Rinse-free closestool for separating excrement from urine and respectively recycling excrement and urine

Abstract

The invention discloses a rinse-free closestool for separating excrement from urine and respectively recycling excrement and urine. The rinse-free closestool comprises a seat shell (1) and a seat shell cover (2) and is characterized in that a bottom opening of the seat shell (1) is connected to an excrement and urine separator (3) which is connected to a urine treating tank (5) through a urine collection pipeline (4), an excrement fermentation treating box (6) is connected to the rear part of the excrement and urine separator (3), a gas purification box (7) is connected to the upper part of the excrement and urine separator (3) so that the excrement and the urine are separated and utilized after being treated. The closestool has the advantages that: the aims of water saving, energy saving, no pollution, less investment and certain social benefits can be realized as the rinse is free, the excrement and the urine are respectively treated by adopting a fermented and non-polluted way and respectively utilized, and treating devices are not added; meanwhile, the treated excrement materials are directly prepared into fertilizers, and a part of cost can be reclaimed, therefore, the community benefits are increased; and the use is convenient as microcomputer program control is adopted. The invention can be widely used in community-based residential buildings.

Description

technical field [0001] The invention relates to an improvement of a toilet, in particular to a water-free flushing toilet which can not only save water, but also automatically separate stool and urine for separate treatment and utilization with less investment. The toilet is especially suitable for residential buildings in small communities. Background technique [0002] At present, the toilet used in the community residential building comprises a funnel-shaped seat shell, a water tank, a float valve, a water seal elbow, a water inlet pipe, a sewer pipe, and a septic tank. The water tank is arranged at the rear of the funnel-shaped seat shell. And it is made as a whole with the funnel-shaped seat shell, and a floating ball valve is installed in the water tank, and the water tank is connected with the water inlet pipe. After flushing with water, there is always a certain amount of water in the bent neck of the water seal, which acts as a water seal and prevents the odor from...

Problems solved by technology

Although this toilet has been in use for many years, it also has the following obvious shortcomings: the one is that the waste of water is large, because no matter it is defecation or urination, it must be flushed with water in time after defecating, and every flush is a tank of water. The amount of water used to flush toilets per person per day is more than 15-20 kg. Obviously, the amount of waste of this water is quite astonishing. Combined with the shortage of water resources in our country, it is very meaningful to save this part of water; The second is that urine enters the septic tank or enters the urban pipe network, which not only causes environmental pollution, but also greatly increases the discharge of urban sewage, which wastes both resources and energy; the third is the investment in the entire system Large and difficult to manage, especially when the pipeline is blocked or the septic tank pipeline is not smooth, it will cause feces to overflow and management is troublesome

The water-free biological treatment fertilizer type is installed with a compost fermentation processor, the feces enter the fermentation tank after passing through the toilet, and are degraded by microorganisms. After fermentation, they are sterilized at high temperature, sterilized, dried and packaged as The disadvantages of organic fertilizers are: because the stool and urine are not separated, the fermentation often fails; the toilet is not clean, the smell is strong, and it is not suitable for indoor use; the investment in equipment is still large

The circulating water flushing type is to reuse the water obtained after the urine is processed. Its disadvantage is that it can only save water, but cannot solve the problem of water waste, and the treatment system is huge.

At present, there is no report on the use of ecological principles to make household water-free toilets in community-oriented residential buildings
