Examples

Referring to fig. 1, the present embodiment provides a graded continuous filtration apparatus for sewage in villages and towns (hereinafter referred to as "continuous filtration apparatus"), which includes a filtration mechanism 1, an accommodation mechanism 2, a differential pressure mechanism 3 and a water supplement mechanism 4. The water replenishing mechanism 4 receives sewage from the villages and towns and conveys the sewage into the housing mechanism 2. The pressure difference mechanism 3 forms a pressure difference in the containing mechanism 2, and causes the sewage entering the containing mechanism 2 to continue flowing forwards. The sewage passes through the filter mechanism 1 during the flowing process and is filtered by the filter mechanism 1 under the restriction of the containing mechanism 2.

In another embodiment of the present application, the continuous filtration device may also be used to treat wastewater originating from cities, factories, etc.

The accommodating mechanism 2 includes a housing 21, the housing 21 is cylindrical, and the cross section thereof includes, but is not limited to, a circle, a rectangle, a regular polygon, and the like, the housing 21 is made of stainless steel, and the housing 21 is disposed in a vertical direction. The filter mechanism 1 is arranged in the shell 21, the pressure difference mechanism 3 is arranged on the shell 21, and the water replenishing mechanism 4 is connected with the shell 21.

The side wall of the top of the shell 21 is provided with a water inlet 211, the water inlet 211 is located above the filtering mechanism 1, and the bottom of the shell 21 is provided with a water outlet 212. After entering the interior of the housing 21 through the water inlet 211, the sewage flows through the filtering mechanism 1 from top to bottom, is filtered by the filtering mechanism 1, and is discharged through the water outlet 212.

In the above process, the differential pressure mechanism 3 forms an additional differential pressure at the two ends of the housing 21, and the gravity borne by the sewage itself is matched to drive the sewage to flow through the filtering mechanism 1 rapidly, so that the sewage treatment efficiency is improved. Along with the sewage above the filtering mechanism 1 is gradually consumed, the water supplementing mechanism 4 supplements the sewage to the inside of the shell 21 again through the water inlet 211, and then continues filtering, so that the continuity of the sewage treatment process can be ensured.

Specifically, the water replenishing mechanism 4 is constituted by a water storage tank 41, a water replenishing pipe 42, and the like.

The sewage to be treated is stored in the storage tank 41 and the preliminary sedimentation process is completed in the storage tank 41, so that a part of large particles, suspended matter and trash contaminants are separated from water.

The water replenishing pipe 42 is connected with a water pump 43 and a one-way valve 44. The water pump 43 outputs power to convey the sewage in the reservoir 41 into the housing 21, and is turned off after a sufficient amount of sewage is conveyed. The check valve 44 is disposed between the water pump 43 and the water inlet 211 to allow the sewage to flow from the reservoir 41 to the housing 21 when the water pump 43 is turned on, while preventing the sewage in the housing 21 from flowing back to the water replenishing pipe 42 when the water pump 43 is turned off.

Be equipped with first jar of body 22 in the casing 21, first jar of body 22 passes through modes such as bolted connection or joint detachably and sets up at casing 21 top, and first jar of body 22 bottom is connected with filtering mechanism 1 promptly. The first tank 22 is cylindrical, and the axis of the first tank 22 coincides with the axis of the housing 21.

The water inlet 211 is communicated with the first tank 22, and the water replenishing mechanism 4 directly replenishes the sewage into the first tank 22.

The differential pressure mechanism 3 can form an extra pressure difference at the two ends of the housing 21 by pressurizing the top end of the housing 21, and can also form an extra pressure difference at the two ends of the housing 21 by depressurizing the bottom end of the housing 21, so that the speed of sewage flowing through the filtering mechanism 1 can be increased.

In this embodiment, the pressure difference is created by means of pressurization. The differential pressure mechanism 3 is embodied as an electric push rod, and the electric push rod acts on the first tank 22.

The electric push rod is arranged on the top end face of the shell 21, and the piston of the electric push rod is positioned in the first tank 22 and matched with the first tank 22.

