It is understood that the use of municipal sludge production of organic compound fertilizer this new technology is currently being fully applied. This technology not only makes urban sludge a renewable resource, but also fundamentally solves secondary pollution caused by improper use of sludge containing heavy metals, pathogenic bacteria, and toxic organic matter. Northwest A&F University uses aerobic fermentation methods to harmlessly treat urban sludge, which can reduce odor, reduce water, kill pathogenic bacteria and parasites (eggs), get composted sludge compost, and compost sludge compost. , Crushing, adding the right amount of chemical fertilizers and beneficial microorganisms at the same time, made organic compound fertilizers and bio-organic compound fertilizers. It is understood that there are currently more than 300 sewage treatment plants that have been built in China, and most of them lack effective sludge treatment facilities and have to send sludge to landfills for disposal. In fact, the “urban sludge†solid material obtained during the purification of sewage contains a large amount of organic matter and plant nutrients and can be used as a fertilizer and a soil conditioner.
