Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater treatment filter. Background Technology

[0002] In wastewater treatment, filtration is a crucial step. Typically, wastewater filtration uses filter media such as quartz sand. As wastewater flows through the filter media, solid impurities in the water are adsorbed, thus removing some of the solids. In current technology, the common filtration method involves wastewater being introduced from above and flowing naturally through the filter media under gravity. The filtered water then flows out from below to the next stage. However, this leaves a large amount of impurities remaining in the filter media, which usually needs to be removed and cleaned, making the process inconvenient. Utility Model Content

[0003] The purpose of this application is to provide a wastewater treatment filter to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this application provides the following technical solution: a wastewater treatment filter, comprising a housing 1, a first mesh plate 2 fixedly installed near the bottom of the inner cavity of the housing 1, a second mesh plate 3 installed near the top of the inner cavity of the housing 1, filter media 4 filled between the first mesh plate 2 and the second mesh plate 3, an end cap 5 sealing the top of the housing 1, an inlet 6 communicating with the inner cavity of the housing fixedly installed on the end cap 5, and a drain outlet communicating with the interior of the housing fixedly installed on one side of the housing 1. 8. A valve is fixedly installed on the drain outlet 8, which is located above the second mesh plate 3. A water inlet 7 communicating with the interior is fixedly installed on one side of the outer shell 1.

[0010] In summary, the technical effects and advantages of this utility model are as follows:

[0011] In this invention, wastewater enters through the inlet, is filtered by the filter media, and then discharged through the outlet. During maintenance, the inlet and outlet are closed, while the drain outlet and inlet are opened. Water from the inlet enters the housing and washes the filter media from bottom to top. Simultaneously, the ultrasonic generator and ultrasonic transducer are activated, allowing the filter media to be reliably cleaned under ultrasonic action. The wastewater from the cleaning process is discharged through the drain outlet, thus achieving efficient and convenient maintenance. Attached Figure Description
