色度法

Another remarkable characteristic of printing and dye the waste water is that the colour is high, is it adopt biological carbon pool is it is it deal with to decolour to go on to it , for activated carbon absorbent spent to design originally, active charcoal adsorption method to utilize porous active charcoal material make one or many kinds of material of waste water it absorbs to be that surface get rid of in active charcoal.

印染废水的另一显著特点就是色度高，本设计采用生物碳池对其进行脱色处理，所用的吸附剂为活性碳，活性炭吸附法就是利用多孔活性炭物质使废水中的一种或者多种物质被吸附在活性炭表面而去除的。

The results indicate that the p retreatment process can improve biodegradability of the wastewater and reduce COD and colority,result

文摘：采用铁屑过滤法预处理可生化性差的印染废水，能改善废水的可生化性，降低废水的COD和色度，有利于后续生化处理。

The absorbance at 630nm is the index of transmittancy of pectin solution. The yield of pectin can be converted by absorbance of pectin solution by the method of carbazole colorimetric at 530nm.

以630nm吸光度作为果胶溶液色度的指标；采用咔唑硫酸比色法，在530nm时测定果胶液的吸光度计算溶液中果胶得率。

The results were very successful.The removal rates of chromaticity and CODCr reached 96.56% and 94.46% respectively under the optimal conditions as follows:dosages of H2O2 and Fe2+ were 4.0g/L and 0.3 g/L respectively,microwave irradiation power was 500 W,and radiation time was 1 min.The investigation shows that the microwave irradiation,homogeneous Fenton oxid...

结果表明，微波-Fenton氧化-PASS混凝法适合于处理复杂垃圾渗滤液，在H2O2的质量浓度为4.0 g/L，Fe2+质量浓度为0.25 g/L，pH值为3.0，固定微波辐射功率500 W，辐照1 min，PASS质量浓度为25 mg/L的最佳条件下，出水色度仅15倍，脱色率和CODcr去除率分别达到96.86%和94.46%；微波辐射、Fenton氧化和PASS混凝沉淀结合处理垃圾渗滤液废水时具有较好的协同效应。
