In the invention, the steps are fewer, the processing time is short, subsequent process is not needed basically, the mobile toilets can be used and cleaned at any time, so that the method is suitable for processing excrement in mobile toilets on trains or passenger ships and temporary toilets, and is a excrement processing mode with ecological water saving property.
Description
[technical field]
The present invention relates to the human faecal mass purifying treatment method, relate in particular to and a kind ofly be suitable for Porta Pottis such as train, boats and ships, and the fecal sewage purifying treatment method in provisional lavatory.
[background technology]
The present handler's ight soil of China adopts biological treatment substantially, utilizes the principle of precipitation and anaerobically fermenting, makes the organism in the ight soil resolve into stable inorganics, and putrefactive raw sludge is converted into stable ripe sludge.Regularly mud is drawn outward transport clearly, landfill or as fertilizer.Treatment time generally needs 3 months.For the ight soil of Porta Pottis such as train, boats and ships, major part is directly to shed in railway both sides or river, the lake water.In recent years, the train manure contamination obtains the great attention of State Environmental Protection Administration, and the Ministry of Railways also addresses this problem at positive tissue.The way that has adopted at present is to increase acquisition system onboard to collect excrement sewage, and pump drainage focuses on behind the station.Because economy, technology and people's problems such as quality, this train sealed-type toilet only uses on EMUs and part direct train at present.The research that relevant dejection and sewage of train is handled is many is treatment process after collecting, some schools and research institution have also proposed the scheme of directly handling ON TRAINS, what have has also applied for patent, these schemes or can not handle fully, perhaps can not (have only the only about half of time travelling in true train running environment (vibrations at a high speed,, outside wide temperature range) and operation scheme, do not have electricity, gas, water during parking in the railway carriage) under, realization purifies and fails to put into practice in the available finite space of train.
[summary of the invention]
It is short that the technical problem to be solved in the present invention provides a kind of treatment time, the instant clear Porta Pottis such as train, boats and ships and the fecal sewage purifying treatment method in provisional lavatory of being suitable for.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is the ight soil of Porta Potti to be taked treatment steps such as secondary solid-liquid separation, biological degradation and chemical purification, and the degradation bacterial agent in the biological base was degraded isolated solids in 5 hours fully; Special-purpose scavenging agent is muddy sewage purification, after further sterilization, decolouring and deodorizing, become up to standard in water directly in the Porta Potti reuse, specifically may further comprise the steps successively:
(1) solid-liquid separation: use the flushing with clean water urinal at every turn after an action of the bowels, will send into solid-liquid separator towards mixture after an action of the bowels and carry out solid-liquid separation, obtain liquid A and solids B after the separation; Liquid A is sent to ozonation aerated chamber, and solids B is sent to the biological degradation case;
(2) biological degradation: the indoor biological base that fills of biological degradation, solids B and biological base are stirred, the degradation bacterial agent in the biological base was degraded solids B in 5 hours fully; The H that degraded produces
2O, CO
2, NH
3Enter atmosphere Deng gas;
(3) dosing purifies: handle through adding the special purification agent, the dirt in the sewage is flocculated into alumen ustum shape solids;
(4) secondary solid-liquid separation: alumen ustum shape solids is carried out solid-liquid separation, obtain liquid C after the separation;
(5) sterilization, decolouring, deodorizing: with the water purification D of liquid C, D is sent to water tank, is used to wash the lavatory through water water quality standard in must reaching after the processing of disinfection rod, filter stick and absorption rod.
As preferably, also comprise ozonation aerated pre-treatment, the liquid A that step (1) obtains is passed through ozonation aerated processing 1-3 minute, be sent to step (3) dosing purifying treatment then.
As preferably, the described degradation bacterial agent of step (2) is the biological inoculum through the domestication.
As preferably, the described special purification agent of step (3) has excrement sewage purification and flocculation dual function.
The invention has the beneficial effects as follows, method by comprehensive use physics, biological and chemical is handled ight soil and sewage that Porta Potti produces, wherein solids can be decomposed fully, sewage disposal Cheng Zhongshui can be directly used in the Water flushing for cistern in lavatory, its treatment step is few and the treatment time short, at any time use clearly at any time, the ight soil that is suitable for Porta Potti on train or the passenger steamer and interim lavatory is handled, and is a kind of ight soil processing mode of ecological water saving.
[description of drawings]
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Fig. 1 is the step skeleton diagram of Porta Potti ight soil purifying treatment method embodiment 1 of the present invention.
Fig. 2 is the step skeleton diagram of Porta Potti ight soil purifying treatment method embodiment 2 of the present invention.
[embodiment]
Embodiment 1:
Fig. 1 has represented a kind of Porta Potti ight soil purifying treatment method, and step is as follows:
(1) solid-liquid separation: use the flushing with clean water urinal at every turn after an action of the bowels, will send into solid-liquid separator towards mixture after an action of the bowels and carry out solid-liquid separation, obtain liquid A and solids B after the separation; Liquid A is sent to ozonation aerated chamber, and solids B is sent to the biological degradation case;
(2) biological degradation: the indoor biological base that fills of biological degradation, solids B and biological base are stirred, the degradation bacterial agent in the biological base is through the bacterial classification of domestication, can in 5 hours solids B be degraded fully; The gas that degraded produces enters atmosphere;
(3) dosing purifies: directly be spilled into the special purification agent with throwing out in the sewage that step (1) obtains, stirred 2-3 minute under the 200-300ppm rotating speed, form clear water and alumen ustum shape solids;
(4) secondary solid-liquid separation: will handle the alumen ustum shape solids that obtains through step (3), and carry out solid-liquid separation once more, isolated solid part is sent to the biological degradation chamber; The liquid that separation is obtained is sent to next step, and the solids maximum length after secondary separation in the liquid is less than 0.2mm;
(5) sterilization, decolouring, deodorizing: the water purification with water water quality standard in must reaching after the processing of the isolated liquid of step (4) through uv sterilisation rod, PP filter stick and charcoal absorption rod, water purification is sent to water tank, be used to wash the lavatory.
The used biological degradation of present embodiment chamber has heating and heat insulation function, and guaranteeing does not have under the situation of power supply the dirt of not degraded to be degraded fully at train stagnation of movement warehousing.
