Description

An integrated integrated water purification device

technical field

The utility model relates to an integrated integrated water purification device.

Background technique

At present, most rural areas and towns in my country do not have running water, and drinking water is generally drawn from groundwater or raw water from rivers and lakes. With the development of society and economy, drinking water sources such as groundwater, rivers and lakes are polluted to varying degrees, and drinking directly without treatment will endanger human health. Therefore, many rural areas and towns need to build water purification plants to meet people's demand for drinking water. However, most of the traditional domestic drinking water treatment facilities are civil pools, which not only occupy a large area, but also have a long construction period and difficult maintenance and management, which are no longer suitable for the construction requirements of modern water purification plants.

Contents of the invention

The purpose of the utility model is to provide an integrated integrated water purification device, which integrates the three process sections of flocculation, sedimentation and filtration, and solves the problems of large floor area, long construction period and difficult maintenance and management of traditional drinking water treatment facilities .

In order to achieve the above purpose, the utility model adopts the following technical solutions to achieve: an integrated integrated water purification device, including a grid flocculation area, an inclined tube sedimentation area, and a homogeneous filtration area, and the grid flocculation area is divided into 5 to 20 Each grid is close to a square, and the grids are connected by holes. In a grid, when the water inlet hole is on the top (or bottom), the water outlet hole is on the bottom (or top), and they are diagonally staggered. Due to the action of the orifice jet, the water flow sequence produces a swirling flow in each cell, which promotes the full contact of the tiny alum flowers in the raw water, increases the flocs, and is beneficial to improve the flocculation effect. Holes are opened along the wall of the pool on the partition between each grid in the grid flocculation area, and the positions of the orifices are arranged up and down, left and right, which can avoid short circuit of water flow and improve volume utilization. The orifice adopts rectangular or circular cross-section. There are mud discharge pipes passing through each grid for mud discharge and cleaning. A honeycomb-shaped inclined pipe is set in the inclined pipe sedimentation area to reduce the hydraulic radius and increase the wetted area of the water section of the pool. Therefore, when the water flow is at the same horizontal velocity, the Reynolds number can be greatly reduced, thereby reducing the storage and promoting sedimentation. . The inclined honeycomb packing in the inclined tube sedimentation area divides the original sedimentation area into a series of shallow sedimentation layers. The suspended solids and solids in the raw water or the floc alum flowers formed after adding coagulant gather on the surface of the inclined tube. It forms a thin mud layer and slides to the sludge area relying on gravity. The sludge discharge pipe adopts a perforated pipe structure and is installed along the bottom of the sludge area to facilitate the complete discharge of sludge. The supernatant gradually rises to the sump along the inclined pipe. , to complete the solid-liquid separation. A hexagonal honeycomb inclined pipe is installed in the inclined pipe sedimentation area, which is installed at an angle of 60° to the horizontal plane. The water inlet and distribution area adopts a perforated wall to rectify and distribute water to distribute the water evenly. There is also a flow blocking baffle at the gap between the inclined pipe and the pool wall. Prevent water short circuit. The homogeneous filtration area uses homogeneous quartz sand with a particle size of 0.9-1.2mm as the filter bed, and quartz sand with a particle size of 2-4mm as the supporting layer. The suspended solids in the raw water are removed through the adsorption, retention and filtration of the filter material. The homogeneous filtration area adopts the combination of air and water backwashing method. First, the air is washed alone, and then the air and water are simultaneously washed, and finally the water is washed alone. The specific process is: close the water inlet valve, but still part of the water flows into the filter to form surface sweeping. Open the intake valve, turn on the blower, the air enters the bottom of the filter evenly through the upper small hole of the air-water distribution channel, and is sprayed out by the long-handled filter head, scrubbing the impurities on the surface of the filter material and suspending them in the water, then washed by the surface cleaning water Then start the flushing water pump, open the flushing water valve, and the backwashing water also enters the air-water distribution channel, and the air and water flow into the water distribution area at the bottom of the filter through small holes and square holes respectively, and enter the filter evenly through the long handle filter head , the filter material is further washed, and the surface sweeping continues; the air flushing is stopped, and the water flushing is continued, and the surface sweeping continues, and finally all the impurities in the water are flushed into the drain tank and discharged through the backwashing sewage valve.

detailed description

The utility model is described in detail below through specific embodiments.

