The technical scheme of the invention will be further described with reference to the examples and the accompanying drawings.
Referring to fig. 1 to 4, the embodiment of the invention provides a modular hospital sewage treatment station, which comprises a plurality of treatment tanks arranged in a row, wherein each treatment tank comprises a concrete foundation slab 1a and a plurality of side walls 1b, the side walls 1b are fixedly arranged on the concrete foundation slab 1a and are connected with the concrete foundation slab 1a in a surrounding manner, each side wall 1b comprises a plurality of sequentially piled brickwork 111, a hollow part (not shown) is arranged in each brickwork 111, reinforcing steel bars (not shown) are placed in the hollow parts, filling concrete 112 is filled in the hollow parts, and the filling concrete 112 is used for fixing the reinforcing steel bars in the hollow parts.
Since most of the side walls 1b of the hospital sewage treatment tanks are generally formed by stacking, splicing and combining a plurality of bricks at present. However, as the bricks are generally solid, the bearing capacity of the bricks is limited, and the shearing resistance and the bending resistance of the bricks are not ideal, so that the impact load resistance of the wall of the sewage treatment pond is poor, the side wall 1b of the sewage treatment pond cannot be built too high, and the sewage treatment pond has the conditions of overlarge area and overlarge volume. The masonry 111 adopted by the side wall 1b of the hospital sewage treatment station provided by the invention has the advantages that the masonry 111 is of a hollow structure with a hollow part, the steel bars and the core concrete 112 can be placed in the hollow part of the masonry 111, and the structural strength of the masonry 111 can be enhanced by utilizing the steel bars and the core concrete 112, so that the strength and the rigidity of the side wall 1b of the treatment water tank can be enhanced, the volume of the treatment water tank can be increased by increasing the height of the side wall 1b, the occupied area of the treatment station can be reduced, the space utilization rate of the treatment station can be improved, and the comprehensive use benefit of the land of the treatment station can be improved.
In addition, the masonry 111 provided by the invention adopts a modularized design, each module masonry 111 can be prefabricated in a factory in advance, the size of the masonry 111 can be determined according to the size of a treatment water tank of a hospital sewage treatment station, for example, the size of the masonry 111 can be 400mm x 300mm x 170mm, 400mm x 170mm or 400mm x 180mm, and the like, and then the manufactured masonry 111 is transported to the site for rapid assembly, so that the construction period and construction efficiency of the treatment station can be greatly reduced, the construction efficiency of the treatment station can be improved, the construction cost of the treatment station can be saved, the process combination is flexible, and the application range is wide.
Wherein, the modular design of the treatment pool means: the design of the brickwork 111 of the side wall 1b of the treatment water tank adopts a modularized design, and each module brickwork 111 has relative independence, interchangeability and universality, thereby being beneficial to realizing popularization of hospital sewage treatment stations. That is, the modular masonry 111 can realize the exchange between the modular masonry 111 and can also meet the requirements of treatment ponds of different specifications to meet the requirements of a treatment station without hospital sewage. In addition, since the shape, structure and specification of each modular masonry 111 constituting the side wall 1b of the treatment tank are generally standardized, the modular masonry 111 can be manufactured in a specialized manner by a separate department of a factory or a dedicated factory, thereby facilitating mass production of the modular masonry 111.
In this embodiment, in order to improve the shearing resistance, tensile strength and connection between the side walls 1b of the masonry 111, a plurality of constructional columns 3 are arranged on the concrete foundation slab 1a, and the constructional columns 3 are embedded in the side walls 1b of the treatment pool, which is beneficial to strengthening the overall strength of the side walls 1b, so that the side walls 1b are not easy to collapse, and the use safety and the service life of the treatment pool are effectively improved.
Specifically, since the constructional column 3 is embedded in the side wall 1b of the treatment tank, and the construction of the treatment tank is to cast concrete to form the constructional column 3 and then to pile up the masonry 111, and since most of the treatment tanks are generally square (such as cubes, cuboid, etc.), in order to make the masonry 111 at the junction of the two side walls 1b seamless with the constructional column 3 when the masonry 111 is piled up, a concrete module of a special shape can be used at the junction of the two side walls 1b, such as: 250-300mm standard block type, 400-500mm standard block type, 300mm right angle block type, 400mm right angle block type, etc., thereby improving the strength of the side wall 1b of the treatment tank.
