, the denitrification efficiency is improved, and the urgent requirements of the sewage treatment industry on high-efficiency and low-cost carbon sources can be further met. The application provides a multi-source organic waste cooperative conversion sewage treatment composite carbon source system, which adopts the following technical scheme: The multi-source organic waste material cooperative conversion sewage treatment composite carbon source system comprises; The device comprises a kitchen waste pretreatment device, a waste pulp pretreatment device, an alcohol byproduct pretreatment device, a polysaccharide byproduct pretreatment device, a stirring sterilization treatment device and a collection and storage device; The kitchen waste pretreatment device, the waste pulp pretreatment device, the alcohol byproduct pretreatment device and the polysaccharide byproduct pretreatment device are respectively matched with the stirring sterilization treatment device so as to respectively add pretreated kitchen waste three-phase centrifuge
