High temperature composting, biogas digesters, ecological toilets

High-temperature composting is to pile up human manure, livestock manure and straw, etc., so that bacteria and fungi can multiply in large quantities, and bacteria and fungi can decompose organic matter and release energy to form high temperature. High-temperature composting is an important way to produce farm fertilizer. High temperature is formed during the high-temperature composting process, which can also kill various germs and insect eggs.

Environmental protection, design, ecology, toilets.

It is a kind of high-tech toilet that can be flushed without water, and the whole process of use includes lighting, ventilation, whether there is an indication or not, automatic identification of urine and urine, fecal flushing, temperature control, fault judgment and warning, etc. Its intelligent operating system collects urine and automatically adds a deodorant, sterilization, disinfection, lubrication, and anti-scaling effect, so that fresh urine becomes an odorless blue-green liquid and is stored as a rinsing liquid.

An ecological toilet is a toilet with a virtuous cycle of its own. Ecological toilets generally have three characteristics of ecological building tenants: first, there should be a biogas purification tank underground, instead of an ordinary biogas tank, which is a core facility; Second, the roof should be covered with soil (for planting or water storage and aquaculture) or set up a solar energy utilization device; The third is that the wall should be vertically greened, so that after many years, the ecological toilet will become a green ecological building.

The main types of ecological toilets are garden-type, comprehensive type (integrated with housing, office and business buildings), scaffolding type (planting grapes or vines, etc.), ordinary type and scenic area type.

Gas is a flammable gas produced by the action of microorganisms (fermentation) of some organic substances (such as straw, weeds, leaves, human and animal manure and other wastes) under certain temperature, humidity and acidity conditions, isolating the air (such as using a biogas digester). Biogas is a mixture of gases containing methane 60 70, carbon dioxide, hydrogen sulfide, nitrogen and carbon monoxide. It contains a small amount of hydrogen sulfide, so it has a slight odor.

Fermentation is a complex biochemical change with many microorganisms involved. The reaction is roughly divided into two stages: (1) microorganisms degrade sugars, fats, and proteins in complex organic substances into simple substances, such as lower fatty acids, alcohols, aldehydes, carbon dioxide, ammonia, hydrogen, and hydrogen sulfide.

2) By the action of methane bacteria, some simple substances are turned into methane.
