Summary:The invention provides a sewage substrate improver which is prepared from the following steps: 1) pretreatment; 2) grafting; 3) amination; and 4) improver preparation. The substrate improver has very high adsorptivity for heavy metal ions and phenols, is capable of regulating the pH value of soil and fertilizing the soil after being added into the soil, and achieves the goal of improving the substrate. By using bagasse as the raw material, the sewage substrate improver is economical and cheap, is simple in operation steps, and can implement industrial production. The improver is massive, and can be recycled; and the adsorbed heavy metals can be reused in factory production after being eluted. 本发明提供种污水底质改良剂,由以下步骤制备:1)预处理;2)接枝;3)胺化;4)制备改良剂。有益效果为:制备的底质改良剂对重金属离子和苯酚的吸附率非常高,加入到土壤中还可以调节土壤pH值,肥化土壤,达到改良底质的目的;采用甘蔗渣为原料,经济廉价,且操作步骤简单,可工厂化生产;改良剂为块状,可回收再利用,吸附的重金属洗脱下来可重新用于工厂生产。
