Comprehensive treatment and recycling device for agricultural polluted wastewater

Abstract

The invention provides a comprehensive treatment and recycling device for agricultural polluted wastewater. The comprehensive treatment and recycling device comprises a treatment tank, a reservoir anda drainage ditch, wherein the drainage ditch is communicated with the side wall of the top end of the treatment tank; a connecting pipe is arranged between the treatment tank and the reservoir; an electric valve is installed on the connecting pipe; two fixed columns are fixedly and symmetrically arranged on the two sides of the upper surface of the treatment tank; and a control switch block is installed on the outer side surfaces of the fixed columns. The comprehensive treatment and recycling device for agricultural polluted wastewater in the invention can be directly built near a sewage source, such as a breeding factory and a household product processing factory; the treatment tank is communicated with the drainage ditch, so the agricultural polluted wastewater can be directly discharged into the treatment tank for treatment, treatment cost is low, treatment speed is high, treated wastewater can be directly discharged into the reservoir for agricultural water conservancy irrigation,and use is convenient; and a filter cartridge can ascend and descend under the driving of a stepping motor and a drive screw, so a filter screen is convenient to clean and replace, operation is easy,and maintenance is simple.

Description

technical field [0001] The invention relates to the technical field of agricultural water conservancy, in particular to a comprehensive treatment and reuse device for agricultural polluted wastewater. Background technique [0002] Agricultural wastewater is wastewater discharged from crop cultivation, livestock raising, and agricultural product processing. Wastewater is mainly divided into farmland drainage, feedlot drainage, agricultural product processing wastewater, etc. Agricultural wastewater has a large amount of water and has a wide range of impacts. According to the statistics of the United States in 1977, it is 5 to 6 times larger than the increase in BOD in water bodies caused by urban sewage and industrial wastewater pollution, and the affected water area accounts for 68% of the total water area. [0003] Most of the existing agricultural polluted wastewater treatment devices need to concentrate the polluted wastewater to the wastewater treatment plant for treatm...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing agricultural polluted wastewater treatment devices need to concentrate the polluted wastewater to the wastewater treatment plant for treatment. In areas with inconvenient transportation, due to the high construction cost, it is difficult to lay pipelines or canals for centralized sewage, and the existing The traditional agricultural polluted wastewater treatment device is time-consuming and laborious, and cannot be applied to agricultural water conservancy in time after treatment. At the same time, the filter device is not easy to clean, inconvenient to operate, and troublesome to use. Therefore, we propose a comprehensive treatment and reuse device for agricultural polluted wastewater.
