TECHNICAL FIELD

[0001] The utility model relates to the technical field of ocean sewage treatment, especially to the ocean fishery wharf sewage treatment device. BACKGROUND

[0002] With the continuous development of ocean fishery, the problem of sewage treatment in fishery wharf is increasingly prominent. In the ocean fishery activities, a large amount of sewage containing solid waste will be produced in the wharf area. If these sewage is directly discharged without effective treatment, it will cause serious damage to the marine ecosystem, such as leading to marine eutrophication and decline of biodiversity.

[0003] The existing fishery wharf sewage treatment equipment and method have many shortcomings. On the one hand, most of the equipment lack convenient displacement function and cannot be flexibly adjusted according to the berthing position of fishery vessels, increasing the labor intensity and processing difficulty. On the other hand, many equipment are not equipped with effective solid waste sedimentation collection structure, which cannot completely collect and treat the solid waste in sewage, so that part of the solid pollutants are discharged into the ocean with sewage, causing long-term pollution to the marine environment.

[0004] In addition, most of the existing fishery wharf sewage treatment equipment do not have the function of consuming nutrients in water (such as algal stems). This not only makes it difficult to effectively remove biological impurities in the sewage treatment process, increasing the complexity and cost of subsequent treatment, but also leads to the fact that the discharged sewage still contains a high concentration of nutrients, further aggravating the problem of marine eutrophication and threatening the balance of marine ecology.

[0005] In order to overcome the above-mentioned shortcomings, the inventor has invented the ocean fishery wharf sewage treatment device. CONTENT OF THE UTILITY MODEL
