Urban water sources need to be comprehensively considered from the aspects of conserving water sources, utilizing recycled water, intercepting rainwater (sponge cities) and the like. At present, reclaimed water mainly comes from deep treatment water of municipal sewage plants.
(2) Kitchen garbage: the quantity of municipal solid waste is increased rapidly, and the municipal solid waste is divided into four types of kitchen waste, recoverable waste, harmful waste, other waste and the like according to the principle of waste classification. The kitchen garbage is non-recyclable garbage. The disposal mode of kitchen waste is mainly to send the waste to a landfill for landfill, composting and incineration, and the disposal mode becomes an urban problem which needs to be solved urgently.
(3) The demand of organic fertilizer is increased rapidly: along with the construction of national ecological environment, the greening area is larger and larger, so that the using amount of organic fertilizer is increased rapidly, and the environmental problems, raw material problems, energy problems and transportation problems caused by the production and utilization of the organic fertilizer are aggravated.
2. Household garbage processor
At present, the household garbage disposer is a simple crushing technology, and aims to discharge part of kitchen garbage into a city drainage system through an indoor kitchen drainage pipe. After the use, the following main problems exist and are not suitable for wide use: (1) the method increases the operation load and the power load of the municipal sewage plant, improves the sewage treatment cost, (2) causes the problems of blockage of a municipal drainage pipe network, unqualified drainage water quality of the municipal sewage plant, and drastic increase of sludge amount, and the like, (3) the kitchen waste treated by the household garbage disposer has less than 10 percent of the generated amount, and cannot fundamentally solve the problem of disposal of the kitchen waste, (4) most domestic sewage plants basically have no capacity of accepting domestic garbage, (5) increase the water consumption of municipal tap water, and (6) have high price.
