[0002] A wastewater treatment machine is a machine used to treat wastewater. It is widely used in enterprises or factories. It helps to purify water sources and protect the ecological environment. The wastewater treatment process involves multiple treatment steps, including removing suspended matter, treating organic matter, removing hardness and heavy metals, etc. Common treatment technologies include filtration treatment, sedimentation treatment, biological treatment, chemical treatment, activated carbon adsorption, hydrolysis technology and ion exchange technology, etc. There are many types of wastewater treatment machines, and most types of wastewater treatment machines are equipped with filters for preliminary filtering of impurities.

[0003] Since the volume of the wastewater treatment machine is relatively large, in order to ensure that the water flows more smoothly, the space of the water flow channel inside is also large. At this time, the size of the corresponding filter will also be relatively large. In addition, when the conventional wastewater treatment machine is in use, the filter on it is fixed inside the machine body with multiple fastening bolts. The filter is large in size and difficult to lift by manpower. It is fixed by bolts and requires manual entry into the machine body for loading and unloading after bolting, which will bring inconvenience to the subsequent replacement of the filter. In view of this, we proposed a wastewater treatment machine that is easy to replace the filter. Utility Model Content
