Description
Technical field
The invention belongs to field of sanitary equipment, specifically, the present invention relates to the application of one way of life sewage disposal device, wherein said domestic sewage treatment device is the night soil treatment equipment for ecological flush-free toilet, especially be applicable to being applied to ecological flush-free toilet, the sanitary sewages such as urine are separated with solids such as ight soil, process respectively.
Background technology
Existing flush-free toilet mainly contains two kinds of forms: baling type water-avoiding closet and ecological flush-free toilet.Baling type water-avoiding closet needs to expend wrapping material (as plastics bag), not only has higher use cost, clears cost, and due to the refractory organics of plastics, more brings secondary pollution; In addition, in severe cold weather, colostomy bag easily freezes, and low temperature adaptability is poor, limits applicable area.
And ecological flush-free toilet is, by the biochemical degradation effect of aerobic microbiological, human excrement is carried out resource utilization, innoxious and minimizing process on the spot, overcome the defect of baling type water-avoiding closet.Had at present much configure difference, the ecological flush-free toilet of configurations come out, such as, Chinese patent CN1189253C and the disclosed ecological flush-free toilet such as Chinese patent or patent application CN1773034A, CN2761126Y, except being placed in fixed-site, they also can be widely applied to the mobile place such as train, automobile (e.g., can see Chinese patent CN2803845Y, CN2801575Y, CN2838507Y).But, fermenting container in night soil treatment equipment (being also sometimes referred to as biochemical reactor, main frame etc. in the prior art) in these existing ecological flush-free toilets is directly communicated with bottom squatting wc pan, and toileting person is easy to directly see and likely touches the internal unit such as fecaluria degradation product and agitator that fermenting container internal mix has microbiobacterial agent.Although substantially improve smell under the effect of microbiobacterial agent, this also gives on toileting person visual perception and brings uncomfortable sensation; Secondly, after having toileting person to enter lavatory, when shifting board is opened, for the sake of security, generally agitator will be closed, if the frequency that goes to toilet is high, closing and be unfavorable for very much fecaluria and microbiobacterial agent mixing and ventilate in long-term pass, affects the degradation efficiency of microorganism to fecaluria; In addition, especially children stretch into fermenting container inside sometimes out of curiosity and by hand, even and if the more sharp-pointed agitator in edge also causes danger than being easier to when shutting down.For this reason, No. 200710143603rd, Chinese patent application and PCT application PCT/CN2007/002591 disclose a kind of night soil treatment equipment for ecological flush-free toilet, and what which increase the temporary transient manure buffer that temporarily can store fecaluria when going to toilet and do not have a palp sharp edges scrapes device.
But, only establish a hole (or being called hole) bottom the squatting wc pan in the ecological flush-free toilet of these existing routines, regardless of urine with faecal solids is all direct enters night soil treatment equipment from this hole, there is no excrement and urinate the function be separated.And, because the water content difference of ight soil and urine is very large, night soil treatment equipment of the prior art (is also sometimes referred to as biochemical reactor in the prior art, main frame etc.) in microbiobacterial agent (can see such as, Chinese patent CN1189253C, Chinese patent application CN1916163A and No. 200710142813.4th, the Chinese patent application submitted on July 30th, 2007, No. PCT/CN2007/002591st, the PCT patent application on August 28th, 2007 submits to) usually need to compare dry environment to ferment, make ight soil decrement, therefore when urine is many time, the well heater in night soil treatment equipment is just needed constantly to work to keep dry, need to consume a large amount of electric energy.
Although No. 200710165478.Xth, Chinese patent application and No. 200720195828.2 devise a kind of squatting wc pan for ecological flush-free toilet newly, which increase logical urine hole and prominence, make when normally using, the urine that man toilet user discharges can be collected into storage by logical urine hole and urinate in container, and does not directly enter and be equipped with in the night soil treatment equipment of microbiobacterial agent.But this squatting wc pan can only prevent from the urine of male toilet user from directly entering being equipped with in the night soil treatment equipment of microbiobacterial agent, the urine of all toilet users cannot be made can be collected in storage urine container; And, in with water cleaning squatting wc pan, when especially cleaning around defaecation hole, still inevitable water for cleaning directly enters night soil treatment equipment, thus have impact on the fermentative processing efficiency of wherein microorganism or pay too much electric energy heating evaporation and fall these water.
In order to overcome the defect of prior art, meet the needs of current energy-saving and emission-reduction, the present inventor passes through painstaking efforts, on the basis of the disclosed night soil treatment equipment such as No. 200710143603rd, Chinese patent application and PCT application PCT/CN2007/002591, devise an equipment for separating liquid from solid, not only can solve the problem of the solid-liquid separation such as fecaluria inexpensively, and through the experiment to a large amount of crowd's fecaluria, optimize the position of its mesopore and the diameter in hole, faecal solids is made to be not easy plugging hole, also be not easy to enter storage urine container, thus can use stably in a long term.Such design also brings a unexpected advantage, and namely when staff's use water daily cleaning squatting wc pan or lavatory, without the need to worrying that too much water for cleaning directly enters night soil treatment equipment, more convenient corresponding lavatory is clean thus.
