[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Chemical agents are added to the reaction pool for chemical reaction. At the same time, through the mechanism of electrical neutralization adsorption and sediment capture, the colloidal particles and tiny suspended solids in the wastewater are aggregated to form larger flocculants, and then flow into the primary sedimentation tank through the pipeline, and settle to the bottom of the tank under the action of gravity to form physical and chemical sludge, and then discharged to the regulating tank, and the mixer in the regulating tank is used to homogenize and equalize the wastewater to form relatively stable wastewater. The wastewater is then The pipeline flows into the anaerobic tank, and under anaerobic conditions, the organic matter in the wastewater is decomposed into methane, carbon dioxide and other easily biodegradable organic matter through the action of anaerobic microorganisms, and then the wastewater is discharged into the MBR biochemical tank. The organic pollutants in the sewage are removed by the MBR biochemical system and then transported to the intermediate water tank. The wastewater is reverse osmotic through the security filter in the intermediate water tank. Driven by pressure, the wastewater finally reaches the reuse water standard and is discharged into the clear water tank for standby use. The concentrated water produced by reverse osmosis is transported to the MVR evaporator, and the concentrated water is produced into mixed salt crystals by the MVR evaporator. After passing through the centrifuge, the mixed salt solid is obtained, and then it is bagged for sale. The wastewater is filtered in the grid pool 1. When there are debris in the water, larger suspended matter in the wastewater may block the filter plate 101 in the grille pool 1. In order to prevent such incidents from happening, first, the wastewater is introduced into the grille pool 1, and then the anti-blocking shaft 44 is started to rotate. During the rotation, the anti-blocking shaft 44 will drive the multiple groups of striking columns 441 fixed on the shaft to rotate.
