Examples

Referring to fig. 1, fig. 1 is a schematic longitudinal sectional view of a sewage integrated processor 100 according to the present embodiment, the sewage integrated processor 100 includes a barrel 110 and a central cylinder 150, wherein the barrel 110 has a receiving cavity, and the central cylinder 150 divides the receiving cavity into a water outlet area 112 and a sewage treatment cavity 152. This sewage treatment chamber 152 is provided with dross collecting vat 154 and a plurality of aeration pieces 160, and aeration pieces 160 attach to the pollutant in the sewage as the carrier through producing the micro-bubble to make the buoyancy of pollutant be greater than gravity, then detach the pollutant of come-up through dross collecting vat 154, reach preliminary water purification's effect.

In this embodiment, the central barrel 150 is configured to divide the receiving cavity into the waste water treatment chamber 152 and the water outlet region 112, so as to ensure that the water in the water outlet region 112 is not affected by the waste water treatment chamber 152. Because the sewage treatment cavity 152 needs to be added with medicament and aerated, the treated sewage enters the water outlet area 112 from the bottom of the central cylinder 150 and is discharged from the upper end of the water outlet area 112, the primary treatment effect is ensured, and the sewage treatment cavity 152 and the water outlet area 112 are not influenced mutually. In this embodiment, the water outlet region 112 is provided with a central tube fixing member 124, one end of the central tube fixing member 124 is fixedly connected to the outer wall of the central tube 150, and the other end of the central tube fixing member 124 is fixedly connected to the inner wall of the barrel body 110, so as to fixedly support the central tube 150. In addition, in this embodiment, the length direction of the central tube fixing member 124 is perpendicular to the wall surface of the central tube 150, so that the material consumption of the central tube fixing member 124 can be reduced, the cost can be reduced, and the fixing effect is better. In other embodiments, the length direction of the central tube fixing member 124 may be set at other angles on the wall surface of the central tube 150 to achieve the desired fixing effect. In this embodiment, the center tube fixing members 124 are disposed at both sides of the center tube 150 in a pair manner, thereby enhancing the stability of the center tube 150. And all set up a pair of center section of thick bamboo mounting 124 in the upper and lower position of a center section of thick bamboo 150, guarantee that center section of thick bamboo 150's stability is higher, avoid it to receive the effect of sewage, move about from top to bottom, influence sewage treatment effect. In this embodiment, the spacing distance between the central tube fixing members 124 is 1.5m, which can reduce the investment cost while ensuring the stability of the central tube 150. Of course, in other embodiments, the central cylinder fixing members 124 may be arranged in different forms or numbers, for example, the central cylinder fixing members 124 are arranged in a staggered manner, that is, the central cylinder fixing members 124 on both sides of the central cylinder 150 are not on a plane, and the stabilizing effect may also be achieved.

In this embodiment, the sewage treatment chamber 152 is provided with a scum collector and aerator 160, the scum collector being provided with a slag outlet 156, the slag outlet 156 being connected to one end of a slag pipe 158, the other end of the slag pipe 158 extending outside the tub 110, as shown in fig. 1. Moreover, the width of the upper end collection portion (i.e. the portion with the rectangular cross section) of the scum collection tank 154 is greater than the width of the lower end slag discharge portion, so that the scum collection is facilitated, the scum is prevented from being accumulated in the sediment at the bottom of the scum collection tank 154, and the scum is not easy to clean and discharge, thereby reducing the use performance. In addition, the other end of the slag pipe 158 extends directly to the outside of the tub 110, which facilitates further collection and disposal of the dross. It should be noted that in this embodiment, the scum collecting groove 154 is not required to be further provided with a scum collecting groove fixing member 155, one end of the scum collecting groove fixing member 155 is fixedly connected to the outer wall of the scum collecting groove 154, and the other end of the scum collecting groove 154 is fixedly connected to the inner wall of the central tube 150, so that the stability of the scum fixing groove is enhanced. In addition, the scum collecting tank fixing part 155 can also be used as a support carrier of the air pipeline 162, so that the air pipeline 162 is reasonably arranged, the aeration parts 160 are reasonably distributed, and the sewage treatment effect is improved. In this embodiment, the sewage treatment chamber 152 is provided with four aeration members 160, and the four aeration members 160 are uniformly distributed in the circumferential direction of the central cylinder 150, as shown in fig. 2, fig. 2 is a top view of the sewage comprehensive processor 100 provided in this embodiment. Specifically, the aeration member 160 is communicated with an air pipe 162, and the air pipe 162 can continuously supply the required amount of air to the aeration member 160, so that the aeration member 160 can continuously generate micro-bubbles during the operation of the integrated sewage treatment unit 100 to attach pollutants in the sewage, thereby achieving an air flotation effect. And evenly distributed can make in the sewage pollutant get rid of the effect better in a central section of thick bamboo 150 circumference, avoids appearing the inside sewage treatment effect of a central section of thick bamboo 150 inhomogeneous, influences holistic sewage treatment effect. In addition, the aeration pressure of a single aeration piece 160 can be effectively reduced by the uniform distribution of the four aeration pieces 160, so that the expected primary treatment effect is achieved, the service life of the aeration piece 160 can be prolonged, and the setting is more reasonable. In other embodiments, 1, 2, 3 or more aeration members 160 may be disposed in the sewage treatment chamber 152, and the primary sewage purification effect can be achieved as well.

