亞什蘭水處理技術：工業設備的水循環和水處理的發展

Advances in Water Recycle and Treatment for Industrial Facilities

當前工業生產面臨的環境壓力越來越高，既要減少污水的排放總量，還要提高污水的排放標準。因此，必須將化學方法和非化學方法結合起來，才能取得良好的水處理效果。亞什蘭水技術開發出領先的腐蝕和沉積物控制方案，這些方案對環境的毒性極低，磷含量極低，應用于工業水系統中，可極大地提高冷卻水系統的循環倍數。另外，中等規模的工廠現在可以將生物氧化系統與膜系統和化學處理方法結合起來，以促進水的循環利用和再生使用。本文探討將化學處理方法和非化學處理方法有效結合起來以全面解決水系統問題，在實際應用的成功案例中，有的耗水量減少，有的利用生物反應器-膜的組合污水回用系統，耗水量低至5m3/h。

There is high and growing environmental pressure on industrial plants to reduce both the volume of water discharge as well as the level of contaminants discharged.  It is required to combine both chemical and non-chemical treatment methods of water treatment.  Ashland Water Technologies has developed highly advanced corrosion and deposit control formulations for industrial water systems that have very low environmental toxicity and phosphate levels - that allow maximum conservation of water in cooling systems.  In addition, medium size industrial operations can now combine biological oxidation systems with membrane systems with chemical water treatment to recycle and reuse water for process water applications.  This paper will discuss how combined chemical and non-chemical programs effectively take a total water system approach.  Specific case histories will discuss reduced water consumption, and combined bioreactor-membrane systems reuse of waste water for water flows as low as 5 cubic meters per hour.
