中文摘要：
分别用葸酮比色、苯酚-硫酸及气相色谱法3种测试方法测试了上海市某生活小区生活污水的糖类组成。试验结果表明，蒽酮比色法测试糖类浓度的准确性与精确性优于苯酚-硫酸法，但不能得出污水中糖类的详细组成情况；与蒽酮比色法和苯酚-硫酸法相比，气相色谱法不仅能得出污水中糖类的详细组成．而且还具有较高的精密度。气相色谱法测得的生活污水中各种单糖,如木糖、甘霸糖、葡萄糖、半乳糖、鼠李糖、核糖、岩藻糖的质量浓度分别为8．25、6．02、5．52、4．80、4．44、4．41、2．66mg／L。
英文摘要：
Sugars in a typical Shanghai domestic wastewater sample were measured by three methods： anthrone method, phenol sulfuric acid method and gas chromatography （GC） method. Both colorimetric methods were adequate for glucose measurements; the anthrone method was more precise and more accurate than the phenol sulfuric acid method in the sucrose recovery test runs. Although it took a rather long time to prepare the sample for GC analysis, the GC method was the only one capable of characterizing the sample＇s sugar content; xylose （8.25 mg/L）, mannose （6.02 mg/L）, glucose （5.52 mg/L）, galactose （4.80 mg/L）, rhamnose （4.44 mg/L）, ribose （4.41 mg/L）, and fucose （2.66 mg/L） were found in the sample. The GC method was also the most precise of the three methods.