In this embodiment, still include the dosing pipe 114, this dosing pipe 114 adds the medicine mouth and sets up in the top of a central section of thick bamboo 150 for the medicament can be because the action of gravity of self and diffusion more evenly distributed in the sewage, thereby lets the large granule in the sewage and colloidal pollutant all can participate in the reaction, deposits in the heavy end collection portion of staving 110. When the chemical feeding pipe 114 is disposed in the middle or lower section of the central cylinder 150, the chemical is more likely to further diffuse downward, and the upward diffusion capability is smaller, so that the pollutants in the sewage at the upper section of the central cylinder 150 cannot rapidly participate in the flocculation reaction, and the effect of removing the pollutants by flocculation precipitation cannot be achieved. In addition, the middle pipe body part of the dosing port of the dosing pipe 114 and the dosing port (the external dosing position of the barrel body 110) is arranged inside the barrel body 110, so that the pipe body can be effectively prevented from being influenced by environmental factors, the aging speed is high, the service life is short, and the equipment maintenance cost is increased.

In this embodiment, the upper end of the inner wall of the barrel 110 is further provided with an effluent weir 120, the bottom of the effluent weir 120 is provided with a water outlet 121, the water outlet 121 is connected with one end of a water outlet pipe 122, and the other end of the water outlet pipe 122 extends to the outside of the barrel 110. The weir 120 is disposed at the upper end of the inner wall of the barrel 110, and the height of the weir 120 is lower than the height of the top opening of the central tube 150 relative to the bottom of the support 128 of the barrel 110. Specifically, in this embodiment, the height of the effluent weir 120 is 7.8m, and the height of the top end of the central cylinder 150 is 8.5m, so that the sewage in the sewage treatment chamber 152 does not easily overflow to the effluent area 112, and the water treatment effect is ensured. Moreover, when the setting height of the effluent weir 120 is higher, the effluent quality can be further ensured to reach the primary treatment effect, because when the setting height of the effluent weir 120 is lower, the partial sediment in the barrel is not completely deposited to the sediment collection bottom, and the effluent flows out along with the effluent flow easily, so that the treatment effect is influenced. It should be noted that, in the present embodiment, the effluent weir 120 is circumferentially disposed along the inner wall of the barrel 110, and one side of the effluent weir, which is away from the inner wall of the barrel 110, is serrated (a single serration is triangular), which is beneficial to further intercepting light large-particle pollutants and ensuring the effluent quality. Of course, in other embodiments, the shape of the weir 120 can be other shapes, such as a semi-circular shape or a trapezoid shape of the weir 120 (single sawtooth) on the side away from the inner wall of the barrel 110.

In this embodiment, the upper end of the central cylinder 150 is further provided with a water inlet pipe 126, as shown in fig. 3, and fig. 3 is a schematic left-view longitudinal section view of the sewage treatment device 100 according to the embodiment of the present invention. The reason why the water inlet pipe 126 is installed at the upper end of the central cylinder 150 is that when the height of the water inlet pipe 126 is set to be low, the newly added sewage cannot completely pass through the whole sewage treatment process of the integrated sewage treatment unit 100, so that on one hand, the sewage treatment effect is poor, and on the other hand, the sediment which is sinking or has sunk to the lower part can be re-floated, thereby increasing the impurities in the effluent. Moreover, when the position of the pipe orifice of the water inlet pipe 126 is lower, untreated sewage can be mixed with the treated sewage, the removal effect of COD, total nitrogen and total phosphorus in the sewage is greatly reduced, the treatment efficiency is reduced, and the cost is increased.

