1簡介
1.1總則
本報告描述了蘇瓦瑙蘇里廢水處理廠Kinoya擴建第一階段的監(jiān)控戰(zhàn)略。第一階段施工設施包括：
■新建入口設施包括現(xiàn)有入口旁路的除砂設施和濾砂設施。
■附加(第3)主凈化器
■附加(第2) 厭氧污泥消化池和氣體處理設備。
2002年，Kinoya WWTP升級包括SBR廠下游入口設施。污水通過柵格后分別流入主凈化器和SBR處理廠。盡管在SBR處理廠中分離的污泥和污水返回主處理流程，SBR處理廠的電力、儀器操作和控制設備完全與主處理廠分開進行操作。
本報告僅限于論述主處理廠，不包括SBR廠，但是在二個區(qū)域之間的最小控制連接除外。特別是，本報告僅限于新建設施的控制或新建設施相關(guān)的控制，如入口設施、凈化器1&2、污泥泵和消化池的變更。
1.2概述
未處理的污水通過3條污水管流入Kinoya污水處理廠。東部區(qū)域和蘇瓦西部污水主干道和場地南方末端一起連通到砂井。提升泵站將混合的污水輸送到處理間，然后輸送到入口設施，該處理間位于場地頂端，和東部上部污水管連通，向處理廠入口處輸送污水。處理后的污水通過渠口流入大海。污泥塊經(jīng)過處理后可進行垃圾填埋。
1.3系統(tǒng)構(gòu)架
原主處理廠通常采用完全手工操作，在原先的升級中沒有進行變更。
無線SCADA（數(shù)據(jù)采集與監(jiān)控系統(tǒng)）安裝了SBR（序列間歇式活性污泥法）處理裝置，以便操作員通過HMI (人機界面)的一臺個人計算機進行操作，操作員可以在管理大樓的控制室，監(jiān)測和控制處理廠作業(yè)。SCADA（數(shù)據(jù)采集與監(jiān)控系統(tǒng)）通過設置在序列間歇式活性污泥法（SBR）裝置的室外配電柜上的PLC（控制面板）進行控制。
主處理廠的升級涉及PLC（控制面板）安裝，包括現(xiàn)有數(shù)據(jù)采集與監(jiān)控系統(tǒng)（SCADA）的升級。SCADA系統(tǒng)要求能夠?qū)⑻砑拥闹魈幚韽S信息提供給操作員進行處理。PLC（控制面板）安裝在新建的開關(guān)室里，位于再循環(huán)泵站旁。參見圖4532597-E005。
數(shù)據(jù)采集與監(jiān)控系統(tǒng)（SCADA）對處理廠車間輸入/輸出的控制必須與各個處理廠分開進行操作。 由于未來還將進行升級，在主處理廠所有新建設備將增加到新建PLC（控制面板）和數(shù)據(jù)采集與監(jiān)控系統(tǒng)（SCADA）上進行監(jiān)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.

Suva nousori Package 4 - Kmoya STP Upgrade
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.)
