自动化废水处理过程（中英文）

如何确保最终废水处理过程正常运行，并且流出物安全且可追溯？首先将 pH 值调整过程自动化。

pH 值高或低的废水被收集在泵提升站中，该泵提升站可以方便地放置在实验室站下方或地面以下。

然后，废水被泵送到批量 pH 调节系统，该系统使用连接到多参数控制器（GF Signet 9950 SmartPro 双通道变送器）的潜水式 pH 传感器（带 3-2724 电极的 GF Signet 2751-3 传感器）。

控制器有两个 4-20 mA 环路输出，可按比例驱动化学计量泵（Grundfos智能数字计量泵）。

超声波液位传感器（Flowline DL14 Echopod）监测处理罐液位，并向 9950 发出装满和空着的信号。9950 中的高级布尔逻辑功能允许将最多三个液位传感设备连接到一个继电器中。 3-9950-2 提供双通道多参数输入和两个 4-20 mA 输出。

为确保符合当地排放要求，请安装在线 pH 传感器 (GF Signet 2751-1) 以在废水进入下水道之前对其进行监测。在 9950 多参数变送器的帮助下，如果废水流 pH 值不符合要求，上游 Georg Fischer 驱动阀将关闭。

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 测量废水流量，并可将数字信号发送到 9950 进行总计。对于长期报告，可以从 9950 或直接从 2580 FlowtraMag 向楼宇自动化系统发送 4-20 mA 信号。

当当局提供最终的废水排放量，而不是根据用于运行其设施的输入清洁水向用户收费时，可以实现巨大的节省。

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!
