Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a wastewater treatment and purification device for environmental engineering. Background Technology

[0002] Wastewater treatment in environmental engineering is the process of purifying wastewater to meet the water quality requirements for discharge or reuse. This process is widely used in many fields, including construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering, and is gradually becoming more common in daily life. Wastewater treatment projects separate or convert pollutants contained in wastewater into harmless substances through various methods, thereby purifying the wastewater. The existing publication number CN217921715U discloses a wastewater treatment purification device for environmental engineering. It stores a certain amount of chemical reagents in a storage tank, and then uses an intermittent feeding component to allow the chemical reagents in the storage tank to flow intermittently into the purification tank. This solves the problem of insufficient mixing and reaction between the reagents and wastewater due to a large amount of chemical reagents added at once, resulting in poor purification effects. However, the filter screen in this purification device is not easy to remove, making it difficult for workers to clean the filter screen, which in turn affects the filtration and adsorption effect of impurities and harmful substances in the wastewater, bringing certain adverse effects to practical use. Therefore, improvements are needed. Utility Model Content

[0003] The purpose of this utility model is to provide a wastewater treatment and purification equipment for environmental protection engineering. The lifting device enables the removal of the filter screen and activated carbon particles, which facilitates the cleaning of the filter screen and the replacement of the activated carbon particles by the staff. This ensures the filtration and adsorption effect of the purification equipment on impurities and harmful substances in the wastewater, bringing certain benefits to practical use and solving the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a wastewater treatment and purification device for environmental engineering, comprising a filter box, with drain pipes connected through both sides of the filter box near its bottom, support legs fixedly installed at the four corners of the bottom of the filter box, a purification cylinder fixedly installed in the middle of the top of the filter box, through grooves opened on the top of the filter box and on both sides of the purification cylinder, water inlet pipes connected through both sides of the top of the purification cylinder, a water outlet pipe connected through the middle of the bottom of the purification cylinder and equipped with a solenoid valve, partitions fixedly installed inside the filter box and on both sides of the through grooves, a push plate provided between the partitions and near its bottom, a filter screen fixedly installed on the top of the push plate and near its inner side, activated carbon particles provided on the outer side of the filter screen and on the top of the push plate, a first motor fixedly installed in the middle of the bottom of the filter box, a threaded rod fixedly installed at the output end of the first motor, a threaded sleeve connected to the external thread of the threaded rod, L-shaped rods fixedly installed on both sides of the threaded sleeve, and the other end of the L-shaped rods passing through the interior of the filter box and fixedly connected to the push plate.
