In practical application, the ecological toilet can be lifted to the concept of the ecological courtyard, organic wastewater such as hand washing water, bath water, laundry water and the like can be collected and treated, the collected organic wastewater also enters the plant filter tank, the plant filter tank is separated by the partition plate, and the collected organic wastewater and toilet flushing water are respectively treated and then flow to the purified water collecting tank for recycling, so that the ecological toilet also has a good application prospect. During the design, according to the application scene specifically, can all bury ground installation with storage excrement jar, plant filtering pond, purification water hold up tank, can play effectual frostproofing effect. The collection and utilization of the excrement and urine in the ecological toilet are both based on engineering practice, the excrement can be used as a raw material for biogas engineering to be fermented, and biogas residues which are one of engineering products can be reused, so that the advantage of maximizing the utilization of excrement resources is obtained.

The working principle of the ecological toilet is as follows:

when a person goes to toilet, firstly, the toilet lid 19 is opened, the person can sit on the toilet main body 2 conveniently, the excrement falls on the first receiving plate 9, and the urine flows into the urine guide groove 14 arranged at the front end along the inner wall surface of the front half part of the toilet main body 2 and flows to the urine storage barrel 18 through the liquid guide system. When the toilet cover 19 is opened, the axial flow exhaust fan 4 is powered on and started, odor is generated more when people are convenient, and a negative pressure area is quickly formed in the air seal ring 11 under the double effects of the exhaust fan 4 and a chimney effect, so that the odor enters the air seal ring 11 from gaps between the first-stage bearing plate 9 and the feces dropping port and the urine guide grooves on the two sides and is then discharged outdoors. Forced exhaust when like the lavatory makes the foul smell can not lose the lavatory room space completely, very big assurance like the lavatory experience. After like the lavatory, click control button 12 on the ecological lavatory control panel and wash the operation, control button 12 presses the back, and control system receives control signal, and then controls each part and realizes follow-up action:

on the one hand, the control system controls the first motor 6 to drive the first screw rod 7 to rotate forwards, so that the first stage bearing plate 9 moves backwards, in the moving process, the first scraper on the first stage bearing plate 9 scrapes excrement on the first stage bearing plate 9 to the second bearing plate 10, and then the first motor 6 rotates backwards to drive the first screw rod to reset the first stage bearing plate 9.

On the other hand, the control system controls the submersible pump in the water storage tank 1 to be started, water stored in the water storage tank 1 flows to the first receiving plate 9 through a water spraying opening of the toilet, so that residual excrement particles on the first receiving plate 9 are washed, the washed waste water flows into the urine guide groove 14 and reaches the liquid flow direction control valve 30 through the liquid guide pipe 15, the liquid flow direction control valve 30 is adjusted to be communicated with the second flow guide pipe 23 under the control of the control system, therefore, the washed washing water flows into the second flow guide pipe 23 through the liquid flow direction control valve 30 and then enters the plant filter 20, the control system controls the submersible pump to stop running according to set time, and then the control system controls the liquid flow direction control valve 30 to be communicated with the first flow guide pipe 16 so that fluid can flow to the urine storage barrel 18. Meanwhile, after the first bearing plate 9 returns, the excrement falls on the second bearing plate 10, at this time, the control system controls the second motor 41 to rotate to drive the second screw rod 42 to move and drive the second bearing plate 10 to move towards the second motor 41, the excrement on the second bearing plate 10 is pushed by the second scraper, along with the movement of the second bearing plate 10, the excrement falls into the excrement storage tank 17 due to the action of gravity, and after the second bearing plate 10 moves to a set position, the second motor 41 rotates reversely to drive the second screw rod 42 to move and drive the second bearing plate 10 to return and seal and cover the excrement falling port 37 on the excrement storage tank 17.

Citric acid can be added into the excrement storage jar 17 through the acid adding port 34, and the excrement can be reduced in fermentation under the action of the citric acid in the excrement storage jar 17, so that the activity of the excrement is maintained, and the subsequent utilization is facilitated. The flushing water flows through the second guide pipe 23 to flow into the bottom of the plant filter 20, sequentially passes through the gravel layer 24, the zeolite layer 25 and the plant layer 26, keeps a certain hydraulic retention time, achieves the aim of flushing water purification, and is discharged to the adjacent purified water storage tank 45 from the water outlet of the third guide pipe 31. The plant filter tank 20 and the purified water storage tank 45 are both buried, so that the freeze protection can be effectively realized, the purified water in the purified water storage tank 45 can be effectively collected and can be secondarily utilized as clean water, the water-saving device has great water-saving significance for areas with relative water shortage, and simultaneously, the water-saving characteristic of the liquid guide switching system suitable for the ecological toilet by the micro-flush is reflected. After the toilet is used for a period of time, excrement and urine in an area are collected by a specially-assigned person in a unified way, the recovered excrement depends on engineering projects, namely the high-quality excrement is used as a fermentation raw material of a biogas project, fermented biogas residues can be used as a fertilizer for secondary utilization, and excrement and sewage resources are utilized for the secondary utilization. Urine is used for extracting phosphorus, nitrogen, urokinase and other scarce nutrient substances.
