An ecological cycle method based on resource utilization of kudzu root wastewater and waste residue

Abstract

The invention provides an ecological circulation mode based on resource utilization of radix pueraiae wastewater and waste residue, comprising the following steps: waste collection and pretreatment, wastewater reuse, wastewater and waste residue fermentation, culture of earthworm and housefly larvae, culture of algae and water weeds, culture of fish and shrimp and plantation of radix pueraiae. Resource utilization of wastewater and waste residue from radix pueraiae production process, in-plant kitchen garbage and sludge and sewage from a septic tank is realized; radix pueraiae slag and radix pueraiae powder wastewater are utilized and kitchen garbage and septic-tank contents fermented products are added for culture of housefly larvae, earthworm and algae and water weeds as a feed for fish farming, and an organic fertilizer obtained by mixing soil obtained after culture of earthworm and housefly larvae and bottom mud of a fishpond is applied into a radix pueraiae plantation base, so as to establish an ecological circulation mode. By the ecological circulation mode, zero emission is realized, secondary pollution to the environment will not be caused, the environment can be protected, waste treatment cost is saved, and good economic benefit also can be generated.

Description

technical field [0001] The invention relates to the technical field of environmental resources and biological breeding, in particular to an ecological cycle method based on resource utilization of kudzu root wastewater and waste residue. Background technique [0002] Pueraria lobata is widely distributed in most areas of my country such as Hubei, Hunan, Shaanxi, Anhui, and Guangdong. It is loved by people because it is rich in starch, dietary fiber, flavonoids, polysaccharides, etc., and has high economic value and medicinal value. The flavonoids contained in kudzu root have good effects on lowering blood pressure and blood lipids, anti-oxidation, regulating estrogen levels in the body, and improving circulation. In addition, it is also rich in minerals necessary for the human body such as calcium, iron, copper, and tin. Nutrition for everyone. [0003] Although my country's current kudzu powder production process is relatively mature and has a relatively advanced wastewate...

Problems solved by technology

[0003] Although my country's current kudzu powder production process is relatively mature and has a relatively advanced wastewater reuse system, a large amount of wastewater rich in flavonoids, starch and other nutrients, as well as cellulose, hemicellulose, and lignin, will still be produced every year. , pectin and other components, if they continue to be directly discharged into the environment, it will not only cause harm to the surrounding environment, but also cause a waste of the rich nutrients it contains

[0004] At present, the kudzu root planting bases in my country are basically located in rural areas, and kudzu powder manufacturers are also near the planting bases. In addition to the impact on the rural ecological environment due to improper disposal of waste water and waste residues, kitchen waste and septic tanks generated by personnel activities in the factory area The treatment cost of the sludge and other substances in the kudzu powder is also relatively high, which brings a certain economic burden to the kudzu powder manufacturers.
