Water resource recovery includes but is not limited to rainwater, building wastewater, occasional discharge of swimming pool drainage, etc. A complete water resource recovery system can also be used for teaching purposes after completion. That is, on the basis of ensuring the normal operation of the water treatment equipment and facilities and the stable and up-to-standard effluent, the teaching effect is achieved through the measures of adding data display screen, process unit display board, process flow panoramic sand table, etc. The water system is equipped with intelligent operation and maintenance system to maximize the automation and intelligent level of the water treatment system, reduce operation and maintenance cost, and coordinate the water treatment station and artificial wetland with the surrounding campus environment through appropriate landscape design. As an important part of the water resource recovery system, a filtering mechanism is needed.

[0003] The filtering mechanism usually has multiple filtering devices to filter different sizes of impurities in the recovered wastewater. As the size of the impurities to be filtered decreases, the filter gap of the filter element inside the filtering device also decreases. Therefore, as the use time increases, the small aperture filter element inside the filtering device is easily clogged. The existing method is to clean the pollution by backwashing. However, since the filter gap of the filter element is fixed, when some impurities are clogged too deeply, the effect of backwashing is reduced, resulting in reduced cleaning effect and affecting the subsequent filtering efficiency.

[0055] In particular, during the forward filtration process, the backwash pump 24 and the second control valve 25 remain in a closed state, and the first control valve 22 needs to remain in an open state.

[0056] As a further illustration of the present embodiment, when backwashing is performed, the backwash pump 24 is started, and the second control valve 25 needs to be opened and the first control valve 22 needs to be closed at the same time.

[0057] In the present embodiment, please refer to Figure 5 , Figure 6 and Figure 7 , the outer diameter of the inner connecting pipe 17 is smaller than the inner diameter of the base 16, and the axis of the inner connecting pipe 17, the axis of the base 16, the axis of the filter housing 1 and the axis of the sleeve 2 are on the same vertical straight line; the bottom of each of the bases 16 is installed with a blowdown valve 20.

[0058] Specifically, when forward filtration is performed, the centrifugal pump 27 needs to be started, and the third control valve 26 is kept open, so that the sewage is injected into the filter housing 1 through the second outer pipe 19.

[0060] Please refer to Figure 14 The recycling system with the reclaimed water resource ecological recycling filtration equipment comprises basket gratings 101, one of which is connected with a water collecting pool 102, and the other is connected with an adjusting pool 103.
