造纸废水处理pH值的异常波动成因

Causes of abnormal fluctuation of pH value in papermaking wastewater treatment

pH值的异常波动主要与生产现场排放的酸碱类物质有关。以大型造纸企业来说，酸碱废水主要来自对设备的定期清洗。

The abnormal fluctuation of pH value is mainly related to the acid and base substance discharged from the production site. For large paper-making enterprises, acid and alkali wastewater mainly comes from regular cleaning of equipment.

造纸废水处理进水水量 、水质异常分析

Abnormal analysis of influent water quantity and water quality in papermaking wastewater treatment

进水水量通常保持恒定 ，但是如果发生事故排水，生产线为了清洗槽体、设备等也会产生大量水洗水，如果是事故还会废弃大量原料和化学品，这样的废水流入废水处理场，往往会对系统造成比较大的冲击。这也是初沉池、生化池出水COD含量偏高的原因。

The water content usually remain constant, but if the accident drain, the production line for cleaning tank, equipment will produce a lot of washing water, if the accident will waste a lot of raw materials and chemicals, such as wastewater into the wastewater treatment field, often to the system caused by the larger impact. This is also the initial pool, biochemical pool effluent COD content is high.

由于废水中投入的原材料大多是纤维和直链淀粉，特别是直链淀粉分子量较大，物化沉淀性也不好，加之混杂的分散剂也影响了物化处理段PAC 和PAM的混凝效果。这些都是进流废水水量和水质对系统的影响。

Because the raw materials in the wastewater into most of the fiber and amylose amylose, especially large molecular weight, chemical precipitation is not good, and the mixed dispersant also affects the physicochemical treatment PAC and PAM coagulation effect. These are the effects of incoming wastewater, water quantity and water quality on the system.