For example: when the area of the treatment pool is 3m by 3m, a 300mm right-angle block type can be adopted at the intersection of the two side walls 1 b. When the area of the treatment pool is 4m by 4m, a 400mm right-angle block type can be adopted at the intersection of the two side walls 1 b. It will be appreciated that in other embodiments, the type of concrete modules that may be used at the intersection of the side walls 1b may also be dependent on the actual size of the area of the treatment basin, for example 250mm square blocks or the like.
Further, in order to improve the load-bearing capacity of the treatment tank, the treatment tank further includes a plurality of ring beams (not shown) which are disposed around the plurality of side walls 1b, and a space is provided between two adjacent ring beams along the height direction of the side walls 1 b. Specifically, when the concrete foundation slab 1a is piled up with the masonry 111 up to a certain height, a ring beam is horizontally provided on the side wall 1b of the treatment tank. For example: assuming that the width of the masonry 111 is 300mm or less, a ring beam needs to be horizontally arranged on the side wall 1b of the treatment pool when the number of layers of the masonry 111 is not more than 15, specifically: when the number of layers of the stacked masonry 111 is 5, ring beams may be horizontally provided on the side walls 1b of the treatment tank. For another example: assuming that the width of the masonry 111 is 400mm or more, it is necessary to horizontally arrange a ring beam on the side wall 1b of the treatment tank when the number of layers of the masonry 111 is not more than 20, and to vibrate with a vibrating rod to ensure that the concrete of the ring beam is sufficiently dense. The method comprises the following steps: when the number of layers of the stacked masonry 111 is 7, ring beams may be horizontally provided on the side walls 1b of the treatment tank.
The adoption of the ring beam design is beneficial to preventing the occurrence of damage to the treatment pool caused by uneven settlement of the foundation, earthquake or other large vibration load.
In this embodiment, the treatment station further comprises a grating pond 10, the grating pond 10 and the treatment ponds are arranged on the underground layer of the hospital, and the treatment ponds comprise a first pond part and a second pond part, and the second pond part is arranged side by side and parallel to the first pond part. The grid pool 10 and the treatment pool are arranged on the underground layer of the hospital, so that the space on the upper layer of the ground is not occupied, the space can be vacated for other purposes, and the engineering land can be saved.
Specifically, as shown in fig. 3 and 4, the first tank portion and the second tank portion each include a regulating tank 11, an oxidation reaction tank 12, an adsorption tank, a sedimentation tank 14, a disinfection tank 15, and a discharge tank 16 which are sequentially arranged in a straight line, and the regulating tank 11, the oxidation reaction tank 12, the adsorption tank, the sedimentation tank 14, the disinfection tank 15, and the discharge tank 16 of the second tank portion are respectively arranged in one-to-one correspondence with the regulating tank 11, the oxidation reaction tank 12, the adsorption tank, the sedimentation tank 14, the disinfection tank 15, and the discharge tank 16 of the first tank portion, and the grille tank 10 is disposed at one side of the regulating tank 11 of the first tank portion and the regulating tank 11 of the second tank portion, that is, the first tank portion, the second tank portion, and the grille tank 10 are arranged in approximately '￢' shape. By adopting the layout mode, the overall layout structure of the treatment water tank is more compact and reasonable, the overall occupied area is reduced, the engineering land is saved, and the cost is saved.
Wherein, the discharge tank 16 of the first water tank part is communicated with the discharge tank 16 of the second water tank part, i.e. no side wall 1b is arranged between the discharge tank 16 of the first water tank part and the discharge tank 16 of the second water tank part, so that the construction of the treatment station can be reduced, and the cost can be further reduced.
Specifically, the grill cell 10 is disposed on one side of the first basin section, adjacent to the conditioning tank 11 of the first basin section, and the second basin section is disposed on the other side of the first basin section.
The adsorption tank comprises a coagulation tank 13a and a flocculation tank 13b, wherein the coagulation tank 13a and the flocculation tank 13b are arranged side by side and in parallel, and sewage generated by a hospital passes through the coagulation tank 13a and then passes through the flocculation tank 13b. Specifically, the main functions of the coagulation tank 13a are: by adding some chemicals (usually positively charged coagulant) to the coagulation tank 13a, the particles in the sewage are mutually combined and enlarged under the actions of mutual collision, surface adsorption, van der Waals attraction and the like, so that the separation from the sewage is facilitated. The main functions of the flocculation basin 13b are: by adding some medicaments (usually coagulant aids) into the coagulation tank 13a, particles in the sewage in the flocculation tank 13b, which are difficult to separate from the sewage in the coagulation tank 13a by precipitation, can be mutually polymerized to form colloid, and then are combined with impurities in the sewage to form larger floccules, so that the sewage can be precipitated from the sewage, and the effect of further purifying the sewage is achieved.
