摘要： Lignin and alkali are efficiently sorted out of alkaline black liquor discharged from the paper manufacturing/pulp and paper manufacturing industries and the treated water is made as purified water.Acid is added to the black liquor and its pH is adjusted to 2.5 to 3.5. An aggregating agent is added to have lignin contained in the black liquor settled and the black liquor is separated into lignin and clean water. Ozone gas, preferably in the micro bubble state, is given to the clean water for contact reaction.

摘要： Lignin is flocculated and batched off from a sulfide-free black liquor discharged out of a pulp digestion step by water disposal techniques, and organic matters remaining in the filtrate are removed to recover water, acids and caustic soda.A mineral acid and, if necessary, diluting water is added to the black liquor to control its pH to 1 to 7, and a flocculant is added to the black liquor to filtrate out flocculating lignin. Further, ozone is brought into contact with the filtrate to oxidize and break down organic matters in the filtrate and remaining organic matters are adsorbed onto activate charcoal for removal.
摘要翻译：木质素被絮凝，并通过水处理技术从纸浆消解步骤排出的无硫化物黑液中分离出来，并除去残留在滤液中的有机物质以回收水，酸和苛性钠。将黑色液体中的无机酸和必要时的稀释水加入到黑液中以将其pH调节至1至7，向黑液中加入絮凝剂以滤出絮凝木质素。此外，使臭氧与滤液接触以氧化和分解滤液中的有机物，并将剩余的有机物质吸附到活性炭上以除去。

摘要： A pulp production process can produce pulp at high yield without using sodium sulfide and high-temperature/high-pressure conditions if compared with the Kraft process and also collect lignin. Pulp is produced by processing wood chips for hydrophlicization at room temperature, using a dilute caustic soda aqueous solution, selectively partially modifying lignin in dilute nitric acid and digesting the wood chips by means of a dilute caustic soda aqueous solution under the atmospheric pressure. Lignin is agglomerated and sorted out from the isolated black liquor.
摘要翻译：如果与硫酸盐法相比，纸浆生产过程可以高产率地生产纸浆，而不使用硫化钠和高温/高压条件，并且还收集木质素。纸浆通过在室温下处理木屑进行亲水化处理，使用稀苛性钠水溶液，在稀硝酸中选择性地部分改性木质素，并在大气压下用稀碱苛性钠水溶液消化木片。木质素被聚集并从分离的黑液中分选出来。
