DETAILED DESCRIPTION

[0019] The following is a further non-limiting detailed description of the technical solution of the utility model in conjunction with the preferred embodiments and the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 The utility model provides a technical solution: a mobile toilet with zero discharge for urine, comprising a toilet house 1 and steps 4, the toilet house 1 is hingedly connected to a toilet door 2 on the right side, the toilet door 2 has an inner bearing connected to a door buckle 3, the toilet house 1 is fixedly connected to the steps 4, and two sets of exhaust fans 5 are provided on the upper left side of the toilet house 1, and the two sets of exhaust fans 5 can better discharge the odor in the toilet house 1.

[0021] A urinal 6 is fixedly connected to the bottom of the toilet room 1. A urinal trough is provided in the urinal 6. A urinal hole 61 is provided in the urinal trough. The urinal hole 61 is arranged at the front of the urinal trough. The urinal trough is low in front and high in the back and is in an arc shape, so that the water flow can better flush the urine completely into the urinal hole 61.

[0022] A baffle 62 is fixedly connected to the urinal, and the baffle 62 can effectively prevent urine from splashing out. A flushing port 63 is fixedly connected to the baffle 62, and the flushing port 63 is above the baffle 62, so that urine on the baffle 62 can also be flushed clean.

[0023] The pipe below the urinal 61 is connected to the sewage pool 7, the water outlet of the sewage pool 7 is fixedly connected to the water pump 8, and the pipe of the water pump 8 is connected to the anaerobic microorganism pool 9. The anaerobic microorganism pool 9 uses the metabolic characteristics of anaerobic microorganisms to decompose, metabolize and digest organic matter in the sewage, thereby reducing the organic matter content.

[0024] The anaerobic microorganism pool 9 is connected to the aeration system 10 by a pipeline. The aeration system 10 includes aeration aeration equipment and mechanical aeration equipment. Its purpose is to provide a certain sewage retention time to meet the oxygen required by aerobic microorganisms.

[0025] The aeration system 10 is connected to an aerobic microorganism pool 11 through a pipeline. The microorganisms in the aerobic microorganism pool 11 can utilize organic matter for reproduction and metabolism. The water outlet of the aerobic microorganism pool 11 is fixedly connected to a defoaming pump 12 , which can eliminate the foam generated by the flotation of bubbles in the aeration system 10 .

[0026] The defoaming pump 12 is connected to the ultrafiltration membrane filtration system 13 through a pipeline. The ultrafiltration membrane filtration system 13 retains large particles in the water that are larger than the average pore size on the surface of the membrane and allows substances that are smaller than the pore size of the membrane to pass through the membrane surface.

[0027] The ultrafiltration membrane filtration system 13 is connected to the disinfection system 14 through a pipeline, the disinfection system 14 is connected to the storage bin 15 through a pipeline, the storage bin 15 is connected to the automatic flushing system 16 through a pipeline, and the automatic flushing system 16 is connected to the urinal 6 through a pipeline.

[0028] Working principle:

[0029] Enter the toilet room 1 from the steps 4, close the toilet door 2, rotate the door buckle 3 to the right to buckle the toilet room 1, and then you can go to the urinal 10. There is a baffle 12 on the urinal, so the urine splashing is blocked by the baffle 12. The urine hole 11 is at the front of the urinal. The urinal has a low front and a high back arc, which allows the water flow to flush the urinal more completely. The flushing port 13 discharges water from above the baffle 12 to flush the urine splashed on the baffle 12.

[0030] Urine enters the sewage pool 7 through a pipe, and a water pump 8 sucks the urine from the sewage pool 7 into the anaerobic microorganism pool 9. Anaerobic microorganisms convert large molecular insoluble substances into small molecular soluble substances, and small molecular organic matter is further converted into simpler compounds. The main products include volatile fatty acids, alcohols, lactic acid, etc. The generated compounds are further converted into acetic acid, carbonic acid, hydrogen and new cellular substances. Finally, acetic acid, hydrogen, carbonic acid, etc. are converted into methane, carbon dioxide and water.

[0031] After the sewage is transformed, it enters the aeration system 10. The aeration system 10 generates bubbles by mechanical or return water impacting the air, so that the bubbles come into contact with the water body, thereby increasing the oxygen content in the water and promoting biological metabolism.

[0032] The sewage enters the aerobic microorganism pool 11 through the aeration system 10. The microorganisms in the aerobic microorganism pool 11 are mainly some facultative and aerobic bacteria, such as Proteus, Nitrosobacter, etc. Under aerobic conditions, the chemical energy generated by the reaction can be absorbed and utilized by the cells, thereby treating the pollutants in the water.

[0033] The water in the aerobic microbial pool 11 passes through the defoaming pump 12 to eliminate the foam generated on the sewage surface. The sewage enters the ultrafiltration membrane filtration system 13 through the defoaming pump 12 to further refine the large particle molecules in the treated water. The treated sewage enters the elimination system 14 through the pipeline. After the disinfection system 14 performs the final sterilization and disinfection on the sewage, it enters the storage bin 15.

[0034] The automatic flushing system 16 senses that someone has finished using the toilet and stands up, and automatically draws water from the storage bin 15 to flush the urinal 6.

[0036] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit them. Although the utility model is described in detail with reference to the above embodiments, a person skilled in the art should understand that the technical solutions described in the above embodiments can still be modified, or some of the technical features can be replaced by equivalents, and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the utility model.
