There may be many reasons why the effluent quality of the sedimentation tank of integrated sewage treatment equipment does not meet the standard. The following are some common reasons:

       1Insufficient sludge concentration: The sedimentation tank is a key unit for removing suspended solids and some organic matter through sedimentation. If the sludge concentration is insufficient, the sludge cannot effectively capture and settle suspended solids during the sedimentation process, resulting in a higher concentration of suspended solids in the effluent.

       2Insufficient settling time: Suspended solids in the settling tank need enough time to settle and separate. If the sedimentation time is insufficient, the sedimentation tank cannot fully complete the sedimentation of suspended solids, causing part of the suspended solids to be brought to the effluent, resulting in substandard water quality.

       3Insufficient stirring in the sedimentation tank: The operating status of the mixing system in the sedimentation tank will affect the sedimentation effect. Insufficient stirring will cause the suspended solids to be unable to fully combine with the sludge, affecting the sedimentation effect and thus affecting the effluent quality.

       4, Sedimentation tank leakage: Sedimentation tank leakage will cause mixing between incoming water and effluent water, thereby reducing the sedimentation effect and affecting the effluent water quality.

       5, Sedimentation tank overload: The design capacity and processing capacity of the sedimentation tank need to match the incoming water volume. If the incoming water volume is greater than the processing capacity of the sedimentation tank, the sedimentation tank will not be able to fully complete the sedimentation process, resulting in substandard effluent water quality.

       6Unreasonable operating parameters of the sedimentation tank: The operating parameters of the sedimentation tank, such as stirring speed, sludge concentration, inlet water flow, etc., need to be adjusted and controlled according to the actual situation. If the parameter settings are unreasonable, it will affect the sedimentation effect and thus affect the effluent quality.

       7Equipment failure or damage:Integrated sewage treatment equipmentFailure or damage may cause the sedimentation tank to not operate normally, affecting the sedimentation effect and effluent water quality.

       To solve the problem of substandard water quality in the sedimentation tank, the following measures can be taken:

       1Check and repair the leakage problem in the sedimentation tank to ensure the separation between the inlet and outlet water.

       2, adjust the stirring speed and time of the sedimentation tank according to the actual situation to ensure that the suspended matter is fully settled.

       3, check and repair equipment failure or damage to ensure normal operation of the sedimentation tank.

       4, adjust the processing capacity of the sedimentation tank according to the incoming water quality and flow rate to avoid overload.

       5, regularly monitor the effluent quality of the sedimentation tank, and make corresponding adjustments and improvements based on the monitoring results.