The electric push rod in the initial state is positioned at the top of the first tank 22, and at this time, the water pump 43 is closed after supplying a sufficient amount of sewage into the first tank 22, and the sewage fills the area inside the first tank 22 below the piston of the electric push rod.

Due to the existence of the check valve 44, the sewage cannot flow back into the water replenishing pipeline 42 and can only leave the interior of the first tank 22 through the joint of the first tank 22 and the filtering mechanism 1. When the piston of electric putter is pushed down, sewage is compelled to flow into filtering mechanism 1, and its speed is far greater than the speed that sewage oozed down naturally under the action of gravity to can keep steadily, thereby improve filtration efficiency greatly.

When the piston of the electric push rod moves to the water inlet 211, the pressing is stopped, and the water supplementing pipeline 42 is always communicated with the inside of the first tank 22. Next, the piston of the electric push rod starts to move upwards and return, a space for containing the sewage is vacated in the first tank 22, and the water pump 43 is started to inject the sewage into the first tank 22.

After the piston of the electric push rod moves up to the end of the stroke, the water pump 43 is turned off, and the above process is repeated to continuously treat the sewage.

In the above process, the area through which the piston of the electric push rod moves from the initial position to the water inlet 211 is the effective volume of the first tank 22 to the sewage. Therefore, the water inlet 211 is communicated with the bottom of the first tank 22 to utilize the space inside the first tank 22 as much as possible, and simultaneously, the lifting frequency of the electric push rod piston is reduced, and the sewage treatment efficiency is further improved.

In the present embodiment, the filter mechanism 1 is composed of a first filter layer 11, a second filter layer 12, and a third filter layer 13. The first filter layer 11, the second filter layer 12 and the third filter layer 13 are sequentially arranged from top to bottom in the shell 21, and are respectively filled with different filter materials to perform classified filtration on sewage.

Correspondingly, a second tank 23, a third tank 24 and a fourth tank 25 are arranged in the shell 21, the second tank 23 is positioned between the first filter layer 11 and the second filter layer 12, the third tank 24 is positioned between the second filter layer 12 and the third filter layer 13, and the fourth tank 25 is positioned below the third filter layer 13. Similar to the first tank 22, the second tank 23, the third tank 24, and the fourth tank 25 are also cylindrical and are connected to the housing 21 by means of bolts or snaps.

The first tank 22, the first filter layer 11, the second tank 23, the second filter layer 12, the third tank 24, the third filter layer 13 and the fourth tank 25 are connected in sequence, and structures such as sealing gaskets are arranged at the joints to ensure sufficient sealing performance.

The water outlet 212 is funnel-shaped and is communicated with the bottom end of the fourth tank 25. After entering the first tank 22 from the water inlet 211, the sewage can only flow through the first tank 22, the first filter layer 11, the second tank 23, the second filter layer 12, the third tank 24, the third filter layer 13 and the fourth tank 25 in sequence, and finally is discharged from the water outlet 212.

In the initial stage of filtration, the sewage pump 43 pumps the sewage into the first tank 22, and then the sewage is pushed down by the piston of the electric push rod to generate thrust, so that the sewage in the first tank 22 passes through the first filter layer 11.

After the sewage enters the second tank 23 and fills the second tank 23, the thrust of the electric push rod can act on the sewage in the second tank 23, and the part of sewage passes through the second filter layer 12 under the action of gravity and the thrust of the electric push rod and enters the third tank 24.

Similarly, when the third tank 24 is filled with sewage, the thrust of the electric push rod can act on the sewage in the third tank 24, and the sewage passes through the third filter layer 13 under the action of gravity and the thrust of the electric push rod, enters the fourth tank 25 and is discharged through the water outlet 212.

Thereafter, the second tank 23 and the third tank 24 are always filled with sewage until the filtration is finished. When the filtration is finished, the sewage in the first tank 22 is completely pressed into the first filter layer 11 by the piston of the electric push rod, and the sewage in the first filter layer 11, the second tank 23, the second filter layer 12, the third tank 24 and the third filter layer 13 naturally seeps downwards under the action of gravity.

