Description

Biological treatment exempt from wash by water public lavatory

Technical field

The utility model is related to a kind of public lavatory, and in particular to a kind of biological treatment excrement exempt from wash by water public lavatory.

Background technology

The improvement of people's living standards, is also embodied in the requirement to public lavatory, and neat and tidy is not required nothing more than and also requires odorless It is tasteless.Traditional settling mode is exactly to increase water consumption, is such as frequently found in lavatory, goes out people from lavatory and rushes a water, toileting person is again Rush the phenomenon of a water.According to averagely draining 5-8 times for each person every day, calculated every time with water 6-12L, it is accomplished by 30 for each person every day- 60L water.The population of official statistics Beijing in 2014 is 21,520,000, and the daily flushing water in light Beijing is accomplished by 650,000 cubes - 129 ten thousand steres of rice.These water are sent to fecal sewage treatment factory, by the process such as removal of impurities, filtering, anaerobism, aerobic, film process Qualified discharge water is processed into, the RMB wasted is a fearful numeral.In order to solve water resource waste problem, from public lavatory Start with, just arisen at the historic moment it is various exempt from public lavatory of washing by water, it is that plastics are packed formula public lavatory and biochemical degradation to exempt from bath public lavatory main Types Formula ecological toilet.Plastics packing formula public lavatory needs a number of packaging material (such as polybag), it is necessary to all clear liquid dung, Whole unpackings are also needed to during processing, so cost is higher, and polybag or hard-degraded substance, bring secondary dirt to environment Dye.In addition in the winter of severe cold, colostomy bag easily freezes, and limits area and the time of application.Biochemical degradation formula ecological toilet is Innoxious, minimizing and recycling treatment are carried out in situ to night soil by the biochemical degradation effect of aerobic microbiological, overcome The defect of packing formula public lavatory.Compound in such as application publication number CN105030129A includes plant ash, deodorant and drier, Organic fertilizer is directly prepared into by the mixing of compound and excrement, then organic fertilizer packed by organic fertilizer automatic packaging device, is gone out What is come is exactly the organic fertilizer that one bag of bag can be used directly.It is well known that containing substantial amounts of bacterium, it is necessary to pass through micro- life in excrement Thing hot fermentation certain time, pathogen therein is killed, and make the organic matter degradation of macromolecular into the humus ability of stabilization Organic fertilizer can be referred to as.This patent uses simple hybrid mode, is not carried out at the innoxious of excrement, minimizing and recycling Reason.Such as application publication number CN104563244A, although using black soldier flies processing, but the collection side for using black soldier flies to climb out of automatically Method, it is well known that black soldier flies are a kind of insects, growth rate can not possibly be the same, and only the ripe insect no longer fed just climbs Go out, so using the collection method climbed out of automatically for delay process method, inefficiency, it is impossible to meet the need of public toilet faeces processing Ask.

Black soldier flies (Hermetia illucens L.), originate in America, widely distributed in the whole world at present, belong to S Stratiomyidae insect, can take food fowl and animal excrement and house refuse, the animal protein feed of high value be produced, because its breeding is fast Speed, biomass is big, and feeding habits are extensive, sorption enhanced rate is high, easily management, so as to carry out recycling, its larva is referred to as " phoenix Phoenix worm ".
