Description
Technical field
The invention belongs to hygienic device, be specifically related to the resource Anhydrous ecological toilet of a provenance divergence type.
Background technology
Anhydrous or the water-saving ecological type lavatory of being popular on market at present can be divided into four classes.1) the circulating water flushing type bio-toilet that urine is processed separately, it is by custom-designed separator, urine to be collected separately, automatically adds special agent to remove after peculiar smell, is back to toilet flushing; After ight soil is dry, can be made into agricultural fertilizer.Its advantage is to make dung recovery, but in use needs a small amount of supplementing water, and daily management requires higher, and the outer National Games of ight soil produce secondary pollution.2) the circulating water flushing type bio-toilet of fecaluria mixed processing, it is to adopt aerobe facture or embrane method etc., utilizes the metabolism of microorganism, dejection degradation is CO the most at last
2and H
2o, the water producing in process is reuse toilet flushing after treatment, also can enter environment.Its advantage is that fecaluria is handled together, and can reuse flush the toilet, but still needs regular moisturizing and regularly remove contamination, and pollutant levels can progressively increase with the operation in lavatory, causes its intractability large, and the cost that moves is for a long time too high, treatment effect is generally undesirable.3) exempt from water microorganism compost type bio-toilet, it can be divided into anaerobic type and aerobic type two classes, adopts anaerobic fermentation or aerobic composting process, and ight soil is finally processed into fertilizer or soil conditioner.Its advantage is without residue, anhydrous, but its deficiency is that the processing time is long, stink is dense, sanitary condition is poor, take up room large.4) exempt from Biodegradation type bio-toilet, as Chinese patent literature CN201409867Y, it adopts the special microorganism fungus kind of cultivating to process ight soil, larger molecular organics is degraded to the small organic molecules such as sugar, aliphatic acid and amino acid, the ight soil minimizing time is short, efficiency is high, and on market, popularization is hotter at present, but this type lavatory is subject to the restriction of fecaluria ratio, as too high in urine ratio, affect growth activity and the efficient degradation of flora; Its bacterial classification need regularly replace in addition and cost is high.
