Anti-blockage regenerated water trickle irrigation system

Abstract

The invention relates to an anti-blockage regenerated water trickle irrigation system, belongs to the field of hydraulic engineering, and has an IPC (International Patent Classification) number of E02B 13 / 00. The trickle irrigation system comprises a filtering system, a measuring and controlling system, a pipe network system and a trickle irrigator. Regenerated water for irrigation sequentially passes through a sandstone filter with a typical filtering material ratio and an automatic backwashing type laminated filter, thus the contents of suspended matters, organic matters, microorganisms andthe like in the regenerated water are effectively reduced; and before irrigation, the regenerated water passes through a mesh gauze filter for further filtering out matters which easily cause blockage. The technical scheme is applicable to long-term usage of the regenerated water for agriculture and green area irrigation, is used for well solving the problems that the filtering system has poor filtering effect, the trickle irrigator, an electromagnetic valve and a water meter are easily blocked so that the performances decrease and the pipe network system is nonuniform in watering when the traditional trickle irrigation system uses the regenerated water for irrigation, and has quite broad market application prospects.

Description

technical field [0001] The invention relates to an anti-clogging recycled water drip irrigation system. It belongs to the field of water conservancy engineering, and the IPC international patent classification number is E02B 13 / 00. Background technique [0002] The increasing shortage of water resources has seriously restricted the social and economic development of our country, and urban reclaimed water has the advantages of not being affected by the climate, not competing with adjacent areas for water, being available locally, stable and reliable, and having a high guarantee rate. Within a certain range of use, it provides us with An economical and reliable new water source has been established, and the reclaimed water that can be developed and utilized in my country in the near future will reach 30 billion m 3 , Recycled water resources will become an important alternative water source in my country. As an efficient water-saving irrigation method currently used in agricu...

AI Technical Summary

Problems solved by technology

As an efficient water-saving irrigation method currently used in agriculture and green land, drip irrigation can effectively improve water production efficiency and reduce water consumption, and can also effectively reduce the transmission of pollutants, pathogens, etc. to the air medium during irrigation with reclaimed water. Reduce the risk of reclaimed water irrigation on plant quality and human health, but because reclaimed water contains suspended solids, pathogenic microorganisms and other pollutants, it will have a significant impact on the normal operation of the drip irrigation system

The filling filter material of the gravel filter used in the current drip irrigation system is mainly composed of quartz sand with a single particle size (about 2mm), which is used in the recycled water drip irrigation system, and the filtering effect is poor. At present, the filtration rate of TSS (suspended solids) is only below 30%, and at the same time, there is no clear statement on the suitability of drip irrigation emitters, solenoid valves, water meters and other control and metering equipment used in the recycled water drip irrigation system, so The current drip irrigation system is prone to clogging of the drip irrigation emitter under the condition of long-term use of recycled water, which reduces the irrigation uniformity of the pipe network system
