中化新网讯 近日，涪陵页岩气公司产出水处理站在绿色环保生产与资源循环利用方面取得新进展，处 理合格后的产出水成为站内"心脏设备"蒸汽锅炉和预处理段药剂配制水源，实现了从达标外排放到绿色 内循环的重要跨越。 据介绍，产出水处理站预处理段涵盖混凝沉淀池、氧化反应池等多环节，药剂配制需水量大且对水质要 求严苛。自来水含多种离子，与部分特定药剂配伍时可能发生微妙反应，影响药剂黏度、稳定性与抗剪 切性能。经深度处理的产出水离子组成更简单稳定，与常用药剂配伍性更优，能充分发挥药效，提升预 处理措施的成功率与有效性。 据了解，过去蒸汽锅炉使用自来水，硬度约150毫克/升，极易结垢，需额外投入工业盐进行软化，并频 繁添加阻垢剂和排污清洗，成本与风险双高。而现在用处理后的产出水，硬度远低于自来水，从源头极 大地抑制了水垢的生成，不仅保障了锅炉的平稳运行，而且减少了燃料与药品的消耗，综合效益显著。 在页岩气开采中，大量井底积液（产出水）随同气体产出，其处理难题备受行业关注。此前，涪陵页岩 气公司通过引进先进处理装置，处理后的水质达标排放。今年以来，该公司主动探索这些"合格水"的深 层价值。经过多轮技术攻关与试验，他们发现，这些水 ...
