Sponge community LID facility and method for treating initial rainwater
The invention provides a sponge community LID facility for treating initial rainwater, and belongs to the field of sewage treatment. Comprising a conventional treatment unit, a detection probe, a PLC (Programmable Logic Controller), a sulfur powder adding device, an advanced treatment unit and an alkali liquor barrel, wherein fungus bags are uniformly arranged in the advanced treatment unit; a first water outlet pipe of a first water outlet area above the conventional treatment unit is communicated with a second water inlet pipe of a second water inlet area below the advanced treatment unit, a powdered sulfur liquid bucket is communicated with the first water outlet pipe through a powdered sulfur liquid pump, and an alkali liquor bucket is communicated with the second water inlet pipe through an alkali liquor pump; the NO3 <-> detection probe and the pH probe are electrically connected with the PLC respectively. The sewage treatment method comprises the following steps: reducing NO3 <-> into NO2 <-> by controlling sulfur autotrophic denitrification, and oxidizing NH4 < + > into N2 by taking NO2 <-> as an electron acceptor under the action of anaerobic ammonium oxidation bacteria. The method has the beneficial effect that the total nitrogen in the effluent finally reaches the IV-class standard of surface water.
本发明提供了一种处理初期雨水的海绵小区LID设施，属于污水处理领域。包括常规处理单元、检测探头、PLC控制器、硫粉投加装置、深度处理单元、碱液桶，深度处理单元内均匀设有菌包；常规处理单元上方第一出水区的第一出水管与深度处理单元下方第二进水区的第二进水管相连通，硫粉药液桶经硫粉药液泵连通第一出水管，碱液桶经碱液泵连通第二进水管；NO3‑检测探头、pH探头分别与PLC控制器电连接。污水处理方法是通过控制硫自养反硝化将NO3‑还原至NO2‑阶段，在厌氧氨氧化菌的作用下，以NO2‑为电子受体，将NH4+氧化成N2。本发明的有益效果：最终使得出水总氮达到地表水Ⅳ类标准。
