Description

Technical Field

[0001] The present invention relates to the technical field of wastewater treatment, and in particular to a wastewater treatment device and a wastewater treatment method. Background Art

[0002] With the acceleration of industrialization and the continuous growth of population, water shortage and water pollution are becoming increasingly serious and have become urgent environmental challenges to be solved worldwide. As a key link in water resource recycling and environmental protection, the development and innovation of wastewater treatment technology is of great significance to the realization of sustainable water resource management.

[0003] Traditional wastewater treatment methods include physical treatment, chemical treatment, biological treatment and other processes. Physical treatment mainly removes suspended solids and larger particle impurities in wastewater by precipitation, filtration, centrifugation and other methods. In the process of wastewater treatment, the filtration process is mainly divided into primary filtration and fine filtration. The coarse filtration equipment is used to filter larger solid particles in the wastewater, while the fine filtration equipment is used to intercept solid particles, fibers and other impurities in the wastewater to prevent them from clogging or damaging the subsequent treatment equipment, and also help to improve the treatment effect. However, due to the small impurity particles filtered in the fine filtration process, the filter mesh diameter in the existing fine filtration equipment is small. After long-term use, it is very easy to be blocked by impurities in the wastewater, resulting in a significant decrease in filtration efficiency, which in turn affects the stable operation of the entire wastewater treatment system. In order to ensure the treatment effect, the filter needs to be cleaned or replaced frequently, which not only increases the maintenance cost and downtime of the equipment, reduces the efficiency of wastewater treatment, but also may cause secondary pollution during the cleaning process, further increasing the environmental burden.

[0016] S2. During filtration, the fine filter is driven by the driving roller and the driven roller to rotate continuously inside the filter bin. When rotating out, the wind wheel on the left first blows air to initially remove the sand and silt inside, and then the hammer at the lower end continuously knocks to further remove the sand and silt.

[0020] 2. When the driven rollers on both sides rotate, the small pulley 1 is driven to rotate through the large pulley 1 and the transmission belt 1, and then the wind wheel is driven to rotate inside the wind bin through the rotating shaft, so that the filtered residue is blown away and falls into the collection bin, and then falls into the internal storage of the collection pool through the collecting pipe. When the wind wheel on the left blows air to the left end of the fine filter, the mud and sand that are easy to fall out of the mesh of the fine filter can be initially blown out, so as to achieve preliminary removal of the mud and sand in the fine filter. When the wind wheel on the right rotates, the mud and sand that have been loosened but not fallen in the mesh of the fine filter after being knocked by the hammer can be removed, and the water stains remaining on the fine filter can be blown away, so as to improve the efficiency of repeated filtration.

[0021] 3. When the right driving roller rotates, the small pulley 3 is driven to rotate through the large pulley 2 and the transmission belt 3, and then the knocking rollers on both sides are rotated through the cooperation of the small pulley 2 and the transmission belt 2 on both sides, and then all the knocking hammers are driven to rotate, continuously knocking the lower end of the fine filter, so that the relatively firm sediment remaining on the fine filter is removed, thereby improving the effect of removing the residual sediment in the mesh of the fine filter.

[0022] 4. When the driving shaft drives the pinion to rotate, it synchronously drives the bevel gear 1 to rotate, and then drives the knocking shaft to rotate through the bevel gear 2, and then drives the knocking blade to rotate, continuously knocking the middle of the collection tube, so that the mud and sand inside the collection tube can easily fall into the disinfection pool, making it easy to collect and clean the mud and sand.

After being filtered through the fine filter 1011, it enters the interior of the disinfection tank 2, waiting for the addition of medicine for biochemical treatment. When the wastewater passes through the interior of the driving chamber 105, the water flow impacts the water wheel 106 to drive the water wheel 106 to rotate, and then drives the small gear 108 on the front side to rotate through the driving shaft 107.

When the driving shaft 107 drives the small gear 108 to rotate, it synchronously drives the bevel gear 1 1028 to rotate, and then drives the knocking shaft 1030 to rotate through the bevel gear 2 1029, and then drives the knocking blade 1031 to rotate, continuously knocking the middle part of the collection pipe 1020, so that the sand inside the collection pipe can easily fall into the disinfection pool 3, so that the sand that is easy to collect and clean can be collected. When the right driving roller 1010 rotates, the large pulley 2 1027 and the transmission belt 3 1026 It drives the small pulley three 1025 to rotate, and then through the cooperation of the small pulley two 1023 and the transmission belt two 1024 on both sides, the knocking rollers 1021 on both sides rotate, and then drive all the knocking hammers 1022 to rotate, and continuously knock on the lower end of the fine filter 1011, so that the relatively firm mud and sand remaining on the fine filter 1011 can be removed, thereby improving the effect of removing the residual mud and sand in the mesh of the fine filter 1011. When the wind wheel 1017 on the right side rotates, it can remove the mud and sand that have been loosened but not fallen in the mesh of the fine filter 1011 after being knocked by the knocking hammer 1022, and at the same time, it can blow away the residual water stains on the fine filter 1011, thereby improving the efficiency of repeated filtration.
