Abstract
Description
Technical Field
[0001] This utility model relates to the field of rural domestic sewage technology, specifically to a sampling device for rural domestic sewage. Background Technology
[0002] Rural domestic sewage refers to a type of water body generated during residents' production activities, including water discharged from toilets, bathrooms, kitchens, laundry rooms, etc. The main components of domestic sewage include water, organic matter, inorganic salts, microorganisms, etc. The structure of sewage sampling wells is relatively simple, mostly consisting of a trough made of concrete blocks. Usually, the sampling structure needs to be placed inside the sampling well.
[0003] The structure and quantity of various impurities in rural domestic sewage vary at different times. Therefore, in order to improve the accuracy of the sampling data, multiple samplings are required. This necessitates the preparation of multiple sampling tubes and the sampling of samples at different time periods, which requires dedicated personnel to handle the sampling at regular intervals, making the sampling process quite cumbersome.
[0004] According to Chinese Patent Publication No. CN221217278U, "A Sampling Device for Rural Domestic Sewage Treatment," the main method involves placing a sampling box inside a sampling well, with the inlet connected to the outlet of the sewage treatment system. The sewage is pretreated using volcanic rock and zeolite fillers in the pretreatment zone. The sewage then passes through an opening one into a deep treatment zone, where activated carbon fillers provide further treatment. The treated sewage then passes through an opening two into the sampling zone and flows out through an anti-backflow component at the outlet. This invention improves the effluent quality of rural domestic sewage treatment facilities, reduces pollutant emissions, and prevents backflow of river water and other water sources into the sewage treatment system through the outlet. However, the sampling data requires regular processing by designated personnel, leading to reduced sampling efficiency.
[0005] Therefore, a sampling device for rural domestic sewage is proposed to solve the problem that the sampling data needs to be processed by a dedicated person at regular intervals, which leads to a decrease in sampling efficiency. Utility Model Content
[0006] The technical problem this invention aims to solve is that the sampling data needs to be processed by a designated person at regular intervals during the sampling process, which leads to a decrease in sampling efficiency. Therefore, this invention proposes a sampling device for rural domestic sewage.
