造纸废水灌溉的可行性及发展前景分析

Analysis on Feasibility and Development Prospect of Irrigation by Papermaking Wastewater

分析造纸废水灌溉存在的一些问题及其可行性和发展前景,指出:污水灌溉要因地制宜、合理规划,灌溉前要对水质进行监测,且使用污水中的含量不能超过所灌溉土壤的净化能力。同时,要结合当地水源情况、土壤质地、作物种植的种类及生长阶段等情况,合理利用污水进行灌溉,这对缓解我国水资源日益紧张的供需矛盾,保护生态环境,提高经济效益有重要意义。

The existed problems,feasibility and the development prospect of irrigation by papermaking waste water were introduced.It pointed out that measures must be taken to suit to local conditions and layout reasonably.Water quality must be monitored before irrigation,and the concentration of pollution content cannot exceed the purity capability of the irrigation soil.Meanwhile,waste water irrigation should be combined with the local water resources,soil texture,crop species and growth stage,made rational use of the waster water for irrigating.It was significant to alleviate the water shortage of the country,protect ecosystem and improve economic benefit.
