應用實績 : Hach 於法國污水處理廠進水毒性之監測方案
Monitoring Solution for Influent Toxicity Helps Protect the Wastewater Treatment
Background 背景介紹
The customer is a chemical plant in the south-east of France. Products are mostly vitamins, antioxidants and pigments for nutritional products, animal feed, cosmetics and pharmaceutical. The company’s own treatment plant takes care of the wastewater streams coming from the different production lines

客戶是一家位於法國東南部的化學廠。其製造產品主要是維他命(保健產品) 、用於營養品的抗氧化劑和色素、動物飼料、化妝品以及製藥。此公司自己的污水處理廠處理來自不同生產線的污水。
Potential sources of influent Toxicity are 潛在的進水毒性來源 :
Potential sources of influent Toxicity are 潛在的進水毒性來源 :
- Product discharge 產品排放水
- Clean In Place (CIP) processes 就地清潔（CIP）程序
- High salt concentrations 高鹽濃度
The EZ Toxicity analyzer uses respirometry to quickly and efficiently asses the effect of wastewater influent on the metabolic condition of the microorganisms in the activated sludge.
Hach EZ7900 水中毒性分析儀使用呼吸測定法快速有效地監測了廢污水對活性污泥中微生物代謝狀況的影響。
Challenge 挑戰
Early warning system with acute Toxicity alert to protect the activated sludge in the wastewater treatment plant against irreversible damage.
具有急性毒性警示的早期預警系統，可保護避免污水處理廠中的活性污泥受到不可逆轉的損害。
Problem 問題與需求
The customer required a complete single source plug and play integrated system including online analyzer / analyzer housing / preconditioning / commissioning and training to achieve real time online analysis of toxicity in the influent of his wastewater treatment plant. Influent toxicity represents a major risk (inhibition of wastewater biology) to the efficiency of biological treatment plants and can lead to permanent damage.

客戶需要一個整合式監測站，包括線上分析儀 / 分析儀防護箱 / 預處理 / 調試和培訓，以達到其污水處理廠進水毒性的即時線上分析。進水毒性代表著影響生物處理廠效率的主要風險（抑制污水生物），並可能導致永久性損害。
Benefits 方案效益
The addition of the Hach online monitoring technology with an EZ7900 Toxicity analyzer helped protect the wastewater treatment plant’s biomass from toxic substances in the influent. The risk of process failure and resulting discharge compliance violations was mitigated. The analytical shelter enabled the customer to install the analyzer independent of existing buildings at the optimum sampling point.
