Gannan Process Mobile Toilet
Mobile toilets with various processes in Gannan mainly include sewage-storage type, biochemical treatment type, and waterless or low-water type.
Sewage-storage mobile toilets: This is a relatively common type. Its working principle is to collect excrement in a sealed tank and regularly transport it to a regional treatment center by special vehicles. The technical requirements of this model are relatively simple, mainly focusing on the tightness of the tank and the convenience of transportation. However, it is highly dependent on the subsequent transportation system. If the transportation is not timely or problems occur during the process, it may lead to tank overflow, affecting normal use and potentially causing pollution risks to the surrounding environment.
Biochemical treatment mobile toilets: These toilets are equipped with small treatment units inside the tanks. They carry out preliminary decomposition and deodorization of excrement through microbial degradation or the addition of chemical agents. Taking the Gannan dry microbial toilet (model fhjc - 02) produced by Dalian Fuhua Hengrun Industrial Co., Ltd. as an example, it uses Fuhua Jicheng brand biological agents to conduct in-situ treatment of human excrement in a composite biological reactor (hbr). The treatment process is odorless, and the treated water can be reused for toilet flushing, achieving a fully enclosed cycle, zero secondary pollution, and zero emissions. This significantly reduces the frequency of transportation and the pressure on the environment.
Waterless or low-water mobile toilet equipment: Under specific conditions, this type of mobile toilet is also used in Gannan. It employs physical separation and evaporation technologies, significantly reducing dependence on water resources and the amount of sewage generated. This technological approach is of great application value in Gannan, a region with relatively scarce water resources, as it not only meets people's basic toilet needs but also complies with local sustainable development requirements.
