Abstract

The present invention includes increases intermediate water producing factory, intermediate water supplying pipeline and domestic waste water recovering pipeline on the basis of available water supply pipeline; re-constructing city excrement draining and recovering pipeline and re-builds the city sewage processing factory into organic fertilizer plant. The city domestic sewage is drained in new pipeline for recovery and processing into intermediate water for secondary use in flushing toilet and other proper purpose. The city excrement is recovered and treated to produce marsh gas and organic fertilizer.

Description

Urban water conservation subitem water supply and draining and urban night soil handle and fertilizer utilizes system again

Affiliated technical field

The present invention relates to a kind of supply and discharging of city domestic water, especially can finish the subitem supply and the discharging of drinking water and undrinkable water, make daily life sewage obtain second use, reach confession, drainage system that water saving purpose and fertilizer utilize again.

Background technology

The supply of urban water use at present is to have continued to use drinking water and undrinkable water for many years to merge supply, the method for disposable discharging always.The result who brings thus is that daily life sewage is closing fecal sewage and discharging together, causes a large amount of daily life sewages to run off in vain, is the waste of water resource, has increased pressure to municipal sewage treatment again; There is urban population more than 300,000,000 in China, moving mouthful of 100,000,000 multithread, and every day, a large amount of ight soil caused great pressure to municipal sewage treatment.And the vast rural area of China is faced with the fertilizer famine again, entirely by using a large amount of chemical fertilizer to keep output.The unicity of fertilizer use had both increased the cost of production of agricultural product, gave the sustainable development of agricultural production again, had stayed potential harm.The ight soil of a large amount of populations in city is not used, and also is the great wasting of resources, has strengthened the fund input that sewage clarification is handled again.

Summary of the invention

Existing can not to reach drinking water and the supply of undrinkable water subitem in order overcoming, to cause the deficiencies of water, a large amount of wastes of fertile resource, the invention provides a kind of confession, drainage system for, drainage system.This system can not only realize saving the purpose of a large amount of living water uses, can also realize the fertilizer recycling, and need not too big fund input.

The technical solution adopted for the present invention to solve the technical problems is:

This system is handled by water supply, draining and urban night soil and fertilizer utilizes three parts to form again.

A: water supply part

1, it is constant to keep existing public supply mains; Keep existing water supply network toward the kitchen of resident living area, the water supply line of wash basin, washing machine, bathtub is constant.

2, one or several of the newly-built or reconstruction scale does not wait the middle water factory by city size.

3, set up the therefrom past resident living area of water factory, urban restroom, the industry that is suitable for middle water, middle water water supply network one cover of enterprise.

4, set up pipeline one cover of washing by water toward the pipeline and the past urban restroom of the bath of washroom urinal in the resident family, and it is connected with middle water water supply network.

B: water discharging part

1, it is constant to keep existing drainage pipeline networks, transforms it into public lavatory and family's urinal draining pipe special, with ight soil and the sewage transport organic fertilizer manufactory to new reconstruction.

2, set up the pipeline of equipment drainings such as being used for connecting kitchen, wash basin, washing machine, bathtub and flooring outfall and pipe network one covers of straight-through water factory.

3, the draining of the natural rainwater of draining and city of equipment such as residential kitchen, wash basin, washing machine, bathtub is separated water factory during the natural rainwater of daily life sewage and city is transported in the lump from original drainage pipeline networks.

C: urban night soil is handled and fertilizer utilizes part again

1, will have the organic fertilizer factory that Wastewater Treatment Plant's reconstruction does not wait for scale now.

2, the ight soil that will come from resident living area make detoxification, the processing of anhydrating.

3, utilize dwell phase in the ight soil processing procedure, produce biogas.Utilize the mode of biogas, can establish line transportation or make the inner wrapping transportation.

4, will make variable concentrations through the muck of the detoxification that anhydrates, that suitable different crops is used, transportable barreled, packed finished product fertilizer.

5, set up the fertilizer sales network, fertilizer is sold to pollution-free food production base and large tracts of land soil compaction, the arable land soil property is badly in need of the area of optimization.

The beneficial effect of this invention is, can realize the second use to daily life sewage by implementing the subtube supply and the discharging of drinking water and undrinkable water, makes its function of undertaking undrinkable water, thereby accomplishes a water dual-purpose, reaches the purpose of water saving.In people's living water use, the frequency of flushing toilet bowl is the highest, and water supply volume is also maximum.Carry out subitem and supply water, the water-saving amount of water reuse can be alleviated the contradiction of China's town and country serious water shortage to greatest extent.Owing in the daily life sewage of water factory, picked out original ight soil in being transported to, the purification difficulty of sewage descended significantly.And return the middle water of supplying with the residential block, be only to be that the undrinkable water of flushing toilet bowl special use, the production of middle water and use cost can reduce significantly; The utilization again of the harmless treatment of ight soil and fertilizer is the production and the development of pollution-free food, is the optimization of the large-area arable soil organic matter of China, and the supply and demand resource of organic fertilizer is provided.Both can adjust existing fertilizer utilization structure again, increase the organic matter of soil, recover the natural soil fertility in arable land, optimize farmland quality comprehensively, and promote China's agricultural production to realize stable high yield for beautifying urban environment eases off the pressure.The pipeline of the recovery of daily life sewage and middle water supply all only need be lower than the common pipe of existing tap water hygienic requirements, and fund input does not need very big.

Description of drawings

Below in conjunction with drawings and Examples this invention is further specified.

Accompanying drawing is water of the present invention, fertile flow graph.

Among the figure: 1, water works, 2, middle water factory, 3, resident living area, 3-1, kitchen, 3-2, bathtub, 3-3, wash basin, 3-4, washing machine, 3-5, family expenses urinal, 4, urban restroom, 5, use in industry, the enterprise of water, 6, organic fertilizer manufactory, 7, fertilizer producing plant detoxification workshop, 8, fertilizer producing plant biogas production workshop, 9, fertilizer producing plant composting workshop, 10, fertilizer producing plant fertilizer sales department, 11, pollution-free food production base and arable land large tracts of land lack the area of organic fertilizer, and 12, the natural rainwater in city.

The specific embodiment
