廢水處理設備的材質選擇與安裝規范直接影響其處理效率、使用壽命及運行安全性，需結合廢水性質（如酸堿度、污染物成分）、處理工藝及使用環境綜合考量。合理的材質搭配能降低設備腐蝕風險，科學的安裝流程可保障系統穩定運行，兩者共同構成廢水處理系統有效發揮作用的基礎。

　　The material selection and installation specifications of wastewater treatment equipment directly affect its treatment efficiency, service life, and operational safety. It is necessary to comprehensively consider the properties of wastewater (such as acidity and alkalinity, pollutant composition), treatment process, and usage environment. A reasonable material combination can reduce the risk of equipment corrosion, and a scientific installation process can ensure the stable operation of the system. The two together form the foundation for the effective functioning of the wastewater treatment system.

　　廢水處理設備的材質需根據廢水腐蝕性、溫度及雜質特性針對性選用。不銹鋼是應用廣泛的基礎材質，憑借良好的耐腐蝕性適用于處理中性或弱酸堿廢水，常見于格柵、反應池內壁及管道等部件，其表面光滑特性可減少雜質附著，便于清潔維護。對于強酸堿廢水（如電鍍、化工行業排放的廢水），則需采用玻璃鋼材質，這種由樹脂與玻璃纖維復合而成的材料，耐化學腐蝕性能優異，且重量輕、易加工，適合制作沉淀池、過濾罐等大型構件。碳鋼常用于設備框架、支撐結構等非接觸廢水的部位，為增強其耐腐蝕性，通常會做防腐涂層處理（如涂刷環氧樹脂），但需定期檢查涂層完整性，避免銹蝕影響結構強度。此外，部分特殊處理環節會用到專用材質，如膜過濾組件多采用聚酰胺、陶瓷等，耐污染且截留精度高；曝氣裝置常用乙丙橡膠，柔韌性好且不易被氧化。

　　The material of wastewater treatment equipment should be selected according to the corrosiveness, temperature, and impurity characteristics of the wastewater. Stainless steel is a widely used basic material that is suitable for treating neutral or weak acidic and alkaline wastewater due to its good corrosion resistance. It is commonly used in components such as grilles, reaction tank walls, and pipelines. Its smooth surface can reduce impurity adhesion and facilitate cleaning and maintenance. For strong acidic and alkaline wastewater (such as wastewater discharged from electroplating and chemical industries), fiberglass material is required. This material is composed of resin and glass fiber composite, with excellent chemical corrosion resistance, light weight, and easy processing, suitable for making large components such as sedimentation tanks and filtration tanks. Carbon steel is commonly used in equipment frames, support structures, and other areas that do not come into contact with wastewater. To enhance its corrosion resistance, it is usually treated with anti-corrosion coatings (such as applying epoxy resin), but the integrity of the coating needs to be checked regularly to avoid corrosion affecting the structural strength. In addition, some special processing steps may use specialized materials, such as polyamide and ceramics used in membrane filtration components, which are resistant to pollution and have high retention accuracy; Ethylene propylene rubber is commonly used in aeration devices, which has good flexibility and is not easily oxidized.

　　設備安裝前的準備工作是保障后續運行的關鍵，需從場地、基礎及配套設施多方面規劃。場地選擇需滿足設備運行與維護空間需求，地面需平整堅實，避免低洼積水（可做硬化處理并設置排水坡度），同時遠離生活區與敏感區域，減少異味、噪音對環境的影響。基礎施工需根據設備重量與震動特性設計，大型設備（如沉淀池、壓濾機）需澆筑混凝土基礎，預埋連接件確保設備固定牢固，小型設備可放置在型鋼支架上，但需保證水平度（誤差控制在規范范圍內）。配套設施需提前布局，包括進水管道（材質與設備接口匹配，避免滲漏）、供電線路（按設備功率配置，做好防水、防觸電保護）、排水系統（預留檢修排水口，與市政管網連接順暢），同時預留足夠的操作通道與檢修空間，方便后期設備維護與部件更換。

　　The preparation work before equipment installation is the key to ensuring subsequent operation, and it needs to be planned from multiple aspects such as site, foundation, and supporting facilities. The site selection should meet the space requirements for equipment operation and maintenance. The ground should be flat and solid, avoiding low-lying water accumulation (hardening treatment can be done and drainage slopes should be set). At the same time, it should be far away from living areas and sensitive areas to reduce the impact of odors and noise on the environment. Basic construction needs to be designed according to the weight and vibration characteristics of the equipment. Large equipment (such as sedimentation tanks and filter presses) need to be poured with concrete foundations and pre embedded connectors to ensure that the equipment is firmly fixed. Small equipment can be placed on steel supports, but the levelness needs to be ensured (with errors controlled within the specified range). Supporting facilities need to be laid out in advance, including inlet pipes (matched with equipment interfaces to avoid leakage), power supply lines (configured according to equipment power, with waterproof and anti electric shock protection), drainage systems (reserved for maintenance drainage outlets, smoothly connected to municipal pipeline networks), and sufficient operating channels and maintenance space to facilitate later equipment maintenance and component replacement.

