Most of the research on the treatment of train manure and sewage is the treatment method after collection. Some schools and research institutions have also proposed the scheme of direct treatment on the train, and some have applied for patents. These schemes also use biological treatment methods. However, due to the fact that it cannot be used in the actual train operating environment (high speed, vibration, external wide temperature range) and operating mode (only about half of the time is running, and there is no electricity, gas, or water in the car when parking), the limited space that the train can provide internal cleansing but failed to put it into practice

Embodiment Construction
[0015] figure 1 A mobile toilet excrement purification treatment method is shown, the steps are as follows:
[0016] (1) Coagulation, solid-liquid separation, extrusion dehydration: flush the urinal with 1-1.5 liters of clean water every time the person goes to the toilet, and the mixture after flushing falls into the coagulation chamber, and polychlorination is added in the coagulation chamber After aluminum and stirring for 4 minutes, it is sent to the solid-liquid separator for direct solid-liquid separation, and the separated sewage is sent to the clean room, wherein the maximum length of the solid in the liquid after separation is less than 1mm; the separated solid part (feces Solid parts, toilet paper and other possible solids) are extruded into cake-like solids with a water content of 75-85%, and sent to the collection box;
[0017] (2) Purification pretreatment: The controller measures the pH value of the sewage separated from step (1) according to the probe in the pu...

The invention discloses a mobile toilet excrement purification treatment method. In the method, solid-liquid separation is adopted on excrements of a mobile toilet for two times and a special purifying agent is added to carry out rapid flocculation and purification; solid dirt is extruded, dehydrated, packed and collected; and muddy sewage is directly reused in the mobile toilet after being purified, sterilized, discolored and deodorized to become reclaimed water reaching the standard. The invention has few steps and short treatment time, clears the excrements at any time after using and is suitable for treating the excrements in mobile toilets and temporary toilets in trains or passenger ships.
Description
[technical field] [0001] The invention relates to purification treatment of human excrement, in particular to a method for purification and treatment of excrement sewage suitable for mobile toilets such as trains and ships, and temporary toilets. [Background technique] [0002] At present, the biological treatment method is basically used in the treatment of human feces in my country. Using the principles of sedimentation and anaerobic fermentation, the organic matter in the feces is decomposed into stable inorganic matter, and the perishable raw sludge is converted into stable cooked sludge. Regularly remove the sludge and transport it to landfill or use it as fertilizer. The processing time generally takes 3 months. For the feces of mobile toilets such as trains and ships, most of them are directly sprinkled on both sides of the railway or in rivers and lakes. In recent years, the State Environmental Protection Administration has attached great importance to train excrem...
