Description

Technical Field

[0001] The utility model relates to the technical field of aerated biological purification pools for domestic sewage, in particular to an aerated biological purification pool for treating rural domestic sewage. Background Art

[0002] As we all know, aeration refers to the process of forcing oxygen in the air to transfer into the liquid in order to obtain sufficient dissolved oxygen. In addition, aeration also prevents the suspended matter in the pool from sinking and strengthens the contact between organic matter, microorganisms and dissolved oxygen in the aerated biological purification pool for rural domestic sewage, thereby ensuring that the microorganisms in the pool can oxidize and decompose organic matter in the sewage under the condition of sufficient dissolved oxygen.

[0003] In real life, there are often some toilet paper, small stones and other debris mixed in the water in domestic sewage, which are then transported to the aerated biological purification pool for treating rural domestic sewage. With the action of gravity, they gather at the bottom of the pool, and the staff needs to clean the bottom of the pool regularly to prevent excessive accumulation of debris from affecting the efficiency of the device. However, each cleaning requires the sewage in the pool to be discharged to the lower part of the filter plate before cleaning can be carried out. Most of the filter plates are generally fixed in the middle and lower part of the pool, and the filter plate cannot be moved above the liquid surface for cleaning. Therefore, the practicality is not very good. Secondly, when the filter plate is blocked and needs to be cleaned, the staff needs to jump into the pool to disassemble the filter plate, but cannot stand outside to disassemble the filter plate. The disassembly is not very convenient, so the practicality is not very good, and there is room for improvement. Utility Model Content
