Purification of Water of Wastewater Pond by Wolffia arrhiza
摘要
Abstract
From April to September in 2009, the water purification in wastewater pond (2 500 m3 area, 1. 5 m depth) at Xinyang countryside was studied by use of Wolffia arrhiza as treating agent. The amount of Wolffia arrhiza used at beginning stage is 4 × 106个 · m-2(8.9 g · m-2 dry weigh). It was found that the declined values of pH,TP, TN,BOD5 and COD in the wastwater pond are 2.4,84.3% ,46.1%,76.9% and 69. 1% after 150 days treatment,respectively. The results showed that the water quality of wastewater pond can be improved significantly by Wolffia arrhir za.关键词
