1简介
1.1总则
本报告描述了苏瓦瑙苏里废水处理厂Kinoya扩建第一阶段的监控战略。第一阶段施工设施包括：
■新建入口设施包括现有入口旁路的除砂设施和滤砂设施。
■附加(第3)主净化器
■附加(第2) 厌氧污泥消化池和气体处理设备。
2002年，Kinoya WWTP升级包括SBR厂下游入口设施。污水通过栅格后分别流入主净化器和SBR处理厂。尽管在SBR处理厂中分离的污泥和污水返回主处理流程，SBR处理厂的电力、仪器操作和控制设备完全与主处理厂分开进行操作。
本报告仅限于论述主处理厂，不包括SBR厂，但是在二个区域之间的最小控制连接除外。特别是，本报告仅限于新建设施的控制或新建设施相关的控制，如入口设施、净化器1&2、污泥泵和消化池的变更。
1.2概述
未处理的污水通过3条污水管流入Kinoya污水处理厂。东部区域和苏瓦西部污水主干道和场地南方末端一起连通到砂井。提升泵站将混合的污水输送到处理间，然后输送到入口设施，该处理间位于场地顶端，和东部上部污水管连通，向处理厂入口处输送污水。处理后的污水通过渠口流入大海。污泥块经过处理后可进行垃圾填埋。
1.3系统构架
原主处理厂通常采用完全手工操作，在原先的升级中没有进行变更。
无线SCADA（数据采集与监控系统）安装了SBR（序列间歇式活性污泥法）处理装置，以便操作员通过HMI (人机界面)的一台个人计算机进行操作，操作员可以在管理大楼的控制室，监测和控制处理厂作业。SCADA（数据采集与监控系统）通过设置在序列间歇式活性污泥法（SBR）装置的室外配电柜上的PLC（控制面板）进行控制。
主处理厂的升级涉及PLC（控制面板）安装，包括现有数据采集与监控系统（SCADA）的升级。SCADA系统要求能够将添加的主处理厂信息提供给操作员进行处理。PLC（控制面板）安装在新建的开关室里，位于再循环泵站旁。参见图4532597-E005。
数据采集与监控系统（SCADA）对处理厂车间输入/输出的控制必须与各个处理厂分开进行操作。 由于未来还将进行升级，在主处理厂所有新建设备将增加到新建PLC（控制面板）和数据采集与监控系统（SCADA）上进行监控。

Suva nausori Package 4 - Kinoya STP Upgrade
1 Introduction
1.1 General
This report describes the control strategy of the Stage 1 augmentation of the Kinoya Wastewater Treatment Plant in Suva Nausori. The Stage 1 works consist of
■ New inlet works including grit removal and screens to bypass existing inlet works.
■ Additional (3rd) primary clarifier
■ Additional (2nd) anaerobic sludge digester and gas handling equipment.
In 2002, tlie Kinoya WWTP was upgraded to include an SBR Plant downstream of the Inlet Works. The screened influent flow is now split between the Primary Clarifiers and die SBR Plant. Although and tlie sludge and effluent separated in the SBR Plant are returned to die Main Treatment Process, tlie SBR Plant is completely separate to the Main Treatment Plant in terms of electrical, instrumentation and controls.
This report will only focus on tlie Main Treatment Plant, and excludes die SBR Plant other dian the minimum control required to interface between die two areas. In particular diis report will only cover control of new works or control relating to new works eg changes to Inlet Works, Clarifiers 1&2, Sludge Pumping and Digesters.
1.2 Overview
Raw sewage enters die Kinoya Sewage Treatment Plant via 3 sewers. The Lower Eastern and Main Western Trunk Suva sewers join togedier in a manhole at die soutiiern end of tiie site and the Lift Pump Station transfers die combined sewage to a chamber tiiat feeds die Inlet Works at the top of the site, which joins the Upper Eastern Sewer feed into die plant. The treated effluent is discharged via an outfall to tiie sea. Sludge-cake removed by the treatment process is taken to landfill.
1.3 System Architecture
The original Main Treatment Plant has always been operated completely manually, and this has not changed with previous upgrades.
A wireless SCADA system was installed witii tlie SBR Plant installation so that the operator could monitor and control die plant from an HMI (Human Machine Interface) on a PC in a control room in the administration building. The SCADA system controls the plant via a PLC located in outdoor cabinets alongside the SBR plant.
This upgrade to the Main Treatment Plant involves a similar PLC installation along with an upgrade to die existing SCADA system to incorporate tlie additional Main Treatment Plant information necessary for operator control. The PLC is to be installed in die New Switchroom next to die Recirculation Pump Station. Refer Drawing 4532597-E005
The control from die SCADA system to die plant field I/O will be separate for each plant. As future upgrades are carried out, all new equipment in die Main Treatment Plant will be added to the new PLC and SCADA system for monitoring and control.

1.4 Control Strategy
All new pumps and motors installed in the Main Treatment Plant as part of this upgrade will be controlled by PLC, with additional backup hardwired interlocks in case of PLC failure.
Level instruments providing interlocking signals will have backup probes to provide the hardwired interlocks in case of instrument failure.
Indications will be provided to the operator displays for all new pumps and instrumentation as well as the existing Raw Sludge Pumps and valves upstream and downstream of automatically starting pumps.
1.5 Electrical
The existing substation by the Main Lift Pump Station currentiy supplies the Main Treatment Plant and it is assumed in this report that it will be adequate to supply all new pumps, control and associated with this Stage 1 upgrade. (The Main switchboard will be relocated to the New Switchroom.)