In this embodiment, the tub 110 is further provided with a sediment collection portion 116. This deposit collection portion 116 is the inverted cone for deposit can rely on self action of gravity to slide down along the inclined wall face, avoid the bottom surface to deposit and accumulate gradually, be difficult for cleaing away also difficult discharge, increase sewage integrated processor 100's maintenance cost. In addition, the precipitates deposited on the wall surface increase in weight as the precipitates increase, so that the precipitates can be more rapidly discharged outside the tub 110 for further treatment, thereby shortening the entire primary treatment period. In this embodiment, the bottom of the barrel 110 is further provided with a support 128. The top end of the support 128 is fixedly connected to the top end of the sedimentation collecting part 116, and the bottom end of the support 128 is used for supporting the whole integrated sewage treatment unit 100, so that the integrated sewage treatment unit 100 can be stably placed on the ground or other sewage treatment areas. This support 128 comprises 3 supports, and has the horizontal pole setting (be the one end and the support fixed connection of horizontal pole promptly, the other end of horizontal pole and sediment collection portion 116 bottom fixed connection) between single support and sediment collection portion 116 bottom, strengthens this sewage integrated processor 100's stability greatly, avoids it to receive external effort and takes place the slope and overturn. It should be noted here that, in other embodiments, a barrel cover may be further disposed at the upper end of the barrel body 110, and the barrel cover is detachably connected to the barrel body 110 and disposed in an openable and closable manner, so that the peculiar smell of the sewage can be effectively prevented from diffusing to a remote place, even diffusing to a residential area, and affecting the living environment of people. In this embodiment, the bottom of the support 128 is used as a reference, the height of the integrated sewage treatment device 100 is 8.5m, the height of the outlet weir 120 is 7.8m, the height of the uppermost central tube fixing part 124 is 7.0m, the height of the lowermost central tube fixing part 150 is 4.0m, the height of the bottom surface of the inverted cone of the sedimentation collection part 116 is 2.5m, the diameter of the barrel body 110 is 3m, and the diameter of the central tube 150 is 1.5 m. It should be noted that the integrated wastewater treatment system 100 can also meet the requirements if it is desired to remove scum, oil or flocculate alone, for example, only the flocculation can be achieved by using the dosing tube 114 alone.

Specifically, in use, sewage is fed from the upper end of the central cylinder 150 through the inlet pipe 126, and when the sewage submerges the aeration member 160, aeration is performed such that the aeration member 160 operates to generate a large amount of fine bubbles, and a part of contaminants (including oil and light contaminants) in the sewage floats up to the surface of the sewage on the basis of the bubbles, and when the amount of scum is accumulated to the height of the scum collecting tank 154, the floating contaminants can be collected by the scum collecting tank 154 and discharged through the slag outlet 156. When the chemical agent enters the sewage treatment chamber 152 through the chemical adding pipe 114, large particles and colloidal contaminants in the sewage are polymerized into particles with larger weight by the chemical agent, and then are precipitated to the precipitation collecting part 116 and discharged from the sludge discharge port 118. The treated sewage flows out from the bottom of the central cylinder 150 together with the sediment, the sediment continuously settles downwards due to the action of gravity, the treated sewage enters the effluent area 112, and the sediment continuously settles downwards in the process that the treated sewage gradually flows to the effluent weir 120, so that the treatment effect of effluent is ensured. The height and shape of the weir 120 further ensure that the sediment sinks into the sediment trap 116 and is prevented from flowing into the outlet 121 along with the water flow.

The working principle of the integrated wastewater treatment unit 100 is as follows:

the integrated sewage treatment apparatus 100 includes a tub 110 and a central tub 150, wherein the central tub 150 is provided with a scum collecting tank 154 and a plurality of aeration members 160. The aeration member 160 is connected to an air pipe 162, and can remove contaminants (including oil and impurities) by generating fine bubbles as carriers to attach the contaminants to the sewage and floating them with a buoyancy greater than gravity, and then removing the floating contaminants by the dross collecting groove 154. In addition, the integrated sewage treatment unit 100 can also precipitate other pollutants by flocculation and then remove the pollutants through a sludge discharge pipe. Therefore, the integrated sewage treatment device 100 can remove oil and scum simultaneously, flocculate and precipitate large particles and colloidal pollutants, has simple and feasible operation procedure, saves manpower and equipment investment cost, and has higher economic benefit.

To sum up, the utility model provides a sewage integrated processor 100 can get rid of oil, light pollutant, large granule and the gelatinous pollutant in the sewage simultaneously, has simplified the sewage treatment procedure effectively, reduces the sewage treatment cost, and the practicality is strong. In addition, the sewage comprehensive processor 100 reduces COD, total nitrogen and total phosphorus of the sewage to a certain extent, relieves the pressure of subsequent secondary treatment, and is beneficial to the effluent of the sewage to reach the sewage discharge standard.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art.
