The invention provides an optimized treatment method for urban night soil and garbage, which comprises the following steps of: storing and fermenting night soil by using a flushing-free odorless fertilizer-collecting toilet; burning organic waste and straw particles into ash by using a straw coking and reburning high-efficiency environment-friendly furnace; mixing organic ash with the fermented night soil to be moderate wettability, filling the mixture into bags as fertilizer, or directly filling the straw particles and part of organic waste which is easily rotten into the toilet and fermenting with the night soil to form fertilizer; and collecting and transporting; after the fertilizer is used in the country, recovering and cleaning the bags and filling the straw particles into the bags and returning to a city. By adopting the scheme, the toilet is flushed without using water, so that water resources are saved; the night soil and the garbage cannot flow out of residents along with waste water, so that the pollution to the environment is avoided; heat energy at a hearth port of a burning furnace is available, and thus energy saving is realized; and the fermented night soil is mixed with ash to form the fertilizer, so that economic expenditure of chemical fertilizer is saved and the pollution from the chemical fertilizer is avoided. The technology is a feasible technology with the advantages of environment friendliness, energy saving and function of changing waste into useable materials.
Description
technical field [0001] The invention relates to an optimized treatment technology for urban excrement and garbage, in particular to a feasible method for converting urban excrement and garbage into farmland organic fertilizer, and belongs to the technical field of excrement and garbage treatment. Background technique [0002] Usually, in large and medium cities, people's feces are flushed into septic tanks by pipes, and finally discharged into sewers and flow into rivers. Based on the calculation of a city with a population of 1 million, each person discharges 1 catty of feces per day, a total of 500 tons, plus ten times the water for washing, and discharges 5,000 tons of sewage every day, which is an astonishingly large amount. In addition, garbage sorting and recycling is a big problem, and the current garbage disposal is not satisfactory. In recent years, the environmental protection department has achieved good results in the treatment of factory sewage, but has not mad...
