The wastewater from gum benzion production contains benzaldehyde, cyanide, gum benzoin and ethyl benzoate. When the cyanide is determined by isonicotinic acidpyrazalon method, the ethyl benzoate is distilled and goes into NaOH absorption liquid with cyanide in the process of predistillation, because its boiling point is low. Thus the absorption liquid produces a great deal of foam and feculence.

摘要］有机化工产品安息香生产废水中含有苯甲醛、氰化物、安息香和苯甲酸乙酯，在用异烟酸吡唑啉酮法对其进行氰化物测定时，由于油酯类的沸点较低，在预蒸馏过程中被蒸出和氰化物一起进入NaOH吸收液，使得吸收液产生大量泡沫和沉淀，严重干扰后续比色测定。

The watermelons, the citrullus lamtus or the stems and leaves thereof are taken as raw materials, and the extracting process comprises the following steps: firstly, the raw materials are washed clean and broken to separate the watermelon peel from the watermelon pulp for respectively extracting juice; the two juices are mixed, and micro-filtration and ultra-filtration are carried out to remove insoluble substances and macromolecular substances; and then reverse osmosis and nano-filtration are carried out to obtain the filtrate; the pH value of the filtrate is regulated and then a macroporous strong acid cation exchange resin column is added; and then ammonia water is taken as an eluant for isocratic elution; the eluent obtained is decompressed, distilled, deaminized, discolored, condensed and crystallized to obtain a white crystalline product of the natural L-citrulline extracted from the watermelons.

本发明方法以西瓜、打瓜或者其茎叶为原料，其过程为：首先将原料清洗干净，破碎后将西瓜皮西瓜瓤分开，分别进行榨汁；所得汁液合并，经过微滤和超滤除去不容物和大分子物质；然后再经反渗透和纳滤过滤；透过液调节pH值后通入大孔型强酸性阳离子交换树脂柱；然后以氨水做洗脱剂进行等度洗脱；将洗脱液减压蒸馏脱氨，脱色，浓缩结晶，得到西瓜提取天然L-瓜氨酸白色结晶产品。

Finally, the effect of the complete recycling use of distilled effluent on ethanol fermentation was examined in order to save the cost for the treatment of waste distillage and promote cleansing production. Based on the data of 13 circulations, although the average fermentation time needed to be extended to 30~40 hours, over 12.5% ethanol was achieved, at the same time, residual reducing sugar and total sugar were maintained below 0.70% and 0.90%, which indicates that the negative effect of the completely recycling use of waste distillage was limited, and the waste distillage can be completely recycled within the fermentation system.

在此基础上，从减轻废糟液处理负荷，实现清洁生产的需要出发，进行了无种子罐条件下酒精蒸馏废液直接全循环使用的自絮凝颗粒酵母酒精连续发酵实验研究，十三次全循环运行得到的实验数据，与无废液循环的实验结果相比，虽然平均发酵时间略增至30h～40h，但发酵终点酒精浓度仍达到12.5％以上，残还原糖和残总糖分别在0.70％和0.90％以下，说明循环积累物对发酵的影响有限，废糟液直接全循环使用的工艺技术路线可行。
