两极式微电解反应池1的主要参数：进水pH为3～6，HRT为4～6h，温度为常温。 The main parameters of the bipolar micro-electrolysis reaction pool 1: the pH of the influent water is 3-6, the HRT is 4-6 hours, and the temperature is normal temperature.
运行前，ABR反应器4与上流式好氧反应池5按负荷从低到高进行活性污泥培养与生物膜挂膜培养。ABR反应器4、上流式好氧反应池5、下流式膜过滤池7的主要参数：温度为15～30℃、HRT为6～8h、膜组件直径为10～20nm、膜操作压力为0.15～0.25MPa。 Before operation, the ABR reactor 4 and the upflow aerobic reaction tank 5 carry out activated sludge cultivation and biofilm-hanging cultivation according to the load from low to high. The main parameters of ABR reactor 4, upflow aerobic reaction tank 5, and downflow membrane filter tank 7: temperature is 15-30°C, HRT is 6-8h, membrane module diameter is 10-20nm, membrane operating pressure is 0.15- 0.25 MPa.
