摘要： The invention concerns a method in a paper machine for arrangement of its water circulation. In view of full or partial closing of the water circulation in a paper machine, the wash waters from the fabrics and from other devices in the paper machine as well as the waters drained from the paper web to be produced are recovered selectively based on the place of origin of the waters. At least a part of said recovered different waters are cleaned, and the cleaned waters are recirculated to applications of reuse suitable in view of their washing potential in the paper-making process.

摘要： The invention concerns a method for arrangement of the water circulation in a paper mill, which paper mill comprises a pulp manufacturing plant provided with a water circulation system, such as a TMP plant, and a paper machine provided with a water circulation system. In the invention, in view of reducing the amount of fresh water supplied to the paper mill, a part of the amount of fresh water supplied to the paper mill is substituted by water or waters cleaned locally from waters contaminated at the paper mill. The concentrate or concentrates obtained from the stages of water cleaning is/are utilized where applicable by arranging said concentrate(s) to flow upstream in relation to the raw-material flow for reuse at the paper mill. By means of these operations the level of the amounts of interfering substances circulating in the paper mill is controlled.
摘要翻译：本发明涉及一种用于在造纸厂中布置水循环的方法，该造纸厂包括设置有水循环系统的纸浆制造厂，例如TMP设备，以及具有水循环系统的造纸机。在本发明中，考虑到减少供应给造纸厂的淡水量，供给到造纸厂的淡水量的一部分被水或在造纸厂污染的水中局部清洗的水所取代。在适用的情况下，通过将所述浓缩物相对于原料流在上游流动以在造纸厂再利用而在水处理阶段获得的浓缩物或浓缩物被利用。通过这些操作，控制在造纸厂循环的干扰物质的量的水平。
