How to cultivate activated sludge in combined sewage treatment equipment? Author: combined sewage treatment apparatus will be used in activated sludge treatment of sewage, sludge and microbial population is the general term of organic and inorganic materials to which they are attached, the activated sludge method using microorganism floc growing in suspension A type of aerobic treatment method for the treatment of organic sewage. The following editor will introduce how to cultivate the activated sludge of combined sewage treatment equipment. 1. Fill the aerobic pool with clean water (while introducing domestic sewage) to a certain water level, and pay attention to the water temperature. 2. Start the fan and blow the air according to the fan operating rules of the combined sewage treatment equipment. 3. Add filtered concentrated fecal water to the aerobic tank (when the fecal water is insufficient, it can be supplemented with the sludge in the septic tank and drainage ditch), so that the sludge concentration is not less than 1000mg/L, and the BOD reaches a certain value . 4. Activated sludge strains can be added when conditions permit to speed up the cultivation speed. 5. According to the activated sludge culture operation process, the reaction tank is aerated, stirred, settled, and drained. 6. Through microscopic inspection and determination of sedimentation ratio and sludge concentration, pay attention to observe the growth of activated sludge in the combined sewage treatment equipment. And pay attention to observe the online PH value, DO value changes, and adjust the process in time. 7. Determine the water quality of the initial water quality and the water quality of the supernatant in the drainage stage, and judge the activity of activated sludge and the situation of dominant bacteria according to the changes in the concentration of NH3-N, BOD, COD, NO3-, NO2-, etc. in the incoming and outgoing water. And thus adjust the water inflow, displacement, and fecal water. The above is how the editor cultivates the activated sludge of the combined sewage treatment equipment. The activated sludge in the equipment enables the sewage to be treated well and reduces the discharge of sewage.
