Microwave comprehensive treatment system and method for manure wastewater in pig farm

Abstract

The invention discloses a microwave comprehensive treatment system and method for manure wastewater in a pig farm. The microwave comprehensive treatment system comprises a cloth bag type plate-and-frame filter press, a first pipeline, a buffer tank, a second pipeline, an array type microwave filtering device, a third pipeline, a microwave waste gas high-temperature pyrolysis device, a fourth pipeline and a purified water storage tank, wherein the cloth bag type plate-and-frame filter press, the first pipeline, the buffer tank, the second pipeline, the array type microwave filtering device, the fourth pipeline and the purified water storage tank sequentially communicate with each other; and the array type microwave filtering device, the third pipeline and the microwave waste gas high-temperature pyrolysis device sequentially communicate with each other. The microwave comprehensive treatment system for the manure wastewater in the pig farm is large in water treatment capacity, high in efficiency, good in effect, free of harmful gas emission and small in occupied area; and the treatment of the whole system can be completed in a factory building and is not influenced by weather and climate changes, a huge aeration tank does not need to be excavated outdoors, and the system is low in cost, stable in system operation and high in risk resistance, and is suitable for treating manure wastewater of pig farms and the like.

Description

technical field [0001] The invention relates to a microwave comprehensive treatment system and treatment method for manure and wastewater in pig farms, belonging to the field of manure and wastewater treatment. Background technique [0002] The supply of pork in our country has always been in short supply. In recent years, the country has vigorously advocated scientific pig raising, requiring intensive and standardized management. All rural areas in various places are promoting the industrialization of large and small pig raising. At present, the biggest problem in pig farms is the excrement produced by pig raising. How to dispose of sewage and flushing wastewater. Traditional pig farms lack relevant facilities, the stench is overwhelming, feces and wastewater are discharged indiscriminately to pollute local water bodies, and the dirty environment and pollution discharge restrict the scale construction of pig farms. [0003] As the country's environmental protection require...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the problems in the prior art that there is no stable and economical treatment method for feces without waste water, the traditional biological method has huge initial civil construction investment, occupies a lot of land, has poor anti-risk ability, and is difficult to adapt to the complicated situations in rural areas of our country. The present invention provides a pig raising The microwave comprehensive treatment system and treatment method for manure and wastewater on site, combined with activated carbon filtration and microwave high-temperature anaerobic activation and regeneration technology, adopts industrialized filtration technology when the cost of wastewater treatment is within an acceptable range (comprehensive wastewater treatment cost 40-60 yuan / ton) , factory operation, small footprint, good processing effect, good stability
