Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage sedimentation and purification device for environmental protection engineering. Background Art

[0002] Environmental engineering sewage treatment refers to the process of purifying and treating sewage by various methods such as physical, chemical and biological methods, aiming to reduce or eliminate the negative impact of sewage on the environment. This treatment usually includes pretreatment, main treatment and deep treatment to ensure that sewage meets specific water quality standards before discharge or reuse. The goal of sewage treatment is to protect the sustainable use of water resources, safeguard human health, promote economic development, and reduce damage to the natural environment.

[0003] The announcement number CN221275549U discloses a sewage sedimentation and purification device for environmental protection engineering. By driving a water pump to work, the initially filtered sewage can be conveniently introduced into the sedimentation tank through a water guide pipe. By adding flocculants to the flocculant addition port, the sewage can be conveniently mixed with the flocculants to precipitate. By driving the motor device to work, the rotating rod can be rotated to drive the stirring rod to rotate, so that the sewage and the flocculants are more quickly and evenly mixed, which is convenient for improving the sedimentation speed of the mixing reaction. By arranging an ultraviolet sterilization lamp on the inner wall of the sedimentation tank for use, it is convenient to sterilize and disinfect the internal sewage. By arranging a filter baffle inside the sedimentation tank, it is convenient to isolate the precipitated debris from the sewage. The precipitated impurities can be discharged through the sewage outlet. By using a cleaning scraper for use, it is convenient to effectively clean the filter baffle to prevent impurities from easily clogging it and affecting the use effect. By arranging a connecting pipe and a filter purification box on one side of the sedimentation tank for use, it is convenient to further filter and purify the filtered and precipitated sewage, improve its filtering and purification effect, facilitate better recycling, and facilitate further improving the practicality and functionality of the overall device structure.

[0004] The sewage sedimentation and purification device of this environmental protection project can conveniently isolate the precipitated debris from the sewage by arranging a filter baffle inside the sedimentation tank, and the precipitated impurities can be discharged through the sewage outlet. The cleaning scraper is used in conjunction with it to facilitate the effective cleaning of the filter baffle to prevent impurities from easily clogging it and affecting the use effect. However, after the sewage has gone through the sedimentation process, the solid particles and organic matter in the sewage will form sediment at the bottom of the sedimentation tank. The impurities are easy to adhere to the inner wall of the sewage outlet when discharged. Long-term accumulation is easy to cause the sewage outlet to be blocked, affecting the efficiency of sewage discharge, and then affecting the efficiency of sewage treatment. Utility Model Content
