摘要
对高层建筑给水工程,在满足相同技术功能的条件下,可有多种类不同的方案。择优则必须通过技术经济计算比较,而一般的“优劣顺序标度”或“定基比率标度”的比较,尚欠完备。本文按有代表性的五种方案,探求用于定量经济分析计算的公式,最后用表格汇总,展现了明确的经济比较的通式系列。
A parallel experimental study has been carried out on biofilters with shield-shaped fibrous and semi-soft media. The experimental result has shown that,under the same efficiency requlrement(COD removal>90%),the loading rate for shield-shaped fibrous medium can be as high as 7 kg COD/m3 . d,greater than the loading rate for semi-soft media. It is concluded that,the shield-shaped filbrous medium is a new kind biofilter packing with economical,highly efficient and good biochemically treating properties.
