This equipment can remove turbidness and decolor, lower CODcr, BOD5 and improve the biodegradability of wastewater, especially useful for decoloring and heavy metal removal.

广泛应用于电镀废水、印染废水、洗煤废水、制革废水、洗毛废水、造纸废水等各类废水的处理技术及水回用工程。该设备具有除浊脱色，降低CODcr、BOD5，提高废水的可生化性等作用，尤其对脱色及去除重金属效果更加显著。

Properties and applications of decolorizing agents, bleaching agents and whitener s are introduced.

The decolorizing effects of fresh MnO_2 on xylenol orange and methylene blue and the main factors influ- encing the decolorizing effects were studied.

研究了新生MnO_2对二甲酚橙和亚甲基蓝的脱色效果，考察了影响脱色效果的主要因素。

The decolorization rates of the 4 typical types of dye-stuff (500 mg/L)under the tests were all over 90%.

脱色剂对四种典型的染料的脱色率都接近90%。

First, removing protein by Sevage method. According to literature, it had best efficiency when polysaccharide liquid 2mg·mL~(-1) was treated with chloroform: n-butanol (3:1) and repeated for 3 times. Second, moving pigment with H_2O_2. In order to shorten the time and prevent the broken of structure of polysaccharide, the experiment was operated at 37℃. The following were dialyzation, concentration(60℃) and freeze-drying.

首先Sevage法除蛋白，根据文献，确定氯仿：正丁醇为3：1，多糖浓度2mg·mL~(-1)时，重复三次，除蛋白效果最佳；脱色采用了双氧水氧化法，为加快脱色时间，又要避免双氧水对多糖结构的破坏，实验在37℃下进行；透析、浓缩、干燥过程同样为了保证多糖结构的完整性和提取后物质疏松易溶解，先透析，然后60℃浓缩，最后是冷冻干燥。

Ccording to different current densities, the decolorization mechanism is specified into three processes as electrooxidation, electroreduction and adsorption.

CF对苋菜红的脱色机制因电流密度的不同，明显地分为电氧化、电还原和吸附脱色三种过程。

This effect was observed clearly at final concentration between 1 and 10μ mol/L after treating for 24 hours. We concluded that the possible mechanisms of hydroquinone bleaching hyperpigmented skin were through its inhibition of tyrosinase activity at lower concentration and its cytotoxicity at higher one.

提示18α-甘草酸双胺盐、熊果苷的皮肤脱色作用机制与氢醌可能不同，后者低浓度时以抑制酪酸酶活性为主，高浓度时主要是细胞毒，且细胞早期的损伤部位可能发生在树状突。18α-甘草酸双胺盐能否成为一种无细胞毒酪氨酸酶抑制型皮肤脱色剂有待进一步临床加以验证。

The factors,which infuences the decolorization effect of galactomannan extracted from the seeds of Trigonella Foenumgraecum were studied by ethanol refluxing.
