The following technical solutions can be used to achieve the purpose of the present invention. A mobile green environmentally-friendly public toilet includes a toilet installed on a fixed or movable seat frame, and is provided with a squatting position, a water tank, a cleaning facility, and a ventilation light window. The utility model is characterized in that a BMS biological treatment room and a multifunctional management room are respectively provided on two sides of a toilet door. The BMS biological treatment room is provided with a sewage treatment tank connected to the squatting sewage collection tank, and its water outlet is connected with a storage tank (including a toilet flushing tank and a human contact washing tank). The storage tank is connected with a toilet tank and a pipeline through a pipeline. The pump is connected to the plumbing line. The multifunctional management room is equipped with storage tanks (including toilet flushing tanks, human contact washing tanks), equipment and equipment control cabinets, and newspaper and magazine racks. The squatting position of the bathroom can be a gourd shape, and a child seat that can be turned is provided on the wall of the bathroom, and a safety belt is connected to the seat. There are handrails on the wall near the squatting position, ventilation windows above the BMS biological treatment room door, and lighting windows on the bathroom roof. The entire toilet is installed on a support that can be adjusted to rotate, and a movable sliding cymbal is installed under the support. BMS system

The BMS bioprocessing chamber contains a BMS system. The BMS system is Best- Microorganism-System, which is mainly composed of (a) porous support, (b) multi-flora microorganisms coexisting on the porous support, and (c) micro-bubble supply equipment (see Figure 3). Porous carrier

The preferred porous carrier of the present invention is a wooden carrier, in which components that are liable to cause spoilage have been removed, but cellulose, lignin and pentosan components remain. The porosity of the present invention is 75-85%, and when placed in water, it can be semi-suspended in water, thereby increasing the gas, liquid, and solid three-phase contact areas.

In addition, the wooden carrier of the present invention has pores of different sizes and depths, thereby forming a certain degree of anaerobic, facultative and aerobic regions, thereby providing suitable growth environments for different types of microorganisms. Multiflora

Symbiosis and coexistence on a porous carrier A multifamily microorganism is an aggregate composed of a variety of bacteria, which contains microorganisms selected from the group consisting of photosynthetic bacteria, lactic acid bacteria, yeasts, actinomycetes, and the like.

The microorganisms that can be used in the present invention are not particularly limited, and may be any bacteria that decompose and use various pollutants such as organic substances, sulfides, nitrogen oxides, and organic phosphorus in sewage. As for the main types of microorganisms mentioned above, photosynthetic bacteria are mainly used to break down low fatty acids and aromatic compounds; lactic acid bacteria mainly break down proteins and substances such as glucose, lactic acid, acetic acid, and propionic acid; yeasts are mainly excellent for high-concentration organic wastewater Effect; Actinomycetes mainly degrade a variety of organic substances including aromatic compounds.

Representative examples of microorganisms include, but are not limited to: ammonium bacteria, nitrifying bacteria, denitrifying bacteria used to eliminate NH ₃ ; sulfur sulfide bacteria (such as Thiobacillus) used to eliminate sulfide, filamentous sulfur bacteria (such as Bayesian Sulfur bacteria, sulfur-producing bacteria), photosynthetic sulfur bacteria (such as green sulfur bacteria, red sulfur bacteria); ammoniating bacteria (such as Bacillus), nitrifying bacteria, denitrifying bacteria, phosphorus bacteria (such as sand Lectobacillus). These microorganisms can be commonly used in the field, and can also be obtained by conventional methods from environments such as garbage dumps and wastewater treatment plants. Micro bubble supply equipment

The micro-bubble supply device is located under the wooden carrier to provide oxygen for the multi-flora microorganisms.

The air supply tube of the microbubble supply device has many fine pores (preferably "I" pores), and the The cross section has a certain slope, so that the micro-bubbles are not only small and dense, but also automatically cover to prevent blockage when the air supply is stopped.

The BMS system reactor simulates a natural environment ecosystem with a long food chain consisting of many types of microorganisms. The BMS flora residing in the carrier is usually dormant. When exposed to wastewater and biological aids, the flora quickly changed from dormant to active. Organic matter in the wastewater is adsorbed to the bacteria within a short time (about 10-30 minutes), and the soluble matter directly penetrates into the cells. The nutrients entering the cells are converted into simple inorganic substances such as carbon dioxide and water by a series of biochemical reactions under the action of intracellular enzymes. At the same time, energy is generated. Microorganisms use the energy released from the breath and the intermediate products produced during the oxidation process to synthesize cellular substances, causing the bacteria to reproduce in large numbers. Microorganisms continue to carry out biological oxidation, and organic matter in the environment is continuously reduced, so that sewage is purified.

The BMS system used in the present invention has the following main features;

(D BMS system simulates the natural ecological environment. Its purification process and flow principle are different from traditional biological treatment processes. The BMS system can not only rapidly decompose organic substances, suppress and eliminate the generation of odors such as hydrogen sulfide, ammonia gas, but also make the entire process No excess sludge is discharged.

(2) The BMS biological treatment system is different from the traditional biological treatment method. The system has neither the clogging phenomenon of the traditional biofilm method nor the sludge swelling phenomenon of the traditional activated sludge method; oxygen transfer efficiency, oxygen utilization ratio, treatment efficiency, Biomass, activity, economics and other indicators are significantly better than traditional biological treatment methods; The system has high-efficiency nitrogen and phosphorus removal and deodorization effects that traditional biological treatment methods cannot replace.

(3) The wooden carrier of the present invention is different from the currently used biological carriers. The carrier has a moderate specific gravity within the carrier and forms an ecological system of biological species with a reasonable number distribution.

(4) An efficient micro-aeration system with self-resistance can not only generate uniform fine bubbles, but also not block, and provide a sufficient oxygen source for the microbial flora. The water-gas ratio of the treatment system is about 1 / 3-1 / 2 of traditional biological treatment, with low energy consumption and high oxygen utilization rate.

(5) The micro-bubble supply equipment provides the best conditions for the growth and reproduction of microorganisms.

(6) The equipment has high processing efficiency (see Figure 4 for COD processing efficiency), small footprint, low investment cost, and high degree of integration. Example:
