Description
Technical field
The utility model relates to excrement and urine treating system, relates in particular to a kind of decontamination of human excreta treatment system.
Background technology
Population increase and high concentration makes the output of urban night soil constantly increase, these ight soil in the past mostly as fertilizer sources directly transport the rural area to, and at present under the impact of the chemical fertilizer that can bring distinct economic, ight soil is in the day by day atrophy of usage quantity in rural area.Thereby adopting suitable technology that ight soil is managed has great meaning to protection of the environment with processing not only, and the health that guarantees the people is also had profound significance.
Excrement and urine water mainly contains suspended particulate (SS) height, ammonia nitrogen (NH
3-the characteristics such as N) concentration is high, organism (COD) concentration is high, the sense organ degree is poor, biodegradability is good.Have for the main treatment technology of excrement and urine water at present: anaerobically fermenting facture, aerobic treatment method, high temperature high pressure process method, septic tank facture, materialization treatment process, During High-Temperature Composting method etc., but the domestic decontamination of human excreta treatment technology that is most widely used in Practical Project mainly is divided into two classes at present:
One class: septic tank is processed: in small and medium-sized cities and the rural area due to the processing of sanitary sewage, collecting dung, to process complete canalization more difficult, the miniaturization manure pit just becomes the most general and the facility that must configuration of apartment.The function of septic tank is to receive, store family domestic sewage.Be divided into floating layer, silt seam and middle clear water layer 3 zone in the pond.Clear water can adopt the mode of sewage irrigation to do final processing.Current the composition of family domestic sewage is increasingly sophisticated due to being widely used of Chemicals, and in sewage, harmful substance contents increases, and the direct discharging of septic tank " clear water layer " just becomes the source of pollution in sewage irrigation zone.Control to this pollution is only to use a large amount of chemicalses to decompose the precipitation objectionable impurities in septic tank, yet in expansion sewage irrigation zone, increasing on the soil treatment function is to be difficult to effectively.Septic tank is processed problems such as going back easy appearance is stopped up, spoil disposal difficulty, processing is thorough, mosquitos and flies grows simultaneously.
Two classes: materialization is processed: be 200710079587x in China Patent No., open day be September 19 in 2007 day, be called a kind of method that disclose materialization processing ight soil in the patent document of " dejecta treatment method and system ".The method is for to carry out solid-liquid separation by solid-liquid separating equipment with ight soil, isolated residue carries out landfill disposal, isolated liquid manure adds appropriate chemical agent, carry out processed by dehydration equipment after making liquid manure generation throwing out, the dried clay as fertilizer sources of the gained that wherein dewaters, liquid are delivered to sewage work and are carried out terminal process.The dejecta treatment method of above pattern has the following disadvantages: for being received of the organic fecal sewage of high density, require the conditions such as designed capacity, operating mode of sewage work to meet to be received the standard of sewage, and fecal sewage to be randomness enter sewage network brings very big inconvenience for the construction plan of sewage work; Fecal sewage is transported in the way of sewage work and can gives out dense stink and be difficult to stink is processed, and is unfavorable for environmental health.
For the above deficiency of the dejecta treatment method that solves above type, designed the liquid dung that produces after dewatering has been further processed to reach after the discharging mark decontamination of human excreta treatment process of discharging again.Number be 2012102516133 in Chinese patent application, open day be October 24 in 2012 day, be called in the patent document of " a kind of decontamination of human excreta recycling processing method " switch a kind of can be with the method for the liquid waste disposal in ight soil to discharging up to standard.The method is for the waste liquid of gained after dewatering gathers chelation treatment successively, the oxygen of holding concurrently is processed and one-level/secondary aerobic treatment arrives laggard row discharging up to standard.The treatment process of the type has the following disadvantages: directly waste liquid is gathered successively chelation treatment, double oxygen processing and one-level/secondary aerobic treatment to laggard row discharging up to standard, the organic substance decomposing that this treatment process causes the nutrient done in liquid dung be for being used as the organism of nutrient, can not realize to the organic abundant recycling in ight soil and nitriding treatment not thoroughly, that COD removes efficient is low; The processed of mud and ight soil is carried out together by same whizzer, be not easy to the reasonable utilization of the nutrient in ight soil, be used because the nutrient of the dried mud of ight soil dehydration gained is high, can be used as fertilizer, and the dried mud of sludge dewatering gained does not almost have any nutrient, is used as fertilizer utilization improper.
