Description
Technical Field
The invention belongs to the technical field of environment-friendly sanitary facilities, and particularly relates to a mobile toilet.
Background
The mobile toilet refers to a facility which can be moved integrally, is arranged at a place or a place with fixed or temporary requirements, and provides toilet service for the public and customers. The movable toilet is generated from temporary and staged demands of people on the toilet in certain specific occasions, such as workplaces of building construction sites, shipbuilding docks and the like, and the movable toilet is arranged on the docks and the construction site for reducing the time of workers for going to and going to fix the toilet and improving the labor efficiency. Temporary toilet requirements for large audiences at large gatherings, sporting events, etc. Because the quantity and the layout of the urban public toilets are deficient, the government lays the mobile toilets in the section where the fixed public toilets are difficult to construct so as to make up the defects of insufficient quantity supply and unreasonable layout of the public toilets. In addition, the portable lavatory is more practical in some remote areas. In those areas, due to water shortage, the septic tank and the soil absorption method used in the traditional public toilet for sewage treatment cannot be adopted. The use of mobile toilets also reinforces the link between large activities and health and environmental factors, especially as this activity is expected to derive a great deal of toilet demand. These mobile facilities can be offered for a short lease to a large temporary group of people. In some special activities, the portable lavatory facility may be placed on site and retrieved after the activity is completed. The mobile sanitary facility can also provide temporary sanitary service for the post-disaster area where long-term disaster relief measures are taking place.
According to statistics, each public toilet flushed by water in China consumes thousands of tons of water every year, and some of the water consumption is as high as 5 and 6 tons. The sewage generated by flushing the toilet with water has huge discharge capacity, and the volume and the weight of the sewage are hundreds of times of those of solid domestic garbage, so that the consideration of water consumption is an important factor when the mobile toilet is designed.
The conventional water-flushing type mobile toilet or the non-water-flushing suction type mobile toilet needs to suck in time when the specified number of people is used due to the small capacity of the sewage tank, otherwise, an overflow event is easy to happen, and the suction frequency is high. Biological strains are added into the circulating water flushing type mobile toilet, the fermentation and decomposition of the fecal sewage are accelerated by applying a biological membrane technology, and then the treated fecal sewage is recycled to flush the toilet sanitary appliance through a filtering device, so that the precious water resource is saved, the fecal sewage suction frequency is reduced, but the wide use of the fecal sewage is limited due to the higher cost. There is also a dry packing type mobile toilet without a water flushing device, and the excrement is received by a degradable plastic bag placed on the lower part of the sanitary appliance, and when the toilet is used by one person, another new plastic bag is automatically replaced, and after the toilet is used up, the plastic bags are collected and transported to a treatment plant for disposal. Although the portable lavatory saves water resources, it cannot immediately treat excrement and peculiar smell, and the transportation of sewage is very inconvenient.
