1. The water quality is black and smelly: the failure may be due to anaerobic reaction, which leads to poor sludge settleability and rising suspended solids. The solution is to strengthen aeration, promote sewage sedimentation, and at the same time reduce water inflow appropriately, improve the standard and make the system return to normal.
2. Ammonia nitrogen in effluent of biochemical pool exceeds the standard: the failure may be caused by too high ammonia nitrogen content in influent or too long sludge age, resulting in insufficient nitrifying bacteria. The solution is to reduce water inflow, improve compliance, increase reflux and promote nitrification.
3. Mud-water separation in sedimentation tank: The failure may be caused by high suspended matter content in sedimentation tank or failure of sludge discharge equipment. The solution is to strengthen the maintenance of sludge discharge equipment and increase the sludge discharge time of sedimentation tank.
4. Filter material blockage: The failure may be due to excessive backwashing strength of the filter, resulting in damage to the filter material. The solution is to check whether the backwashing intensity is set correctly, and adjust it in time if there is any problem.
5. Noise of the equipment: The failure may be caused by uneven installation of the equipment or damage to bearings, motors and other components. The solution is to check the installation of equipment to ensure smooth installation, and at the same time check whether the bearings, motors and other components are normal.
Generally speaking, the fault treatment of integrated sewage treatment equipment needs to take corresponding measures according to specific problems. During daily use, the equipment should be inspected and maintained regularly to ensure its normal operation.
