Description

Novel organic garbage treatment system

Technical Field

The utility model relates to a refuse treatment technical field, in particular to novel organic refuse treatment system.

Background

With the rapid development of urbanization and industrialization in China, the discharge of corresponding pollutants seriously exceeds the standard, so that natural water pollution is serious, a large amount of N, P is discharged into lakes and reservoirs, so that water eutrophication is caused, a large amount of algae grows rapidly, and water sources are seriously polluted. Particularly, the phenomenon of blue algae bloom outbreaked in the Taihu lake since 2007 causes the water supply crisis of the tin-free city, and the problem of lake eutrophication is concerned all over the world. Research shows that over 66% of lakes and reservoirs in China are at the eutrophication level, wherein the eutrophication and the super eutrophication account for 22%, so that the eutrophication becomes a major water environment problem in lakes in China for a long time.

The occurrence of the cyanobacterial bloom is the result of the interaction among various animals and plants in the chemical environment in a very complicated cyanobacterial water body house, and the cyanobacterial bloom is easily formed in summer of the eutrophic water body. Blue algae can release blue algae toxin, and can harm human health through oral ingestion, respiration, skin contact, blood permeation and other ways. The method for treating the generation of the blue algae is a difficult task, at present, domestic methods for removing the algae can be divided into a physical method, a chemical method, a biological method, a comprehensive treatment method and the like, but the blue algae bloom phenomenon can not be radically treated, and some methods even cause secondary pollution of water. In recent years, the water quality and environment of the Taihu lake are obviously improved through blue algae fishing and ecological water regulation, but the treatment of millions of tons of blue algae liquid generated by fishing every year becomes a new environment-friendly task. The two main methods at present are: the method for generating biogas and generating electricity by using the algae liquid recycles the algae liquid, but a large amount of residual liquid cannot be disposed; secondly, the blue algae is dried in a heating and drying mode, and then the algae mud is incinerated, so that the treatment is thorough, but the cost is huge.

In addition, kitchen waste is also a kind of organic waste with a huge production amount. The kitchen waste is mainly classified into food waste and kitchen waste, the food waste refers to food residues of restaurants, unit canteens and the like and processing process wastes of fruits, vegetables, meat, grease, pastries and the like in the kitchen, and the kitchen waste refers to perishable organic waste such as discarded fruits, vegetables, food leftovers, melon and fruit peels and the like in the daily life of a family. The kitchen waste generated in Chinese cities is not less than 6000 million t every year, the kitchen waste yield in large and medium cities is remarkable, and particularly, the problems of developed cities in catering industries such as Shanghai, Beijing, Guangzhou and the like are more serious. Along with the annual increase of the garbage output, the Chinese garbage incineration field increases year by year, and at present, most of the kitchen garbage and the household garbage in China are mixed and stacked, and the traditional incineration and landfill are mainly used. The kitchen waste cannot be recycled by burning and landfill, so that the kitchen waste is greatly wasted, and heavy burden is brought to local finance.

The prior kitchen waste treatment technology has low resource level and is difficult to treat thoroughly. The main treatment technologies of the kitchen waste treatment plant which is put into operation at present are anaerobic digestion, feed additive preparation and industrial oil production, and the residual residue/residual liquid is used for preparing organic fertilizer. Most enterprises have the defects of long process, low treatment efficiency, low technical level, poor working environment, incomplete treatment and the like.

According to the requirements of the implementation scheme of the domestic garbage classification system of the Ministry of development and reform of the state and the Ministry of urban and rural construction of housing, relevant laws and regulations and standard systems for garbage classification are basically established by the end of 2020. The Shanghai leads to the establishment and implementation of the regulations for managing domestic garbage in Shanghai cities in 2019, the garbage is strictly classified and managed from the source, local regulations are already issued in 4 provinces such as Zhejiang, Fujian, Guangdong and Hainan, and 12 local regulations in Hebei and the like enter the legislation program. In 46 major cities, 30 cities have been out of the household garbage classification laws and regulations, and 16 cities have been put into the law plan or have formed a draft for classifying the household garbage. At present, garbage classification depends on administrative means and community propaganda and education guidance, and depends on government management and supervision, so that the whole society makes an effort to classify garbage. Therefore, the quality of the kitchen waste at the source is gradually improved. Therefore, convenient conditions are provided for the resource utilization of the kitchen waste, the reduction treatment and the resource utilization of the kitchen waste are bound to become the hot problems of future domestic research, and novel efficient energy-saving treatment technology and equipment are bound to become the hot points of the direction of technical development and investment.
