Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a small-scale decentralized sewage treatment device. Background Art

[0002] Centralized sewage treatment relies heavily on sewage collection pipe networks, with large investments and high operating costs, making it unsuitable for most towns and rural areas. Considering the various shortcomings of centralized sewage treatment as a terminal treatment in terms of effectiveness and applicability in recycled sewage, the application direction of existing sewage treatment equipment should be shifted to on-site treatment and source control of wastewater, so as to realize the mass production of various decentralized treatment technologies and small-scale equipment.

[0003] Existing decentralized sewage treatment equipment often uses "a small decentralized high-efficiency sewage treatment equipment" disclosed in the announcement number "CN215855654U". The decentralized sewage treatment equipment uses multiple biochemical reaction cylinders and multiple sedimentation cylinders to treat sewage through the connection between pipes. However, multiple biochemical reaction cylinders and multiple sedimentation cylinders will cause the sewage treatment process to be too complicated, difficult to operate, and too costly, which does not meet the current market demand for decentralized sewage treatment equipment. In addition, the single connection between the pipes causes the sewage treatment to be a one-time treatment, and the sewage cannot obtain a better treatment effect in the equipment.

[0004] To this end, we designed a small decentralized sewage treatment equipment. Utility Model Content
