Description

A building sewage treatment device

Technical field

The invention relates to the technical field of sewage treatment, and in particular to a construction sewage treatment device.

Background technique

In recent years, our country has paid more and more attention to environmental protection, and a very important aspect of environmental protection is sewage treatment. With the continuous advancement of our country's industrialization process, our country's construction industry has developed rapidly, and large and small construction sites abound, and During the operation of these construction sites, a large amount of construction sewage will be generated, which is accompanied by a large amount of solid waste. Therefore, special construction sewage treatment equipment is required to treat construction sewage.

Traditional building sewage treatment equipment generally uses a filter to filter out solid waste and then uses activated carbon to adsorb it, and finally discharges the treated water. However, there are many problems with traditional building sewage treatment equipment, as follows:

1. When traditional building sewage treatment equipment is filtered for the first time, solid waste often blocks the filter holes in the filter. When this happens, workers need to manually remove the solid waste in the filter or replace it with a new one. net, which greatly reduces the efficiency of filtration.

2. When the traditional building sewage treatment device is working, the water is often filtered through only one layer of filter screen and then discharged to the activated carbon plate for adsorption. The one-layer filter screen often filters the water uncleanly, and the water containing some solid garbage will When passing through the activated carbon plate, the solid waste adheres to the activated carbon plate, causing the adsorption effect of the activated carbon plate to become worse and the service life to be shortened.

3. When the traditional building sewage treatment device is working, it is discharged through simple filtration and activated carbon adsorption. The discharged water still contains some pathogenic bacteria and toxic substances, which will still cause pollution to the environment.

In view of this, in order to improve the above technical problems, the present invention provides a construction sewage treatment device, whose specific beneficial effects are as follows:

1. The present invention installs a cross-shaped filter plate and a flow meter on the housing. When the flow meter detects that the flow rate of water in the filter unit is less than the preset minimum value, it is proved that the solid garbage in the sewage blocks the filtration in the cross-shaped filter plate. hole, at this time, the control unit controls the rotation of the cross-shaped filter plate through the chain drive, so that the side with solid waste changes from horizontal to vertical, and the solid waste falls into the collection box in the filter unit through the gravity of itself, and some is attached to the The solid garbage on the surface of the cross-shaped filter plate will be washed by the water flow and fall on the No. 1 baffle in the next round of filtration, and fall into the collection box with the rotation of the No. 1 baffle; this can prevent the solid garbage from clogging. The font filter plate can also increase the service life of the cross-shaped filter plate.

2. In the present invention, a cross-shaped filter plate is installed on the housing, so that whenever sewage enters the filter unit, it will flow through two surfaces of the cross-shaped filter plate, which is equivalent to being filtered twice. After the sewage is filtered twice, the amount of solid garbage in the sewage is greatly reduced, which makes the filtration effect of the sewage treatment device better and also increases the service life of the activated carbon plate.

3. In the present invention, a disinfection unit is installed after the adsorption unit, and chlorine dioxide gas is introduced into it, so that the chlorine dioxide reacts with water to generate chloric acid. Chloric acid has strong oxidizing properties and can remove toxic substances and pathogens in the water. Germs are oxidized to achieve a disinfection effect on sewage.

The sewage passes through the cross-shaped filter plate 42 of the filter unit 4 and then enters the adsorption unit 8. The cross-shaped filter plate 42 filters out the solid garbage in the sewage. , since the solid garbage will block the filter holes of the cross-shaped filter plate 42 and cause the filtered water flow of the filter unit 4 to become smaller, the flow meter 47 located outside the housing 2 detects that the water flow rate in the filter unit 4 is less than the preset minimum value A After the signal, the control unit 3 controls the water pump 52 to stop pumping water;

Ten seconds later, the sewage in the filter unit 4 has completely flowed into the adsorption unit 8. At this time, the control unit 3 controls the collection motor 61 to rotate. The collection motor 61 drives the No. 2 rotating shaft 62 to rotate, and the No. 2 rotating shaft 62 rotates to drive the No. 1 gear. The plate 63 rotates downward, and after the No. 1 baffle 63 squeezes the switch 71 of the blocking unit 7, the blocking motor 72 in the blocking unit 7 starts to rotate. The blocking motor 72 drives the No. 3 rotating shaft 73 to rotate, and the No. 3 rotating shaft 73 drives the second rotating shaft 73 to rotate. The No. 1 baffle 74 rotates, and the No. 2 baffle 74 turns from the vertical state to the horizontal state. At the same time, the control unit 3 controls the rotation of the filter motor 43. The filter motor 43 drives the No. 1 sprocket 44 to rotate, and the No. 1 sprocket 44 drives the No. 1 sprocket 44 through the chain 46. The No. 2 sprocket 45 rotates. The No. 2 sprocket 45 drives the No. 1 rotating shaft 41 to rotate. The No. 1 rotating shaft 41 drives the cross-shaped filter plate 42 to rotate. When the cross-shaped filter plate 42 rotates 90°, it stops rotating. At this time, the cross-shaped filter plate 42 rotates. The side of the filter plate 42 with solid garbage is in a vertical state, and the solid garbage will fall into the collection box 64 due to gravity; when the solid garbage is too large, it usually will not block the filter holes in the cross-shaped filter plate 42, but it will The font filter plate 42 will bear a gravity greater than its bearing capacity. At this time, the overload protector detects that the torque of the No. 1 rotating shaft exceeds the set value and transmits the information to the control unit 3. The control unit 3 controls the No. 1 gear in the collection unit. The plate rotates, and at the same time, the control unit 3 controls the rotation of the second baffle, so that large pieces of garbage quickly fall into the collection box to avoid damaging the cross-shaped filter plate 42.

Ten seconds later, the solid garbage has basically finished falling, and the solid garbage remaining on the surface of the cross-shaped filter plate 42 will fall to the No. 1 baffle 63 due to the next flush of water flow, along with the No. 1 baffle 63 falling. Once rotated, it falls into the collection box 64; at this time, the control unit 3 controls the collection motor 61 to reverse, the collection motor 61 drives the No. 2 rotating shaft 62 to rotate, and the No. 2 rotating shaft 62 rotates to drive the No. 1 baffle 63 to rotate upward. The switch 71 in the blocking unit 7 is no longer squeezed, and the blocking motor 72 begins to flip. The blocking motor 72 drives the No. 3 rotating shaft 73 to rotate, and the No. 3 rotating shaft 73 drives the No. 2 baffle 74 to rotate, and the No. 2 baffle 74 moves from horizontal to horizontal. The state turns to the vertical state. At this time, the blocking unit 7 blocks the rotation of the filter unit and starts the next filtration; after the water filtered by the filter unit 4 is adsorbed by the three-layer activated carbon plate 82 in the adsorption unit 8, the particulate matter in the water and The colloidal substances have been adsorbed, and the adsorbed water enters the disinfection unit 9 through the water outlet. The staff will regularly and quantitatively put chlorine dioxide gas into the feed port. After the chlorine dioxide oxidizes the toxic substances in the water, the sewage will The water that has been treated to meet dischargeable standards is discharged in the disinfection unit 9 .
