Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, and particularly relates to a stirrer structure for preventing the leakage of walnut shell filter media. Background Art

[0002] The walnut shell filter uses walnut shells as filter media. The specially treated walnut shells have a large surface area and strong adsorption capacity, so the removal rate is high. Due to the property of being hydrophilic but not lipophilic, stirring is used during backwashing to make the walnut shells rub against each other during movement, so the desorption ability is strong, the regeneration ability is strong, the chemical stability is good, which is conducive to the long-term stable performance of the filter. In order to prevent the leakage of walnut shell filter media, a filter plate is generally provided in the walnut shell filter. After the filter plate is used for a period of time, a large amount of impurities will adhere to the filter plate, affecting the filtering effect. Relying solely on backwashing to clean the filter plate has a poor effect. Summary of the Utility Model
