Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1, the utility model provides a technical solution: an urban sewage filtering tank comprises a tank body 1, wherein a first permeable layer 2 and a second permeable layer 3 are filled in an inner cavity of the tank body 1, the first permeable layer 2 is positioned on one side below the second permeable layer 3, a water purification chamber 4 is arranged at the bottom of the right side of the inner cavity of the tank body 1, the outside of the water purification chamber 4 is separated from the first permeable layer 2 through a first filter screen 5, an activated carbon adsorption layer 6 is further arranged between the water purification chamber 4 and the first filter screen 5, the tank body 1 is positioned on the second permeable layer 3 and communicated with a sludge chamber 7 at the same horizontal position, a second filter screen 8 is further arranged at the upper part of the second permeable layer 3 in the inner cavity of the tank body 1, the second filter screen 8 is of an arc-shaped structure with the middle part arched upwards, floating object containing boxes 9 are communicated with the same horizontal position of the second filter screen 8 at the left side and the right, the filler of the first permeable layer 2 is fine sand, the filler of the second permeable layer 3 is cobblestones, two opposite inclined planes 10 are arranged at the top of the second permeable layer 3, one side of each inclined plane 10 close to each other is higher than the opposite side of each inclined plane, the second permeable layer 3 is positioned at the lower side of each inclined plane 10 and communicated with the sludge chamber 7, a water outlet 11 is arranged at the bottom of the right side of the tank body 1, the water purification chamber 4 is communicated with the water outlet 11, when the filter is used, sewage to be filtered is injected through the upper part of the tank body 1, the floating objects of the sewage are filtered through the second filter screen 8, larger particles and floating objects can be effectively filtered, the sewage enters the upper part of the second permeable layer 3, because the two opposite inclined planes 10 are arranged at the top of the second permeable layer 3, the height of the inclined planes 10 close to each other is higher than the, simultaneously sewage carries out the osmotic filtration through second permeable formation 3, and the sewage of staying at mud room 8 also can filter through second permeable formation 3, and after second permeable formation 3 filters, through the further osmotic filtration of first permeable formation 2, the bottom of the pool is stayed to the clear water after the filtration, and the clear water adsorbs through second filter screen 8 and active carbon adsorption layer 6, then stays inside water purification room 4, and wherein the fine sand that first permeable formation 2 was avoided to second filter screen 8 enters into in water purification room 4. When needs extraction clear water, can extract through delivery port 11, along with the decline of water level, inside floater and great granule can fall floater containing box 9 along with the water level, when needs clear up mud room 7 and floater containing box 9, only need open mud room 7 and floater containing box 9, then the clearance can.
The working principle is as follows: when in use, sewage to be filtered is injected through the upper part of the tank body 1, floaters of the sewage are filtered through the second filter screen 8, larger particles and floaters can be effectively filtered and enter the sewage at the upper part of the second permeable layer 3, because the top of the second permeable layer 3 is provided with two opposite inclined surfaces 10, the height of the inclined surfaces 10 close to each other is larger than that of the inclined surfaces 10 on the opposite side, silt in sewage flows into the sludge chamber 8 through sedimentation, meanwhile, the sewage is subjected to osmotic filtration through the second permeable layer 3, the sewage left in the sludge chamber 8 is also filtered through the second permeable layer 3, after the sewage is filtered through the second permeable layer 3, further permeating and filtering through the first permeating layer 2, leaving the filtered clean water at the bottom of the tank, adsorbing the clean water through the second filter screen 8 and the active carbon adsorbing layer 6, and then left inside the clean water chamber 4, wherein the second sieve 8 prevents fine sand of the first permeable layer 2 from entering the clean water chamber 4. When needs extraction clear water, can extract through delivery port 11, along with the decline of water level, inside floater and great granule can fall floater containing box 9 along with the water level, when needs clear up mud room 7 and floater containing box 9, only need open mud room 7 and floater containing box 9, then the clearance can.
