When the wastewater filtering tower 7 is used for filtering, the sewage draining outlet 74 is in a closed state, the water level entering the wastewater filtering tower 7 gradually rises to reach the second filtering layer 73 for filtering, and the water level continues to rise to reach the first filtering layer 72 along with the increase of water for filtering again.

With reference to fig. 5 and 6, the upper surface of the wastewater filtering tower 7 is communicated with the recycling pipe 8, the bottom end of the recycling pipe 8 in the wastewater filtering tower 7 is higher than the first filter layer 72, the bottom end of the recycling pipe 8 is sleeved with the filter screen 81, and the filter screen 81 is arranged on the recycling pipe 8, so that the purpose of filtering again before water recycling is achieved, and the cleanness of the reused water is ensured. The other end of the recycling pipe 8 can be connected with a water inlet pipe 11, the middle of the recycling pipe 8 is connected with a water pump 9, and water filtered in the waste water filtering tower 7 can be pumped into the water inlet pipe 11, so that the waste water is recycled. The bottom of the wastewater filtering tower 7 is in a necking shape and is provided with a drain outlet 74, and the drain outlet 74 is provided with a valve. After the liquid level surpassed first filter layer 72, increase along with the continuation of water, when the liquid level rose gradually and arrived the mouth of pipe height of recycling pipe 8, the water pump 9 of recycling pipe 8 connection was opened, with water suction inlet tube 11, thereby flow into and wash case 1, reach the purpose with waste water cyclic utilization, in addition, when water filters through second filter layer 73, the debris of aquatic are filtered second filter layer 73 surface, when debris accumulation was more, self weight made debris fall, then the tower wall of following the waste water filter tower 7 of slope glides to drain 74.

As shown in fig. 5, the upper surface of the wastewater filtering tower 7 is fixedly communicated with a back flushing pipe 71, one end of the back flushing pipe 71, which is positioned outside the wastewater filtering tower 7 and is close to the outside of the wastewater filtering tower 7, is provided with a controllable valve, one end of the back flushing pipe 71, which is far away from the wastewater filtering tower 7, can be connected with an external water source, one end of the back flushing pipe 71, which is positioned inside the wastewater filtering tower 7, is fixedly connected with a water spray head 711, which enlarges the water spray area, and can easily flush impurities on the lower surfaces of the first filtering layer 72 and the second filtering layer 73, and the back flushing pipe 71 inside the wastewater filtering tower 7 is communicated with. And finally, during sewage discharge, opening a valve at the sewage discharge port 74, discharging the impurities downwards to the sewage discharge port 74 for one time, opening a valve of the backflushing pipe 71, allowing clean water to flow through the backflushing pipe 71 to reach the first filtering layer 72 and the second filtering layer 73, flushing down the impurities attached to the lower surface of the backflushing pipe, allowing the water in the backflushing pipe 71 to flow downwards through the recycling pipe 8 communicated with the backflushing pipe 71, and flushing down the impurities attached to the lower surface of the filter screen 81 at the end part of the recycling pipe 8.

The implementation principle of the embodiment is as follows: the drought sand enters the cleaning box from the feed inlet 2, a valve at the position of a water inlet pipe 11 is opened, an external water source flows in, a stirring device 3 in the cleaning box 1 is started, a motor 32 drives a rotating shaft 31 to rotate, the rotating shaft 31 rotates to drive a stirring paddle blade 33 to rotate, thus stirring the drought sand and water is realized, impurities such as silt in the drought sand are washed away, part of water with impurities with small particle diameters such as silt pass through a filter cloth 41 and a filter plate 4 and enter a water receiving box 6, the drought sand stays on the filter cloth 41 and slides downwards along the inclined direction of the filter plate 4 under the drive of self gravity and the other part of water, and therefore the water and the drought sand reach a sand outlet pipe 12 and flow into a sand.

Water in the dry sand in the sand receiving box 5 can pass through the filter box 51 and enter the water receiving box 6 through the communicating pipe 53, the water pump 9 connected in the middle of the recovery pipe 61 is started to pump the water in the water receiving box 6 into the wastewater filter tower 7, and at the moment, the dry sand left in the sand receiving box 5 is cleaned.

Drain 74 is in the closed condition, the water liquid level that gets into waste water filter tower 7 rises gradually, reach second filter layer 73, filter, increase along with water, the liquid level continues to rise and reaches first filter layer 72, filter once more, increase along with water, when the liquid level rises gradually and reachs the mouth of pipe height of recycling pipe 8, the water pump 9 that recycling pipe 8 connects is opened, with water suction inlet tube 11, thereby flow into and wash case 1, reach the purpose with waste water cyclic utilization, in addition, water is when filtering through second filter layer 73, debris in the aquatic are filtered to second filter layer 73 surface, when debris accumulation is more, self weight makes debris fall down, then the tower wall gliding to drain 74 along the waste water filter tower 7 of slope.

And finally, during sewage discharge, opening a valve at the sewage discharge port 74, discharging the impurities downwards to the sewage discharge port 74 for one time, opening a valve of the backflushing pipe 71, allowing clean water to flow through the backflushing pipe 71 to reach the first filtering layer 72 and the second filtering layer 73, flushing down the impurities attached to the lower surface of the backflushing pipe, allowing the water in the backflushing pipe 71 to flow downwards through the recycling pipe 8 communicated with the backflushing pipe 71, and flushing down the impurities attached to the lower surface of the filter screen 81 at the end part of the recycling pipe 8.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
