| 摘要: |
| 【目的】滴灌是再生水灌溉利用中比较可靠有效的技术模式之一，能有效降低作物环境的污染风险。再生水滴灌时灌水器易发生堵塞，进而影响滴灌系统的安全运行。因此，开展再生水滴灌灌水器堵塞研究是非常有必要的。【方法】本文在广泛搜集分析文献的基础上，对目前国内外再生水滴灌条件下灌水器生物堵塞的研究概况进行了归纳总结。【结果】系统阐述了再生水滴灌灌水器的堵塞原因，尤其是探究了生物堵塞的发生机理，总结了再生水滴灌系统灌水器防止生物堵塞的措施，在此基础上，进一步探讨了未来研究发展趋势。【结论】作为灌水器堵塞的主要类型之一，生物堵塞可以通过加氯、调节流速、调节滴灌频率等方式缓解，具体措施还应与实际情况相结合。 |

| Abstract: |
| 【Objective】Drip irrigation is one of the reliable and effective technical modes in reclaimed water irrigation and utilization, which can effectively reduce the pollution risk of crop environment. Emitter clogging is a key problem that affects the operation safety and service life of reclaimed water drip irrigation system.Therefore, it is very necessary to carry out research on the clogging of reclaimed water drip irrigation emitters.【Method】Based on the extensive collection of analytical literature, this paper summarizes the current research situation of emitter clogging in reclaimed water drip irrigation at home and abroad.【Result】This paper outlines the clogging causes of drip irrigation with reclaimed water, especially explores the mechanism of biological clogging. It also summarizes the anti-clogging measures of emitters in reclaimed water drip irrigation system. On this basis, this paper further discusses the development trend of future research.【Conclusion】As one of the main types of emitter clogging, biological clogging can be alleviated by chlorination, adjusting flow rate, and adjusting drip irrigation frequency. The specific measures should also be combined with the actual situation. |
