摘　　要：斜生栅藻（Ｓｃｅｎｅｄｅｓｍｕｓ ｏｂｌｉｑｕｕｓ）引种至山东禹城辛店洼碳酸盐型水中后，在补加必需营养盐、充气的条件下培养，可以高速增长；试验结果表明，经过３轮栅藻培养、收获，可使盐碱水得到一定程度的淡化，经过 ３６ｈ的培养，水中主要八大离子的清除率分别达 ４８ ．５％， ５． ９％，７７．５％，７４．５％，２８．２％，４６．７％，１００％和 ５３．１％Scenedesmus obliquus, inoculated in the carbonate hard water in the Yucheng County, Shangong Province, was observed to grow rapidly under the condition of supplementing certain salts and aeration. The experimental results revealed that saline-alkali waters water could be purified in some extent by the algae. After 36 hours culturing, the eliminating rates of 8 main ions (Na+, K+, Ca2 +, Mg2 +, Cl-, SO2-4, HCO-3, CO2-3 ) in the water respectively reached 48. 5 %, 5.9%, 77.5%, 74.5%, 28.2%, 46.7%, 100%, 53. 1%.
