求翻译：实验流程图和装置图如图2-1和图2-2所示。整个装置主要由曝气槽和反应器两部分组成，所用材料为有机玻璃。废水由曝气槽经由进水泵打入反应器底部，自下而上流经反应器，经过三相分离器，将水与气、泥分离后，通过出水管再次循环至曝气槽。整个反应器的氧含量和温度由曝气槽的曝气装置和加热棒控制， DO控制在1.0mg/L以内，温度控制在20-30℃。是什么意思？

Flowchart and experimental device as shown in figures 2-1 and 2-2. Entire device is used primarily by aeration tank and reactor consists of two parts, materials used as plexiglass. Wastewater by aeration tank through the pump into the bottom of the reactor, flows through the reactor from the bottom up, after a three-phase separators, mud, water and gas separation, through the loop again to the aeration tank of outlet pipe. Oxygen content and temperature of the whole reactor by aeration device of aeration tank and heater control, DO controls within 1.0mg/L, temperature control 20-30 ℃.
