废水处理设备是用于处理废水的各种设施和设备的总称。根据不同的处理方法和流程，常用的废水处理设备可以分为以下几类：

Wastewater treatment equipment is a general term for various facilities and equipment used to treat wastewater. According to different treatment methods and processes, commonly used wastewater treatment equipment can be divided into the following categories:

　　预处理设备：预处理设备的作用是对废水进行初步的处理，如去除大颗粒杂质、悬浮物、油脂等。常用的预处理设备包括格栅、筛网、沉砂池、除油器等。

Pretreatment equipment: The function of pretreatment equipment is to perform preliminary treatment on wastewater, such as removing large particle impurities, suspended solids, oils, etc. The commonly used pre-treatment equipment includes grilles, screens, sedimentation tanks, oil removers, etc.

　　生物处理设备：生物处理设备是利用微生物降解有机污染物的设备，如活性污泥法中的曝气池、生物滤池、生物转盘等。这些设备可以有效地去除废水中的有机物、氮、磷等污染物。

Biological treatment equipment: Biological treatment equipment is a device that utilizes microorganisms to degrade organic pollutants, such as aeration tanks, biofilters, and biological turntables in activated sludge processes. These devices can effectively remove pollutants such as organic matter, nitrogen, and phosphorus from wastewater.

　　化学处理设备：化学处理设备是利用化学反应来处理废水中的污染物的设备，如中和池、氧化池、电解池等。这些设备可以去除废水中的重金属离子、有害化学物质等。

Chemical treatment equipment: Chemical treatment equipment is a device that uses chemical reactions to treat pollutants in wastewater, such as neutralization tanks, oxidation tanks, electrolysis tanks, etc. These devices can remove heavy metal ions, harmful chemicals, etc. from wastewater.

　　物理处理设备：物理处理设备是利用物理方法来处理废水中的污染物的设备，如过滤器、吸附塔、离心机等。这些设备可以去除废水中的悬浮物、杂质、油污等。

Physical treatment equipment: Physical treatment equipment is a device that uses physical methods to treat pollutants in wastewater, such as filters, adsorption towers, centrifuges, etc. These devices can remove suspended solids, impurities, oil stains, etc. from wastewater.

　　膜处理设备：膜处理设备是利用膜分离技术来处理废水的设备，如超滤膜、反渗透膜等。这些设备可以去除废水中的微小颗粒、有机物、无机物等。

Membrane treatment equipment: Membrane treatment equipment is a device that uses membrane separation technology to treat wastewater, such as ultrafiltration membranes, reverse osmosis membranes, etc. These devices can remove small particles, organic matter, inorganic matter, etc. from wastewater.

　　以上是常用的废水处理设备的分类和介绍，不同的设备和工艺适用于不同的废水处理场景和需求。在实际应用中，需要根据具体情况选择合适的设备和工艺，以达到的处理效果。

The above is the classification and introduction of commonly used wastewater treatment equipment. Different equipment and processes are suitable for different wastewater treatment scenarios and needs. In practical applications, it is necessary to choose appropriate equipment and processes based on specific circumstances to achieve the best processing effect.
