【摘要】：隨著經(jīng)濟(jì)的不斷發(fā)展,水資源已經(jīng)成為制約我國經(jīng)濟(jì)社會可持續(xù)發(fā)展的重要因素,造成我國嚴(yán)峻水環(huán)境形勢的原因主要包括三個方面：水資源短缺、水污染嚴(yán)重、浪費(fèi)驚人。在生活質(zhì)量越來越被重視的今天,城市水污染治理是一個刻不容緩的問題。根據(jù)經(jīng)濟(jì)發(fā)展的需要,全國各地相繼建成各種各樣的污水處理廠,但在實(shí)際運(yùn)行中,其自動化程度并不高,而且運(yùn)行效果不佳。Sequencing Batch Reactor (SBR)為序列間歇式活性污泥法,又稱作序批式活性污泥法,是一種污廢水生物處理技術(shù)。它是按時(shí)序來以間歇曝氣方式運(yùn)行,改變活性污泥生長環(huán)境的,被全球廣泛認(rèn)同和采用的污水處理技術(shù)。由于SBR污水處理工藝獨(dú)具的時(shí)序特性,使得它能夠采用自動控制技術(shù)來提高其運(yùn)行效率。目前國內(nèi)的SBR污水處理工藝計(jì)算機(jī)自動控制技術(shù)大部分都是僅對工藝過程進(jìn)行的流程自動控制,不能夠很好的確保出水水質(zhì)。本文根據(jù)SBR污水處理工藝過程的發(fā)展及國內(nèi)外污水處理過程自動控制現(xiàn)狀的分析研究,在對SBR污水處理工藝流程進(jìn)行全自動控制的基礎(chǔ)上,利用西門子組態(tài)軟件Wincc建立組態(tài)界面,使得監(jiān)控PC機(jī)能夠更加清楚的展現(xiàn)出現(xiàn)場狀況,并利用PROFIBUS進(jìn)行通訊實(shí)現(xiàn)PLC現(xiàn)場控制設(shè)備與控制室PC機(jī)之間的信息傳輸,最終達(dá)到控制室對現(xiàn)場設(shè)備的全自動控制及現(xiàn)場開關(guān)對設(shè)備的手動控制,對現(xiàn)場的實(shí)時(shí)數(shù)據(jù)和歷史數(shù)據(jù)進(jìn)行監(jiān)控與記錄,組態(tài)界面能夠清晰明了的顯示出現(xiàn)場情況,不僅使得對整個系統(tǒng)的控制更加靈活,而且可以確保系統(tǒng)工作的可靠性與準(zhǔn)確性。
[Abstract]:With the continuous development of economy, water resources have become an important factor restricting the sustainable development of our country's economy and society. The reasons for the severe water environment situation in China mainly include three aspects: water shortage, serious water pollution and astonishing waste. Nowadays, more and more attention has been paid to the quality of life, urban water pollution control is an urgent problem. According to the need of economic development, all kinds of sewage treatment plants have been built all over the country, but in actual operation, the degree of automation is not high, and the operation effect is not good. Sequencing Batch Reactor (SBR) is sequential batch activated sludge process. It is also called sequencing batch activated sludge process, which is a kind of wastewater biological treatment technology. It operates in intermittent aeration mode according to time series and changes the growth environment of activated sludge. It is widely recognized and adopted in the world. Because of the unique timing characteristics of SBR sewage treatment process, it can use automatic control technology to improve its operation efficiency. At present, the computer automatic control technology of SBR wastewater treatment process is mostly automatic control of the process, which can not ensure the quality of effluent. According to the development of SBR wastewater treatment process and the analysis and research of domestic and foreign wastewater treatment process automatic control status, this paper carries out automatic control of SBR sewage treatment process. The configuration interface is set up by using Siemens configuration software Wincc, which makes the monitoring PC machine more clearly show the field situation, and realizes the information transmission between the PLC field control equipment and the control room PC machine by using PROFIBUS communication. Finally, the automatic control of the field equipment in the control room and the manual control of the equipment on the spot switch are achieved. The real-time data and historical data of the field are monitored and recorded. The configuration interface can clearly show the situation of the field. It not only makes the control of the whole system more flexible, but also ensures the reliability and accuracy of the system.