In the working process, as the first tank 22, the first filter layer 11, the second tank 23, the second filter layer 12, the third tank 24 and the third filter layer 13 are connected in sequence, and the joints have better sealing performance, the linkage pressure application in the first tank 22, the second tank 23 and the third tank 24 can be realized through an electric push rod, so that the sewage can rapidly and uniformly pass through the first filter layer 11, the second filter layer 12 and the third filter layer 13.

Specifically, the first filter layer 11 is filled with straw and asbestos pad. When the sewage passes through the first filter layer 11, all or most of large-sized solid waste and viscous contaminants in the sewage are removed by adsorption.

Specifically, the second filter layer 12 is filled with straw, macroporous activated carbon, montmorillonite and sepiolite. When the sewage passes through the second filter layer 12, all or most of the organic pollutants in the sewage are removed by adsorption. In addition, due to the existence of the macroporous activated carbon, deodorization and decoloration of sewage can be realized.

Specifically, the third filter layer 13 is filled with ion exchange-adsorption resin and activated carbon. When the sewage passes through the third filtering layer 13, all or most of the heavy metal ions in the sewage are adsorbed and removed.

The first filter layer 11, the second filter layer 12 and the third filter layer 13 respectively remove impurities with different sizes in sewage, large-particle solid waste and sticky pollutant are not easy to be generated to block the large-pore activated carbon, montmorillonite and sepiolite, and large-particle solid waste, sticky pollutant and organic pollutant are not easy to be generated to block the ion exchange-adsorption resin and the activated carbon, so that the adsorption capacity of the large-pore activated carbon, the montmorillonite, the sepiolite ion exchange-adsorption resin and the activated carbon is fully utilized, and the service life of the filter mechanism 1 is greatly prolonged.

The first filter layer 11 is cylindrical, the diameter of the first filter layer is 10-25cm, the length of the first filter layer is 12-50cm, and the shell of the first filter layer 11 is made of stainless steel. In addition, the top end of the first filter layer 11 is detachably connected with the first tank 22 through a buckle or a hinge, and the bottom end of the first filter layer 11 is detachably connected with the second tank 23 through a buckle or a hinge.

The second filter layer 12 is cylindrical, the diameter of the second filter layer is 10-25cm, the length of the second filter layer is 12-50cm, and the shell of the second filter layer 12 is made of stainless steel. In addition, the top end of the second filter layer 12 is detachably connected with the second tank 23 through a buckle or a hinge, and the bottom end of the second filter layer 12 is also detachably connected with the third tank 24 through a buckle or a hinge.

The third filter layer 13 is cylindrical, the diameter of the third filter layer is 10-25cm, the length of the third filter layer is 12-50cm, and the shell of the third filter layer 13 is made of stainless steel. In addition, the top end of the third filter layer 13 is detachably connected with the third tank 24 through a buckle or a hinge, and the bottom end of the third filter layer 13 is also detachably connected with the fourth tank 25 through a buckle or a hinge.

When the filler in the first filter layer 11, the second filter layer 12 and the third filter layer 13 is saturated, the filler can be replaced by taking out the first tank 22, the first filter layer 11, the second tank 23, the second filter layer 12, the third tank 24, the third filter layer 13 and the fourth tank 25 from the shell 21, and then quickly detaching the first filter layer 11, the second filter layer 12 and the third filter layer 13 from the first tank 22, the second tank 23, the third tank 24 and the fourth tank 25 respectively. The disassembly and the assembly are convenient, and the continuity and the high efficiency of the sewage treatment process are ensured.

The sewage generated by villages and small towns is firstly led into the water storage tank 41, and the preliminary sedimentation is completed in the water storage tank 41. The pump 43 is then turned on to pump the wastewater into the first tank 22. The sewage is accelerated to pass through the first filter layer 11, the second tank 23, the second filter layer 12, the third tank 24 and the third filter layer 13 by utilizing the electric push rod for pressurization, and the filtering treatment of the sewage is completed. The sewage finally enters the fourth tank 25 and is discharged from the water outlet 212.
