For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] The utility model discloses a mobile toilet for treating waste materials, such as Figure 1 As shown, it includes a box body 1 with multiple compartments, a solar charging panel 2 arranged on the box body 1, a toilet arranged in at least one compartment and a water storage tank arranged in the box body 1, and the side wall of the compartment in which the toilet is arranged is provided with a door 13; the toilet is connected with the collection tank, the pretreatment device and the sewage treatment device in sequence; the toilet can be a squat toilet or a sitting toilet. The solar charging panel 2 supplies power to all electrical equipment in the mobile toilet, including but not limited to lights, controllers, etc. The collection tank realizes the caching of fecal water and reduces the fluctuation degree of the liquid level in the pretreatment device. Figure 1 The figure shows an example of a mobile toilet having three compartments and a toilet in each compartment.

[0024] like Figure 2As shown, the pretreatment device includes a pretreatment box 41 and a partition 42 arranged in the pretreatment box to separate the pretreatment box into a sedimentation area and a clear liquid area, the bottom and both sides of the partition 42 are connected to the pretreatment box 41 and the top of the partition 42 is lower than the top of the pretreatment box 41, the bottom of the sedimentation area is provided with a waste inlet 43 connected to the collection tank and the top is provided with a concentrated slag extraction port 44, and the clear liquid area is provided with a pumping pump 45 for pumping liquid from the clear liquid area to the sewage treatment device.

[0025] The concentrated slag precipitated in the precipitation area can be manually collected through the concentrated slag extraction port 44 and used as fertilizer, or an extraction pump can be placed in the concentrated slag extraction port 44 for extraction.

[0026] The pretreatment device is formed by separating the pretreatment box 41 with a partition, and has a simple structure. Since the collection pool realizes the caching of manure water, after the manure water enters through the bottom of the sedimentation area, the fluctuation of the liquid in the sedimentation area can be greatly reduced, the structure of the pretreatment box 41 is simplified, and the manufacturing cost is further reduced. After the manure water is precipitated in the sedimentation area, the clear liquid above flows to the clear liquid area through the upper end of the partition, and the liquid in the clear liquid area can be further precipitated. The pretreatment device has a simple structure and is easy to manufacture.

[0027] like Figure 3 As shown, the sewage treatment device includes a box body 51, a water distribution pipe 52 placed at the bottom of the box body 51 and connected to the liquid pump 45 at one end, a filter structure 53 placed above the water distribution pipe 52 and a drain outlet placed above the filter structure 53. Water uniformity holes are evenly distributed around the water distribution pipe 52. The filter structure 53 includes at least 3 layers of filter fillers, and the particle diameter of each layer of filter fillers gradually decreases from bottom to top.

[0028] The sewage treatment device uses at least three layers of filter fillers to achieve filtration, and the particle diameter of each layer gradually decreases from bottom to top to ensure the filtration quality, and by arranging a water distribution pipe 52 in the box body 51, the water distribution pipe 52 is evenly provided with water holes to achieve uniform water distribution, effectively improving the uniformity of water intake. A valve can be set on the drain port to achieve drainage control.

[0029] With the above structure, a collection tank is used to cache the fecal water, reducing the volatility of the fecal liquid in the pretreatment device, so that the pretreatment device can separate the concentrated residue and the supernatant, and then the sewage treatment device is used for filtration to meet the requirements of direct discharge. With the above structure, the pretreatment device can separate the concentrated residue and the supernatant, and the sewage treatment device only needs to filter the supernatant to directly discharge, reducing the structural complexity of the sewage treatment device and reducing costs.

[0030] The above structure can meet the requirement of direct discharge of manure water after treatment, and at the same time, the structure is simple and the manufacturing cost is greatly reduced.

[0031] In order to facilitate hand washing, a wash basin 3 is provided on the box 1, and the drainage hole of the wash basin 3 is connected to the water reservoir through the second filter structure. The drainage hole of the wash basin 3 is connected to the water reservoir through the second filter structure to realize the recycling of hand washing water. The second filter structure is a filter cotton or sand and gravel filter layer.

[0032] There are many ways to implement the filter structure 53. The following structure can be adopted based on comprehensive cost and filtering effect: the filter structure 53 has three layers, from bottom to top: a crushed stone filter layer, an activated carbon filter layer and a sand and gravel layer.

[0033] In order to further realize the utilization of rainwater, a water collection fence 11 is arranged around the top of the box body 1, and the solar charging panel 2 is arranged on a pad 12.

[0034] In order to further improve the cleanliness of the water extracted by the liquid pump 45 and reduce the filtration burden of the rear-end sewage treatment device, a fixed frame is set in the middle of the clear liquid area, and the liquid pump 45 is placed in the fixed frame. The middle here is the middle in height. It is set in the middle to avoid extracting sediments that are further precipitated in the clear liquid area.

[0035] The mobile toilet in this scheme takes into account the actual situation in power-deficient areas, adopts a simple and easy-to-operate treatment process to achieve the treatment and discharge of human feces and sewage; and adds the assistance of the solar energy system to meet the control and operation of the entire system. It has a simple structure and low production cost, and is suitable for use in areas with small flow of people, such as poor areas, mountainous areas, and scenic spots with small flow of people.

[0036] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
