Description
Technical Field
The invention relates to end treatment of putrescible matters and kitchen waste in urban life, in particular to an industrial biological treatment process of the putrescible matters and the kitchen waste in the urban life.
Background
In the life of people in cities and towns, rottable matters and kitchen waste become necessary wastes generated in the life process of people, the main components of the wastes are organic matters and inorganic matters adsorbed by zoogles formed by various microorganisms, the quality requirements for treating the rottable matters and the kitchen waste are continuously improved along with the increasing speed of the urbanization process in China, the yield of residual substances serving as byproducts for treating the rottable matters and the kitchen waste is continuously increased, and the treatment and disposal technology of the rottable matters and the kitchen waste faces new challenges.
At present, the disposal approaches of putrescible matters and kitchen waste generally comprise sanitary landfill, incineration treatment, land utilization, microbial treatment and the like. In recent years, the trend of treating putrescible matters and disposing kitchen waste in various countries around the world is to reduce sanitary landfill, moderately develop incineration treatment, and greatly promote land utilization of the putrescible matters and the kitchen waste. However, the incineration cost is high, and statistically, the incineration cost per ton reaches 550-; in addition, incineration also produces CO2 (0.3-0.35 tons of CO2 per ton of sludge incineration) and the highly toxic gas dioxin. On the other hand, due to the factors of huge investment for building incineration plants, potential air pollution and the like, related national regulations stipulate that only one incineration plant can be built in one region, so that the rate of the putrescible and kitchen waste occupied by the national effective treatment is far lower than 30%; the first grade of county and town is nearly untreated, and most of the county and town directly bury the rotten objects and the kitchen garbage. With the rapid increase of urban population, the total generation of national putrescible and kitchen waste is 2 hundred million tons or more in 2015 statistics. (wherein, the kitchen waste is more than 1 hundred million tons) putrescible and kitchen waste and is increased by 5% every year, which brings different degrees of harm to the environment and people's daily life. Particularly, one reason why the spreading speed of the African swine fever which is outbreaked in large area in 2019 in China is that putrescible matters (containing excrement and urine of pigs) and kitchen waste (feeding pigs with hogwash) cannot be effectively treated in a pollution-free manner. Therefore, how to effectively treat the rottable matters and the kitchen waste in a pollution-free and secondary pollution-free environment, prevent the African swine fever from continuously spreading and protect the environment for human survival, and what effective method is adopted to treat the rottable matters and the kitchen waste to achieve zero emission is especially important today in 2019.
The black soldier fly is the best means for treating the rottable matters and the kitchen waste, and the defects exist at present;
firstly, the black soldier fly breeding farm occupies too large area, the rotten garbage is generally concentrated in towns, and due to the rapid development of the town construction, the black soldier fly breeding is not beneficial to the development of the black soldier fly breeding at the edges of the towns under the condition that the land is already expensive like oil. Under normal conditions, 10 tons of putrescible materials are treated one day, a kitchen waste workshop occupies 1400 square meters, and the cost is high due to the fact that tee joints are arranged at one expense in a living area (the living area is equal to 1500 square meters). The 1400 square meters of available empty land is relatively far away from towns, but long-distance transportation is caused, the cost of black soldier fly farmers is increased, and the raising burden is too heavy.
Secondly, regulation, feeding of hermetia illucens and the currently adopted greenhouse cultivation have overlarge areas, and in the remote field, the hermetia illucens need to have the requisite temperature, humidity and air for survival and can prevent the invasion of foreign organisms (birds, hedgehogs, mice and the like, and the statistical amount of adult hermetia illucens eaten in a 10-ton breeding farm every day is about equal to 80-150 kg).
Thirdly, when the hermetia illucens is used for breeding and treating the corrodible garbage in cities and towns, the corrodible garbage is mostly stirred, smashed and directly fed at present, and the method needs a large feeding pond area (at least 1400 square meters is needed for treating 10 tons of the corrodible garbage and kitchen garbage per day). Meanwhile, the output ratio can only reach the efficiency approximately equal to 1/5 and is far lower than the effect of degraded putrescible matter and kitchen waste 1/3, and the occupied area needs to be relatively increased due to the output ratio. Moreover, the putrescible substances are not degraded, the regional space smell of the feeding farm is extremely large, and the relative pollution to the air is caused. Fourthly, the existing method for breeding the hermetia illucens is utilized to eliminate the influence of temperature difference of four seasons on the environment and conditions of putrescible matters and kitchen waste, and the survival adaptive temperature of the hermetia illucens is 20-30 ℃. In China, the temperature difference of south and north regions is huge, most regions are clear in four seasons, the temperature difference is extremely different, the temperature difference fluctuation is small only in a few regions of south provinces, the black soldier fly can be suitable for breeding in four seasons, and the four-season non-dormancy breeding can be carried out, but most of the regions have low temperature (lower than 20 ℃) which is 3-6 months or even longer (the optimal temperature for the black soldier fly to live is 20-30 ℃, and the black soldier fly enters dormancy or death state below the temperature). But the putrescible and the kitchen waste are newly generated every day. When the hermetia illucens enters the low-temperature dormancy at low temperature, rottable garbage can be continuously generated every day, and rottable matters and kitchen garbage can not be treated when the temperature is suitable for the next year. And finally, a large amount of residual substances (the substances which can not be digested by the hermetia illucens) generated in the existing breeding places are directly discarded as wastes, and the discarded substances accumulated in the day and the month (namely the undegradable substances which can not be eaten by the hermetia illucens, including various sodium elements, heavy metals, particulate metals, minerals, mineral product fragments, plastic fragments and the like) can continuously cause secondary pollution to the environment.
