Description
Technical Field
The invention relates to the technical field of standard-reaching emission of public toilet excrement, in particular to a standard-reaching micro-emission treatment system for urban public toilet excrement and an application method thereof.
Background
The excrement treatment process of various mobile public toilets currently in use mainly comprises the following two process routes: firstly, an AO process system based on microbial fermentation is adopted; and secondly, a collection transport vehicle is adopted to carry out door-to-door collection every day and transport the collected materials to a centralized processing point for centralized and unified processing.
Specific disadvantages for the first treatment route are as follows: the AO pool has a large volume, and the required pool volume for the treatment capacity of excrement in 100 people per day toilets exceeds 2m3(ii) a The treated sewage needs to enter a municipal sewage pipe network for retreatment, namely a sewer is needed; tap water for washing hands and washing a toilet is needed; because the pond holds great, and weight is heavier, and the inner space of the public latrine building that occupies is also great, generally places in the bottom of building, just so brings two kinds of different selections for public latrine building structure: or raise the ground terrain clearance of public latrine, or dig a pit on the ground, if adopt and raise public latrine ground terrain clearance's building structure mode, then must correspond longer slope and the step stair of advancing of building, this has brought two unfavorable places: a. the floor space of the building is increased; b. the inconvenience is brought to the disabled, the humanistic care is lack, if the purpose of reducing the ground clearance of a public toilet is achieved by adopting a foundation to dig a pit and install an AO pool, the other two disadvantages are brought: firstly, the mobility of the public toilet is basically not available; secondly, many places do not allow to destroy the ground, thus greatly limiting the application range. For example, the ground is generally not allowed to be damaged on each main road of a city, and the two sides of the road of the city are just the places needing the most mobile toilets.
Specific disadvantages for the second process route are as follows: tap water for washing hands and washing toilets; every public latrine must set up the dirty storage jar of excrement of reasonable volume, and in order to facilitate the collection, the storage jar must be placed in the bottom of lavatory building, and this can bring two adverse effects: the toilet does not occupy the effective use space of the toilet and does not raise the ground height; the greatest disadvantage is the high frequency of upper door collection transport: if the number of public toilets is large, the management difficulty and the workload are large, and the road traffic of urban excrement transportation is a great difficulty.
At present, urban public toilets have the defects of large occupied area, low use coverage, low humanistic concern degree, high management, operation and maintenance difficulty, high difficulty in cleaning and transporting liquid hydraulic excrement, incapability of recycling resources and the like, and therefore, the urban public toilet excrement standard-reaching micro-discharge treatment system and the use method thereof are provided.

step six: the air inlet of the odor treatment module is communicated with the air outlet of the fecal sewage dehydration, fermentation decrement, sewage purification and carbonization incineration module, and the odor produced in the working process of each relevant module is concentrated into the odor treatment module, oxidized and degraded to reach the standard and then discharged to the external environment;
step seven: the air outlet of the fresh air water production module is communicated with the inside of the toilet, fresh air generated by the module is purified, disinfected and temperature-regulated to air in the toilet, the water outlet of the module is connected with a water tap of a hand basin, and air condensate water generated by the fresh air water production module is collected, stored, disinfected and purified and then used for washing hands.
