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。

It is concluded that the ultrafiltration preconcentration combining with multieffect evaporation is a promising concentration procedure for straw black liquor, which can not only reduce the concentration costs, but also improve the subsequent evaporation and combustion operation due to the desilicification and purification of ultrafiltration.

两种膜比较，磺化聚砜膜更易清洗，而且水通量大。5）超滤浓缩后，黑液中木素的浓度和纯度大大提高，超滤是从黑液中分离木素的理想方法。6）与多效蒸发相比，用超滤法浓缩麦草黑液可降低能耗70~85%，若用于黑液的预浓缩，再结合多效蒸发，不仅可以降低黑液的浓缩费用，而且由于除硅和纯化作用，会大大改善后继的蒸发和燃烧的操作。

Then the higher filtration intensity, productive capacity and the phosphorus recovery are obtained for the employment of filter aid in the filtration systems of the above-mentioned 2 sets of phosphoric acid facilities with dihydrated phosphogypsum process and 1 set with the dihydrated phosphogypsum section of semi-dihydrated phosphogypsum process, except the semi-hydrated phosphogypsum section.

云南红磷化工有限责任公司有3套磷酸装置，其二水磷酸过滤系统运行状况较差，除1套半水-二水磷酸装置在半水过滤系统不能使用助滤剂外，其它二水过滤系统使用助滤剂后，装置过滤强度，生产能力，磷收率均有较大提高，助滤剂年费用仅24万元，但增加产量的经济效益上千万元。
