Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture wastewater, in particular to a decentralized integrated aquaculture wastewater treatment device. Background Art

[0002] A large amount of wastewater is generated during the aquaculture process. The wastewater mainly comes from feed residues, aquaculture biological metabolites and cleaning water of aquaculture equipment. These wastewaters contain high concentrations of organic matter, nitrogen, phosphorus and other nutrients. Direct discharge will cause serious pollution to the water environment. Therefore, aquaculture wastewater needs to be treated.

[0003] The prior art provides an integrated aquaculture wastewater treatment device (Announcement No. CN221166037U), which includes a wastewater treatment pipe; a filter screen is installed at the water inlet of the wastewater treatment pipe, a medicine box is installed on the wastewater treatment pipe, a scraper that passes through the filter screen is installed in the wastewater treatment pipe, a rotating part that extends into the wastewater treatment pipe is installed in the medicine box, and a driving part for driving the scraper and the rotating part to rotate simultaneously is installed on the wastewater treatment pipe, and the scraper is used to scrape the surface of the filter screen when rotating. The utility model proposes an integrated aquaculture wastewater treatment device, which solves the problem of large pieces of sludge clogging the filter screen during the wastewater treatment process, which may affect the effect of wastewater treatment. At the same time, after the wastewater is filtered, it is inconvenient to merge the filtered wastewater with the medicine in time, making it difficult to effectively remove harmful substances in the wastewater.

[0004] The above-mentioned integrated aquaculture wastewater treatment device only provides filter cleaning function and wastewater and reagent mixing function during actual use. However, the sludge filtered out by the filter will still accumulate in the wastewater treatment pipe. When too much sludge accumulates in the wastewater treatment pipe, it is easy to cause the wastewater treatment pipe to be blocked, thereby affecting the wastewater treatment efficiency. Therefore, we need to propose a decentralized integrated aquaculture wastewater treatment device. Utility Model Content
