自動(dòng)化廢水處理過程（中英文）
如何確保最終廢水處理過程正常運(yùn)行，并且流出物安全且可追溯？首先將 pH 值調(diào)整過程自動(dòng)化。
pH 值高或低的廢水被收集在泵提升站中，該泵提升站可以方便地放置在實(shí)驗(yàn)室站下方或地面以下。
然后，廢水被泵送到批量 pH 調(diào)節(jié)系統(tǒng)，該系統(tǒng)使用連接到多參數(shù)控制器（GF Signet 9950 SmartPro 雙通道變送器）的潛水式 pH 傳感器（帶 3-2724 電極的 GF Signet 2751-3 傳感器）。
控制器有兩個(gè) 4-20 mA 環(huán)路輸出，可按比例驅(qū)動(dòng)化學(xué)計(jì)量泵（Grundfos智能數(shù)字計(jì)量泵）。
超聲波液位傳感器（Flowline DL14 Echopod）監(jiān)測(cè)處理罐液位，并向 9950 發(fā)出裝滿和空著的信號(hào)。9950 中的高級(jí)布爾邏輯功能允許將最多三個(gè)液位傳感設(shè)備連接到一個(gè)繼電器中。 3-9950-2 提供雙通道多參數(shù)輸入和兩個(gè) 4-20 mA 輸出。
為確保符合當(dāng)?shù)嘏欧乓?，?qǐng)安裝在線 pH 傳感器 (GF Signet 2751-1) 以在廢水進(jìn)入下水道之前對(duì)其進(jìn)行監(jiān)測(cè)。在 9950 多參數(shù)變送器的幫助下，如果廢水流 pH 值不符合要求，上游 Georg Fischer 驅(qū)動(dòng)閥將關(guān)閉。
How do you ensure your final wastewater treatment process is working properly and the effluent stream is safe and accounted for? Start by automating your pH adjustment process.
Wastewater streams with high or low pH values are collected in a Pump Lift Station that can be conveniently placed under lab stations or below floor level.
The waste stream is then pumped to a Batch pH Adjustment System, which uses a submersible pH sensor (GF Signet 2751-3 sensor with 3-2724 electrode) connected to a multi-parameter controller (GF Signet 9950 SmartPro dual-channel transmitter).
There are two 4-20 mA loop outputs from the controller that will proportionally drive your chemical metering pumps (Grundfos Smart Digital Dosing).
An Ultrasonic Level Sensor (Flowline DL14 Echopod) monitors treatment tank liquid levels and signals the 9950 for fill and empty conditions. Advanced Boolean Logic Function in the 9950 allows up to three level sensing devices to be tied into one relay. The 3-9950-2 provides two-channel multi-parameter inputs and two 4-20 mA outputs.
To ensure compliance with local discharge requirements, install an in-line pH sensor (GF Signet 2751-1) to monitor the effluent before it goes to the sewer. With the help of the 9950 multi-parameter transmitters, the upstream Georg Fischer actuated valve will close if effluent stream pH levels are not in compliance.
使用 GF 2580 FlowtraMag 測(cè)量廢水流量，并可將數(shù)字信號(hào)發(fā)送到 9950 進(jìn)行總計(jì)。對(duì)于長(zhǎng)期報(bào)告，可以從 9950 或直接從 2580 FlowtraMag 向樓宇自動(dòng)化系統(tǒng)發(fā)送 4-20 mA 信號(hào)。
當(dāng)當(dāng)局提供最終的廢水排放量，而不是根據(jù)用于運(yùn)行其設(shè)施的輸入清潔水向用戶收費(fèi)時(shí)，可以實(shí)現(xiàn)巨大的節(jié)省。
Effluent flow is measured with the GF 2580 FlowtraMag and a digital signal can be sent to the 9950 for totalization. For long-term reporting, a 4-20 mA signal can be sent to the building automation system from either the 9950 or directly from the 2580 FlowtraMag.
Big savings can be realized when authorities are provided final outgoing wastewater numbers instead of charging users based on incoming clean water used to run their facility!
