471 results about "Human waste" patented technology

Human waste (or human excreta) refers to the waste products of the human digestive system and the human metabolism, namely feces and urine. As part of a sanitation system that is in place, human waste is collected, transported, treated and disposed of or reused by one method or another, depending on the type of toilet being used, ability by the users to pay for services and other factors.

Method of treating organic wastewater and sludge and treatment apparatus therefor

The present invention has an object to provide a process and an apparatus for efficiently recovering magnesium ammonium phosphate (hereinafter referred to as “MAP”) crystals of high purity and good quality in the technique of removing phosphorus and the like as MAP crystals from wastewater containing high concentration organic substance, phosphorus and nitrogen such as a digested supernatant liquor of human waste sewage and septic tank sludge, a digested liquor of sludge, chemical plant wastewater, and simultaneously recovering the MAP crystals. As the means to achieve such an object, the present invention provides a sludge treatment process comprising treating a sludge mixed liquor formed in the biological treatment system for organic wastewater in an anaerobic digestion tank to effect the digestion of sludge, simultaneously adding a magnesium source to the anaerobic digestion tank to allow crystals particles of MAP to form and grow in the anaerobic digestion tank, withdrawing a sludge mixed liquor containing the crystals of MAP from the anaerobic digestion tank, separating and recovering solids containing MAP crystal particles from the withdrawn sludge mixed liquor, and returning part of the sludge mixed liquor after separation and recovery of MAP crystal particles to the anaerobic digestion tank.

Device For Manufacturing Organic Compost From Excremet

The present invention relates generally to a device for manufacturing organic compost from human excrements in a toilet to automatically transform human excrements into organic compost. More particularly, the present invention comprises a transport belt installed under a seat disposed on a main body of a toilet, capable of transporting excrements; a stirring room mixing with a stirring blade the excrements transported by the transport belt; a microorganism hopper installed on the upper side of the stirring room, feeding microorganisms into the excrements stirred in the stirring room; a muck collector receiving and storing the excrements crushed in the stirring room; a liquid collector receiving and evaporating urine fallen from the transport belt; an air purifying room drying excrements and urine in the main body, purifying and discharging air through an exhaust pipe; and a controller installed at a side of the main body, controlling electrical operation of the above components. The device for manufacturing organic compost from human excrements in a toilet according to the present invention has advantages that water consumption in the toilet is reduced, contamination of water and environment is reduced since excrement treatment / purifying facility is not required, and organic compost for planting crops is also supplied.

Novel water-saving water closet pan and designing method

ActiveCN103556691ASolve wasting waterSolve the problem of easy clogging of sewersWater closetsFlushing devicesHuman wasteEngineering
The invention discloses a novel water-saving water closet pan and mainly relates to the technical field of water closet pans. As for pedestal pans and squatting pans in modern urban families and public places, water consumption is high, the water waste is extremely serious, unclean flushing sometimes occurs, and unfavorable influences on public hygiene are caused. As for modern rural toilets, old open-type flushing-free toilets are dominant, environmental hygiene is extremely poor, and high water consumption of modern flushing water closet pans is greatly related to the phenomenon. A piston of the water closet pan can move relatively to a water closet pan port (the piston reaches the lower portion of the water closet pan port), human body excrement can be directly moved to a thick channel of the water closet pan to be rotated, the flushing water pressure of the water closet pan is high, therefore, a lot of water is saved, the flushing of the water closet pan is clean, a sewer is not prone to be blocked, a lower port of the water closet pan is sealed by the pistonto be isolated from outside space and a sewer lineeffects of air sealing are better than those of keeping water and sealing peculiar smell by drain traps in traditional water closet pans, meanwhile, collection and usage of human body excrement are facilitated, and the water content of the excrement is greatly reduced so that the collected substance content can be increased, and the workload is reduced.

Cleaning machine for human wastes

The invention discloses a cleaning machine for human wastes. The cleaning machine comprises a fully automatic processor which is provided with a dirt discharge barrel, a negative pressure device, a hot water device, a hot air device, a packing device, a positive pressure device and a control device, adaptive underwear which is matched with the fully automatic processor, is provided with a waste collecting region, a defecation discharge outlet, a hot water output tube and a hot air output tube and is made of a flexible fabric, and a corresponding pipeline which connects the fully automatic processor with the adaptive underwear. Compared with the conventional automatic defecation processing system, the cleaning machine for the human wastes has the advantages that: 1, nursing personnel do not need to contact the defecation, so that the working environment is improve greatly when the nursing personnel clean the dirt discharge barrel, and the development of nursing practice is facilitated; and 2, the adaptive underwear is taken as a toilet stool and is flexible and comfortable, so that a user can wear the adaptive underwear for a long time, put on or off the toilet stool without the help of the nursing personnel, and start the cleaning machine for the human wastes at any time to defecate, and the cleaning machine for the human wastes is convenient to use.
