Description

A kind of flush-free toilet

Technical field

The utility model belongs to toilet facility and dejecta treatment method field.

Background technology

In general, existing lavatory can be divided into the flush toilet system of (1) access pipe network, and (2) do not access the large class in independent lavatory two of pipe network.

The population in the whole world 60% is used the flush toilet system of access pipe network at present.This individual system comprises uses running water or middle water that the ight soil in toilet seat or squatting pan is poured to sewer pipe, by municipal wastewater pipe network, carries, and finally enters sewage treatment plant and processes.

The problem of flush toilet systems face is: on the one hand, ight soil/urine pollution seldom the wash water of tens times, then and then pollute whole living drainage, make sewage a large amount of, continue to produce; On the other hand, sewage treatment plant, in the face of the sewage of flood tide, can only carry out limited disposal and just must discharge as early as possible, puts the new sewage constantly entering with the capacity place to go of soaring.According to World Health Organization statistics, the sanitary sewage in the whole world 80% does not obtain suitably processing finally discharged to natural waters such as rivers,lakes and seas, causes serious environmental problem and public health hidden danger greatly.

The whole world approximately 40% the population below the poverty line is used the non-bath privy that is not connected to pipe network system, as non-irrigated lavatory, squats over a pit to relieve oneself, and even has quite a few population can only outdoor defecation everywhere without any lavatory.

To these non-bath privies, ight soil urine be stored in such as septic tank one class outdoor, with the place of life water source without good isolation, the diarrhoea class disease causing thus causes about 1,500,000 people dead every year.

As can be seen here, all there is quite serious problem in existing pipe network water flushed toilet and non-pipe network privy, the many innovation teams in the whole world are competitively considering the scheme of " on the spot excreta being carried out to harmless treatment immediately after an action of the bowels ", it is to need a top-priority problem that ight soil urine is dewatered, because: the moisture in slop (ight soil/urine) is greater than 90%, if can dehydrate, need the volume/weight of solid waste to be processed greatly to reduce, make the efficiency of whole processing chain increase cost.Meanwhile, dry ight soil is carried out sterilizing and preserves being easy to many than liquid state.

But, for the aqueous solid that is similar to ight soil class, be dried and be not easy!

In general dry method has two kinds.A kind of is forced evaporation, under normal pressure, ight soil temperature is heated to 100 ℃, with transpiring moisture sterilization, this phase transition process lot of energy, its characterising parameter is gasification latent heat, under an atmospheric pressure (0.1MPa), the latent heat of vaporization of the water in the time of 100 ℃ is 2257.2kJ/kg, specific heat of water holds for 4.2kJ/kg by contrast, and in other words, the energy that moisture gasification consumes is that the identical water yield is elevated to more than 5 times of 100 ℃ of institute's energy requirements from 0 ℃.Therefore because water content in ight soil is very high, conventionally more than 90%, adopt the mode of forced evaporation to process ight soil energy consumption very high.Second method is natural evaporation, also referred to as air-dry, at the temperature of the atmospheric boiling point lower than water (100 ℃), make air flow through ight soil, because the moisture content in ight soil is higher than airborne moisture content, according to diffusion law, the diffusion from concentration eminence to concentration lower of water nature, the moisture in ight soil slowly spreads and is progressively dried in air.

The advantage of forced evaporation is that equipment is simple and rapidly dry, and its shortcoming is that energy consumption is large; The advantage of natural evaporation is: owing to having avoided gasification latent heat, so the energy consumption of dry run is very low, its shortcoming is slow-drying.In addition, natural evaporation can not be killed the microorganism in ight soil, need to add the chemical reagent with microorganism killing effect, but the introducing of this chemical reagent tends to further in ight soil, introduce liquid component, and likely natural environment caused to murder by poisoning.And force drying is if guarantee that 100% ground kills the microorganism in ight soil, needs to extend the heat time, this has further increased energy consumption.

Visible, in the processing procedure of ight soil, in low energy consumption with between being dried rapidly, exist contradiction.And how efficiently and at low cost the microorganism in ight soil is killed on 100% ground, is also a difficult problem.

The water yield that flush toilet consumes after an action of the bowels at least surpasses more than ten times of ight soil urine total moisture content, and it is that be difficult to realize or extremely uneconomic that the fecal sewage that comprises flushing water is carried out to dehydration by evaporation, so must first solve flush-free toilet problem.

In flush toilet system, water has mainly been born three functions, and (1) is rinsed and kept the clean of bedpan, and (2) carry ight soil urine, and (3) absorb stink and isolate sewer odours; Flush-free toilet must be realized above-mentioned three functions by other means.

Therefore, this area needs a kind of flush-free toilet and low energy consumption and rapidly efficient ight soil situ treatment process.Preferably this lavatory and method can also be efficiently and at low cost 100% ground kill the microorganism in ight soil.

Above-mentioned target realizes by apparatus and method of the present utility model.
