摘要
高压Ｍ废水成分较复杂，如何准确测定其中硫化物的含量，是考查高压Ｍ废水处理好坏的关键问题．本论文分析了测量误差产生的原因，选择了能使测量值趋于准确的新型预处理沉淀剂，并根据水中硫化物含量的不同，选用不同的测量方法，达到减少杂质干扰、准确分析、降低误差的目的．
The composition of the high-pressure wastewater M is very complicated, so how to mea sure the quantity of sulphide in high-pressure wastewater M disposal is the most important.This thesis analysed the cause of measuring deviation,selects a new style predisposing deposit which makes measuring more accurate,and selects various measuring method according to the contents of sulphide,so as to reduce impurity imterferences,reach a precise result and lower deviation.
