Abstract

The physico-chemical characteristics of sugar industry effluent were measured and some were found to be above those limits permissible in the Indian irrigation water standard. A pot study was initially conducted to study the effects of different concentrations (20%, 40%, 60%, 80% and 100%) of sugar factory effluent on seed germination, seedling growth and biochemical characteristics of green gram and maize. A similar study was also carried out using the aquatic plants, water hyacinth and water lettuce. The higher effluent concentrations (above 60%) were found to affect plant growth, but diluted effluent (up to 60%) favored seedling growth.

摘要

对制糖工业废水的物理化学特性进行了测量，发现其中一些特性超出了印度灌溉用水标准允许的限值。最初进行了一项盆栽研究，以研究不同浓度（20%、40%、60%、80%和100%）的制糖厂废水对绿豆和玉米种子萌发、幼苗生长及生化特性的影响。还使用水生植物凤眼莲和水莴苣进行了类似的研究。结果发现，较高浓度的废水（超过60%）会影响植物生长，但稀释后的废水（高达60%）有利于幼苗生长。
