造纸污水处理产生源头
制浆、抄纸都排出大量废水。制浆产生的废水，污染最为严重。洗浆时排出废水呈黑褐色，称为黑水，黑水中污染物浓度很高，BOD高达5—40g/L，含有大量纤维、无机盐和色素。漂白工序排出的废水也含有大量的酸碱物质。抄纸机排出的废水，称为白水，其中含有大量纤维和在生产过程中添加的填料和胶料。2
Pulping and papermaking waste a lot of waste water. The wastewater produced by pulping is the most polluted. Wastewater discharged during pulp washing is black-brown, which is called black water. The concentration of pollutants in black water is very high. BOD is as high as 5-40g/L. It contains a lot of fibers, inorganic salts and pigments. Waste water from bleaching process also contains a lot of acid and alkali substances. The waste water discharged from paper machine is called white water, which contains a lot of fibers and fillers and adhesives added in the production process. Two
造纸行业是一个对环境污染较重的行业，制浆造纸生产工艺耗水量大，造纸污水水主要来自造纸工业生产中的制浆和抄纸两个生产过程。
Paper industry is a serious environmental pollution industry. The production process of pulping and papermaking consumes a lot of water. Paper sewage mainly comes from the two production processes of pulping and papermaking.
1、制浆是把植物原料中的纤维分离出来，制成浆料，漂白成浆;
1, pulping is the separation of fiber from plant material, making slurry, bleaching pulp.
2、抄纸是把浆料稀释、成型、压榨、烘干，抄制、加工成纸。
2, papermaking is to dilute, shape, press, dry, copy, and process pulp.
造纸污水处理工艺与废液资源化利用是解决整个造纸行业污染的关键。当今国家经济高速发展，环境保护的力度在不断加大，对重污染行业如制浆造纸、印染、电镀等严格实行总量控制政策，国家环保政策提倡清洁生产工艺和循环经济政策。
Papermaking wastewater treatment process and waste liquid utilization are the key to solve the pollution problem in the whole paper industry. Nowadays, with the rapid development of the national economy, the environmental protection is constantly increasing. The total amount control policy is strictly applied to heavy pollution industries such as pulp and paper making, printing and dyeing, electroplating, etc. The national environmental protection policy advocates clean production technology and circular economy policy.
