摘要
Abstract
The effects of different zeolite powder dosage ratio on sludge dewatering,sedimentation,drying time,dry weight of plant roots in the ecological beds were studied,and the zeolite powder dosage ratio of 6% was chosen.The concentrations of nitrogen and phosphorus of sludge in the ecological bed were measured,and the results show that total phosphorus content decreased 13.2% and 12.2%;total nitrogen content decreased 48.3% and 49.2%;nitrate nitrogen content decreased 67.2% and 70.2%,respectively in the yellow iris beds and reed beds.关键词
