Title:
INTENSIVE DAIRY FARM BREEDING WASTEWATER DRIP-IRRIGATION SYSTEM AND OPERATION MANAGEMENT METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/178841
Kind Code:
A1
Abstract:
Disclosed are an intensive dairy farm breeding wastewater drip-irrigation system and an operation management method therefor, which relate to the technical field of wastewater treatment. The system comprises a grating (24), a water distribution well (25), animal housings (26), a micronano bubble generation device (27), a water source pre-treatment system, an advanced treatment system and a drip-irrigation pipe network. The water distribution well (25) is connected to water inlets of the animal housings (26) and an inlet of the micronano bubble generation device (27) by means of pipelines, respectively; an outlet of the micronano bubble generation device (27) is connected to a purified water inlet of the advanced treatment system; and sewage outlets of the animal housings (26), the grating (24), an inlet and an outlet of the water source pre-treatment system, and a sewage inlet and outlet of the advanced treatment system are successively connected to an inlet of the drip-irrigation pipe network in sequence. In the method, an advanced treatment method for complicated quality of breeding wastewater and the operation management method for reusing the breeding wastewater in an agricultural irrigation system by means of the drip-irrigation technology are comprehensively taken into consideration during design. The problems, such as the blockage of an irrigation emitter due to the reuse of breeding wastewater in farmland, are effectively solved, the system operates safely and allows safe and effective use of breeding wastewater.
