Domestic wastewater treatment device for environmental protection engineering

Abstract

The invention discloses a domestic wastewater treatment device for environmental protection engineering, and particularly relates to the technical field of wastewater treatment. The domestic wastewater treatment device comprises a machine body, a wastewater cavity is formed in the machine body, a top cover is fixedly installed at the top of the machine body through screws, a limiting assembly is arranged at the bottom of the top cover, and a driving assembly is arranged at the bottom of the machine body; a filter barrel assembly is arranged in the wastewater cavity; the limiting assembly comprises an extension ring, and the extension ring is welded to the bottom of the top cover. By arranging the limiting assembly, the driving assembly and the filter barrel assembly, solid impurities such as fruit peels and vegetable leaves in water can be effectively prevented from blocking filter holes when filtered, the filter efficiency is guaranteed, meanwhile, the filter barrel assembly can be directly detached to be cleaned, the interior is convenient to clean, and disassembly and assembly are relatively simple and time-saving, and thus the actual use effect of the device is relatively good.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, and more specifically, the invention relates to a domestic wastewater treatment device for environmental protection engineering. Background technique [0002] Domestic wastewater refers to the wastewater discharged by residents in their daily life. Its main source is residential buildings and public buildings. Domestic sewage cannot be discharged directly because the organic matter contained in it is extremely unstable and easy to rot, causing stench and polluting the environment. Before the domestic wastewater is discharged, it needs to be treated with a domestic wastewater treatment device. [0003] Although the domestic wastewater treatment device in the prior art can be used normally, there are still many shortcomings in actual use. For example, when the domestic wastewater treatment device in the prior art filters solid impurities such as fruit peels and vegetable leaves in the ...

Problems solved by technology

[0003] Although the domestic wastewater treatment device in the prior art can be used normally, there are still many shortcomings in actual use. For example, when the domestic wastewater treatment device in the prior art filters solid impurities such as fruit peels and vegetable leaves in the water, these Solid impurities can easily block the mesh of the filter, which affects the filtration efficiency. At the same time, under the continuous impact of the water flow, these solid impurities will be stuffed into the mesh, making it difficult to clean the filter later, which makes life in the prior art The actual use effect of the wastewater treatment device is poor
