Its principles as in the following chart: detectors for burglar alarm system is inside and outside the building in key areas, important places, protection, when the probe to illegal invaders, the signal transmitted to the alarm control: sound and light alarm, display address, about the person on duty after receiving the alarm, take measures according to the situation, to control the development of the situation. Antitheft alarm system alarm function in addition to the above, there is linkage function. Such as: open the alarm light (including infrared lamp), interactive audio and video matrix controller, switch on the alarm camera on the spot, matrix controller TV series of control: monitor displays an image, video footage, multimedia controller automatic or human ... the three guarantees period warranty 1, warranty 1) service period from date of acceptance of engineering, a 1year warranty, warranty processing is pleted within the response time is 48 hours. 2) service within the warranty period, we all accessories unconditional warranty for all equipment and replacement, all parts for all equipment (including all machine parts) maintenance and parts are free and provide onsite cleaning, test equipment services. During the warranty period, all equipment repair and maintenance services for onsite services, the resulting fees are waived. Free for system expansion, upgraderelated technical support services. 3) system warranty contact information to provide users with free technical advice, detailed answer to any problem in the system, to ask, answers will e detail. In the users if unable to solve the problems by themselves, directly by telephone, fax, Internet, letter, such as getting in touch with my pany (which calls for 24hour service), we will respond within 4 hours, consultation with users to solve the problem. 2, service response times, we are mitted to the warranty period on the operation of the system on a regular basis carry out prehensive inspections, found that the problem solving on the spot,目錄目 錄摘 要 IAbstract II目 錄 III第一章 設(shè)計(jì)概論 1 1 開發(fā)區(qū)自然條件: 1 設(shè)計(jì)水量與水質(zhì) 2第二章 工程概預(yù)算 4污水處理廠設(shè)計(jì)規(guī)模 4工程估算 4第三章 污水處理廠設(shè)計(jì) 6 污水處理廠址選擇 6 污水污泥處理工藝選擇 6 污泥處理工藝選擇 6 13 進(jìn)水泵房 13 細(xì)格柵和沉砂池 13: 14 A2/O池 14 鼓風(fēng)機(jī)房 15 配水集泥井 15 污泥濃縮池 15 脫水車間 16第四章 勞動(dòng)定員及其附屬構(gòu)筑物 17 17 17 18 18 18第五章 格柵的計(jì)算 20 20 20 22第六章 沉砂池的設(shè)計(jì)計(jì)算 26第七章 初次沉淀池的設(shè)計(jì)計(jì)算 28 28(為輻流式) 28第八章 A2/O反應(yīng)池的設(shè)計(jì)計(jì)算 36 36 36第九章 曝氣池的設(shè)計(jì)計(jì)算 42 42 42第十章 二沉池的設(shè)計(jì)計(jì)算 46 46 46第十一章 清水池的設(shè)計(jì)計(jì)算 48第十二章 濃縮池的設(shè)計(jì)計(jì)算 49 49 49第十三章 消化池的設(shè)計(jì)計(jì)算 51 51 51第十四章 污水處理廠總體布置 58 58 58 污水處理廠的平面布置 60 61 61 62 污水處理部分高程計(jì)算 63 污泥處理部分搞程計(jì)算 65結(jié) 論 67參考文獻(xiàn) 錯(cuò)誤!未定義書簽。該污水處理廠工程,規(guī)模為15萬噸/日。s site to see and listen to the leadership proposal, and in accordance with the actual needs of the project, with reference to the relevant international standards and national standards, bined with the experience accumulated by the pany engaged in multiple projects, prepare the technology package.
