【摘要】 利用人工模拟的方法,在低温季节用金鱼藻等6种植物对养鱼池污水进行净化处理。结果表明,低温季节6种植物对TN、TP和硝态氮仍有较好的吸收效果,对氨态氮的吸收效果稍差;处理4～8天后能显著提高水体透明度,改善水质,但对改善COD和DO的效果不理想,可能与冬季温度低、植物换叶等因素有关。更多还原

【Abstract】 By the method of artificial imitation, in the low temperature season, 6 aquatic plants were used to decontaminate the polluted water. The results showed that the water plants could absorb total nitrogen, total phosphorus and saltpetre form nitrogen effectively, the ammonia nitrogen could also be absorbed but not so effective as the above three. After 4 to 8 days the transparency of water was improved greatly by the water plants but the COD and DO were not improved obviously. 更多还原