　　安裝過程中的技術規范直接影響設備性能發揮，需注重密封性、協調性與安全性。管道連接需保證密封嚴實，法蘭接口處需墊好密封墊片（根據介質選擇耐油、耐酸堿類型），螺紋連接需纏繞生料帶，避免因滲漏導致廢水外溢或處理效率下降。設備組裝需按工藝流程順序進行，如格柵、調節池、生化池、沉淀池的安裝需保證水流方向順暢，各單元銜接處的液位差符合設計要求，避免出現死水區域。電氣設備安裝需嚴格遵循電氣規范，接線牢固且做好標識，控制柜與設備間的線纜需穿管保護，接地可靠（接地電阻符合標準），防止短路、漏電等安全事故。對于需要現場焊接的部件，焊接質量需達標（如焊縫平整、無氣孔），焊接后及時做防腐處理，尤其在潮濕環境中需加強防銹措施。

　　The technical specifications during the installation process directly affect the performance of the equipment, and attention should be paid to sealing, coordination, and safety. The pipeline connection needs to be tightly sealed, and sealing gaskets should be placed at the flange interface (choose oil resistant or acid alkali resistant types according to the medium). Threaded connections need to be wrapped with raw material tape to avoid wastewater overflow or decreased treatment efficiency due to leakage. The equipment assembly needs to be carried out in the order of the process flow, such as the installation of grilles, regulating tanks, biochemical tanks, and sedimentation tanks, which should ensure smooth water flow direction, and the liquid level difference at the connection of each unit should meet the design requirements to avoid stagnant water areas. The installation of electrical equipment must strictly follow electrical specifications, with firm wiring and proper labeling. The cables between the control cabinet and the equipment must be protected by conduit, and the grounding must be reliable (with grounding resistance meeting standards) to prevent safety accidents such as short circuits and leakage. For components that require on-site welding, the welding quality must meet the standard (such as smooth welds and no porosity), and anti-corrosion treatment should be carried out in a timely manner after welding, especially in humid environments where rust prevention measures need to be strengthened.

　　安裝后的調試與驗收是確保設備正常運行的最后環節，需逐項檢查并優化。通水調試前先進行單機試運行，檢查泵、風機、攪拌器等設備的運轉狀況（如有無異響、振動是否過大），確認轉向正確、參數達標。通水后測試各處理單元的協同效果，如調節池的水質均化能力、生化池的曝氣均勻性、沉淀池的泥水分離效果，根據實測數據調整運行參數（如曝氣量、攪拌強度）。安全驗收需重點檢查防護設施，如設備防護罩是否安裝到位、緊急停車按鈕是否靈敏、危險區域警示標識是否清晰，同時驗證應急預案的可行性（如停電時的應急排水措施）。調試合格后，需整理安裝記錄、設備參數等資料存檔，為后期運維提供參考依據。

　　The debugging and acceptance after installation are the final steps to ensure the normal operation of the equipment, which need to be checked and optimized item by item. Before conducting water commissioning, conduct a single machine trial run to check the operation status of equipment such as pumps, fans, and mixers (if there is no abnormal noise or excessive vibration), and confirm that the steering is correct and the parameters meet the standards. After water supply, test the synergistic effect of each treatment unit, such as the water quality homogenization ability of the regulating tank, the aeration uniformity of the biochemical tank, and the sludge water separation effect of the sedimentation tank. Adjust the operating parameters (such as aeration rate and stirring intensity) based on the measured data. The safety acceptance should focus on checking the protective facilities, such as whether the equipment protective cover is installed in place, whether the emergency stop button is sensitive, whether the warning signs in dangerous areas are clear, and verifying the feasibility of the emergency plan (such as emergency drainage measures during power outages). After passing the debugging, it is necessary to organize and archive installation records, equipment parameters, and other materials to provide reference for later operation and maintenance.