The water mixed with the agent enters the grid flocculation area (2) from the water inlet (1). The grid flocculation area is divided into 5-20 small cells, and the small cells are connected through water holes. When the water enters the grid flocculation area (2) In the first cell, the water enters from the bottom and the water comes out from the top. The water holes from the first cell to the second cell are diagonally staggered with the water inlet (1), and the water flow in the first cell generates a swirling flow due to the action of the orifice jet. . In the same way, the arrangement of the water holes between other small compartments is changed up and down, left and right, and gradually increases, so that the flow velocity gradient is from large to small, and the water flow produces more small eddies, which promotes the full contact of the tiny alum flowers in the raw water and increases the flocs. , which is beneficial to improve the flocculation effect. The last grid of water evenly enters the inclined tube sedimentation area (4) through the water distribution area (13).

The water distribution area (13) adopts perforated walls to rectify and distribute water, so that the water flow is evenly distributed, and the water flow evenly passes through the honeycomb inclined tube (6). The floc alum flowers gather into a thin mud layer on the surface of the honeycomb inclined tube (6), and slide to the sludge area by gravity, and pass through the sewage outlet (12). The sludge discharge pipe adopts a perforated pipe structure and is arranged along the bottom of the sludge area to facilitate the complete discharge of the sludge. The supernatant liquid gradually rises to the sump (5) along the inclined pipe to complete the solid-liquid separation. A blocking baffle is provided at the gap between the honeycomb inclined pipe (6) and the pool wall to prevent the short circuit of the water flow. The honeycomb inclined pipe (6) is installed at 60° with the horizontal plane.

The supernatant in the inclined tube sedimentation area (4) flows into the homogeneous filtration area (7) by gravity through the sump (5). The water flows through the homogeneous filter material from top to bottom. When the impurity particles in the water are large in size, the particles in the streamline will directly hit the surface of the filter material to intercept them; during the filtration process, the homogeneous filter area maintains a constant liquid position, the filtration speed remains unchanged, which is beneficial to improve the filtration efficiency. Finally, clear water is discharged from the water outlet (9).

The ability of the homogeneous filter area to intercept suspended solids has a certain limit. When it runs for a certain period of time or when the liquid level in the homogeneous filter area reaches the backwash level, the loss of water head on the surface of the filter layer increases, and the liquid level sensor starts the backwash water pump. The material is backwashed to remove the suspended solids accumulated in the filter layer after filtration and restore the filtration capacity of the filter layer.

Backwash gas production water combined with backwash, the water inlet valve is closed first, but some water still flows into the filter to form surface sweeping. Open the intake valve, turn on the blower, the air enters the bottom of the filter evenly through the upper hole of the air-water backwashing air pipe (11), and is sprayed out from the long-handled filter head to scrub the impurities on the surface of the filter material and suspend them in the water. The sweeping water is flushed into the drainage tank; then start the backwashing water pump, open the flushing water valve, and the backwashing water also enters the air-water distribution channel, and the air and water flow into the water distribution area at the bottom of the filter through the small hole and the square hole respectively, and pass through the long handle filter. The head evenly enters the filter tank, the filter material is further washed, and the surface sweeping continues; stop the air flushing, and the water flushing continues, and finally all the impurities in the water are flushed into the drainage tank and discharged through the backwash drain (10) . The water flow during backwashing is reversed and flows upward from the filter cap, causing turbulence in the filter layer. At this time, the adsorbed impurities are released and discharged through the backwash drain valve.
