摘要： A method of treating chemical process water which contains dissolved solids, usually of a biodegradable organic nature. According to the invention, the dissolved organic solids, which are objectionable because they cause process equipment corrosion, undesirable product and process odors and pollution, are treated with ultraviolet light. The light treatment causes dissolved materials of relatively simple chemical structure to react and create more complex, less soluble materials which can easily be removed from the system as they become less soluble. The method is applicable to papermaking and numerous other industrial processes using large quantities of process water.

摘要： A method of treating papermaking white water which contains dissolved solids, usually of a biodegradable organic nature. According to the invention, the dissolved organic solids, which are objectionable because they cause process equipment corosion, undesirable product and process odors and water pollution, are treated with ultraviolet light so as to lower their concentration and eliminate these problems. The light treatment causes material of relatively simple chemical structure to polymerize into more complex, less soluble materials which can easily be removed from the system as they become less soluble. The method is applicable to papermaking and other industries process using large quantities of process water. The treatment cell, which preferably operates on clarified white water, may be placed in series with the process while water flow or in parallel therewith, and can be operated as a continuing treatment process or as a intermittent treatment process.

摘要翻译：一种处理造纸白水的方法，其含有溶解的固体，通常具有可生物降解的有机性质。根据本发明，由于它们引起工艺设备腐蚀，不良产物和工艺气味和水污染而令人不快的溶解有机固体用紫外线处理以降低其浓度并消除这些问题。光处理使得相对简单的化学结构的材料聚合成更复杂，较不易溶的材料，当它们变得较不溶解时，它们可以容易地从系统中除去。该方法适用于使用大量工艺用水的造纸等行业工艺。优选在澄清的白水上操作的处理池可以与过程白水流或与其平行放置，并且可以作为持续处理过程或间歇处理过程来操作。
