1, anaerobic fermentation treatment
Anaerobic fermentation is a complex biological process; feces carbohydrates, fats and proteins and other substances, in the absence of oxygen conditions and the role of microorganisms, these organic substances can be converted into methane, methane is mainly used as fuel, such as natural gas and gas, widely used in civil and industrial.
2, aerobic treatment method
The process of fermentation using aerobic bacteria is called aerobic fermentation. Aerobic treatment scale is small, can only do the final dilution after aeration, precipitation; medium scale and above, after pre-treatment and secondary dilution, can be treated according to standard activated sludge method. Add the appropriate amount of chemicals to the manure, so that the manure flocculation, and separated into liquid and dewatered sludge by precipitation.
3, high-temperature and high-pressure treatment method
Organic matter in feces, under the condition of high temperature and high pressure, after about 1h continuous oxidative decomposition can achieve better treatment effect. The capacity of the reaction tower should be determined according to the heat of the manure, reaction speed and the degree of oxidation.
4, high-temperature composting method
The feces will be mixed into the garbage according to a certain proportion, the application of high-temperature composting method for treatment. If the garbage contains high nitrogen, it is not suitable to use this method.

The treatment of feces in portable toilets
1, flushing and non-flushing suction-type portable toilets
Flushing portable toilets have a flushing device, usually the water tank is placed on the top of the toilet, and the bottom of the toilet is set up with a sewage tank.
2, recirculating flushing type portable toilet
This kind of portable toilet is equipped with intermittent aerobic and anaerobic treatment of fecal sewage device, and then add biological strains of bacteria, the use of biofilm technology, will be processed fecal sewage recycling used to flush toilets and sanitary ware.
3, dry packing type portable toilet
This kind of portable toilet does not have a flushing device, the excreta placed in the lower part of the sanitary ware of biodegradable plastic bags to undertake, every time you use a person, automatic replacement of another new plastic bags, after the use of the plastic bags will be collected and transported to the treatment plant for disposal.
4, foam blocking portable toilet
The use of foaming liquid mixture produced by the foam instead of toilet flushing, this system can meet the foaming water by collecting clean water, so maximize the savings in water resources.
5, microbial type portable toilet
Microbial type portable toilet excreta through the automatic opening of the potty into the solid-liquid separation device, the set of devices can be filtered urine, the stool will be pushed away from the separation out, and then treated separately.
