Description

Technical Field

[0001] The utility model relates to the technical field of filtration for sewage treatment, and more specifically, to a filtration device for sewage treatment. Background Art

[0002] In the existing technology, the filtration device for sewage treatment often lacks an effective sampling mechanism during the filtration process, which directly affects the detection and analysis of the sewage treatment effect. Specifically, this deficiency is manifested in the following two aspects:

[0003] First, the existing filtration devices for sewage treatment have not fully considered the convenience of sampling operations in their design. In the sewage treatment process, sampling and testing the water quality before and after filtration is an important step in evaluating the filtration effect and adjusting the treatment process. However, existing filtration devices often do not have a dedicated sampling interface or the sampling design is not user-friendly, which requires operators to spend a lot of time and energy when sampling. This not only reduces work efficiency, but may also affect the accuracy of the sampling results due to the complexity of the sampling operation.

[0004] Secondly, existing filtration devices for sewage treatment lack flexibility in operation. Due to the particularity of the sewage treatment environment, such as sewage, sludge, etc., operators need to face harsh working conditions when taking samples. This not only increases the difficulty of work, but may also pose a threat to the health of operators. In addition, due to the limitations of the equipment structure, operators may need special tools or skills when taking samples, which further reduces the convenience of operation.
