[0035] One side of the filter jar 2 is connected with a ball valve B3, which is used to control the on-off of water flow and is convenient for maintenance and repair of the equipment.

[0036] One side of the water tank 18 is connected with a drain pipe 19.

[0037] The top of the filter jar 2 is connected with a support 11, and the support 11 and the filter jar 2 are fixedly arranged. The top of the support 11 is connected with a distribution water tank 10, which is connected to the top of the support 11 through bolts.

[0040] Specifically, in use, the sewage first flows into the distribution water tank 10, and the distribution water tank 10 can make the sewage enter the filter tank 2 more evenly, and after entering the filter tank 2, the sewage passes through the filter mechanism composed of the anthracite 15, the quartz sand 16 and the gravel 17 in turn from top to bottom, the gravel 17 is located at the bottom of the filter tank 2, and has larger particles, mainly plays a role of supporting the upper layer of filter material and preliminarily filtering large-particle impurities, the quartz sand 16 is above the gravel 17, and can further filter smaller-particle impurities, and the anthracite 15 is in the uppermost layer, and has rich pore structure, has good adsorption and filtering capacity for impurities such as organic matter and colloid in the sewage, and through the synergistic effect of the three layers of filter materials, various impurities in the sewage are effectively intercepted, and the filtered clean water flows out through the outlet 14 on the surface of the filter tank 2, so that the sewage is preliminarily purified;

[0041] With the continuous filtering process, the impurities intercepted on the filter materials gradually increase, resulting in the increase of the filtering resistance, and the water level in the filter tank 2 gradually rises, when the water level rises to the inlet of the siphon auxiliary pipe 8, the water begins to flow into the siphon auxiliary pipe 8, and flows to the siphon destruction bucket 13 along the siphon auxiliary pipe 8, with the continuous rise of the water level in the siphon destruction bucket 13, when reaching a certain height, the water in the siphon destruction bucket 13 will overflow, so that the air in the siphon A1 is gradually discharged, forming a siphon phenomenon, and the siphon A1 and the siphon B7 begin to work, and the water in the water tank 18 flows into the filter tank 2 quickly under the siphon effect through the siphon B7;

[0042] After the water in the water tank 18 flows into the filter tank 2 through the siphon B7, the filter materials are reversely washed, at this time, the water flow direction is opposite to that in the filtering process, and the strong water flow impact force will wash off the impurities adsorbed on the anthracite 15, the quartz sand 16 and the gravel 17, the reverse washing strength can be adjusted through the reverse washing strength adjuster 4 at the bottom of the siphon B7 in the water tank 18, so as to ensure that the impurities can be effectively washed off, and the filter materials will not be excessively damaged, and the washed impurities flow out through the siphon A1 along with the water flow to the water tank 18, and then are discharged through the drain pipe 19 on one side of the water tank 18;

[0043] When the backwashing is completed, the water level in the filter tank 2 is lowered, and as the water level is lowered, the water level in the siphon breaking tank 13 is also lowered, when the water level in the siphon breaking tank 13 is lowered to a certain extent, air will enter the siphon pipe A1 through the siphon auxiliary pipe 8 to break the siphon phenomenon, the siphon pipe A1 and the siphon pipe B7 stop working, the backwashing process is completed, and the filter returns to the normal filtering state, and in the whole process, the supporting rods 9 at the bottom of the siphon pipe A1 and the siphon pipe B7 play a supporting role to ensure the stability of the siphon pipe; the ball valve A5 and the ball valve B3 can respectively control the on-off of the water flow on one side of the siphon pipe A1 and the filter tank 2, which is convenient for the maintenance and overhaul of the equipment.
