Description

Technical Field

[0001] The utility model relates to the technical field of water treatment devices, in particular to a water treatment device with biological filter material. Background Art

[0002] The water treatment device with biological filter material is to effectively improve water quality and reduce the discharge of pollutants by microorganisms on the biological filter material to attach and metabolize organic matter and ammonia nitrogen in the water. The microbial community in the biological filter is relatively stable and sensitive to fluctuations in water quality. However, when the water quality changes drastically, such as a sudden increase in organic load or a large temperature fluctuation, the microorganisms may not be able to adapt quickly, resulting in a decrease in the treatment effect. Therefore, those skilled in the art provide a water treatment device with biological filter material to solve the problems raised in the above background technology. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The utility model can be used to pre-treat raw water through a sedimentation tank, so as to cause solid suspended matter to settle down and reduce the impact on subsequent treatment units. Through the use of a sedimentation tank, suspended matter, silt and some organic matter can be effectively removed, thereby reducing the sensitivity of the microbial community in the biological filter to water quality fluctuations, thereby solving the problem that when the water quality changes drastically, the microorganisms may not be able to adapt quickly, resulting in a decrease in the treatment effect. The output end of the sedimentation tank water inlet pipe is fixedly connected with a nozzle, which helps to reduce eddy currents and violent agitation in the water body, reduce the possibility of re-suspension of suspended matter, and promote the sedimentation of suspended matter.

[0016] 2. As time goes by, the biofilm in the biofilter will gradually accumulate pollutants, resulting in a decrease in filter efficiency. Therefore, the biofilter and the filter layer need to be replaced or cleaned. The utility model can lift the biomaterial frame through a hydraulic cylinder to facilitate the replacement or cleaning of the biofilter and the filter layer. BRIEF DESCRIPTION OF THE DRAWINGS