Further, a water pump (not shown) is provided in each of the treatment tanks, and in the two adjacent treatment tanks of the first tank portion and the second tank portion, the water pump is used for conveying the sewage in one of the two adjacent treatment tanks to the other of the two adjacent treatment tanks.
Further, in order to remove soft entanglement, large solid particle impurities and floating matters in the sewage generated in the hospital before the sewage enters the regulating tank 11, it is preferable that the grille tank 10 is disposed before the sewage generated in the hospital enters the regulating tank 11, and the grille tank 10 is respectively communicated with the regulating tank 11 of the first water tank part and the regulating tank 11 of the second water tank part, so that the effect of removing soft entanglement, large solid particle impurities and floating matters in the sewage before the sewage enters the regulating tank 11 is achieved, thereby being beneficial to protecting the service life of the subsequent water pump and reducing the work load of the treatment station for treating the sewage.
The hospital sewage treatment station in this patent is mainly used for treating hospital sewage, and the treatment process of the hospital sewage treatment station of the present invention is described briefly below:
The sewage generated by the hospital is subjected to solid-liquid separation sequentially through a grid tank 10, an adjusting tank 11, an oxidation reaction tank 12, a coagulation tank 13a, a flocculation tank 13b and a sedimentation tank 14, the separated sludge enters a sludge tank 18 for concentration and then enters a filter press for filtration, and the filtered dry sludge enters a solid waste center for treatment and unified treatment; the sewage separated by the sedimentation tank 14 is discharged into the disinfection tank 15, wherein chlorine dioxide decomposed by the chlorine dioxide generator is mainly utilized in the disinfection tank 15 to disinfect the sewage, and the sewage after the disinfection tank 15 disinfects the sewage which is the raw water meeting the standard can be directly discharged into a sewage pipe network of a city and then treated uniformly.
In this embodiment, the treatment station further comprises a control system (not shown) for controlling the first basin section to start operating when the wastewater of the treatment station is at the first water level, or for controlling the second basin section to start operating; and when the sewage of the treatment station is at a second water level, the control system is used for controlling the first water tank part and the second water tank part to start to operate, wherein the second water level is higher than the first water level.
It can be known that the first water level may be: the water level of the sewage entering the grille pool 10 is half of the height of the side wall of the grille pool 10 and below, namely the water level of the sewage when the sewage to be treated by the treatment station is relatively small; and the second water level may be: the sewage level of the sewage entering the grille pool 10 is half or more of the height of the side wall of the grille pool 10, namely the sewage level when the sewage to be treated by the treatment station is more.
The hospital sewage treatment station comprises two water tank parts, and each water tank part is provided with an independent control system, so that the treatment station can determine the number of the operating treatment water tanks according to the total amount of the actual sewage to be treated, namely, when the sewage of the treatment station is positioned at a first water level, namely, the hospital sewage treatment station is in a low load state, only one water tank part of the first water tank part or the second water tank part can be operated, and when the sewage of the treatment station is positioned at a second water level, namely, the treatment station is in a full load state, the first water tank part and the second water tank part can be operated simultaneously, thereby being beneficial to improving the efficiency of the treatment station for treating the sewage and saving energy efficiently.
In addition, the independent control systems adopted by the invention are all of integrated design, and can fully automatically control the full-automatic operation of equipment in the treatment station, thereby being beneficial to facilitating the use and management of the sewage treatment station and reducing the management difficulty.
It should be appreciated that the treatment process of the first tank section and the second tank section to treat the wastewater is non-interfering, such as: when the treatment water tank of the first water tank part fails and cannot operate, the second water tank part can still normally operate to treat sewage; similarly, when the treatment water tank of the second water tank part fails and cannot operate, the first water tank part can still normally operate to treat sewage.
In this embodiment, the treatment station further comprises a facility room 17 provided in an underground floor of the hospital and a sludge tank 18 provided at one side of the facility room 17, the facility room 17 being provided near the oxidation reaction tank 12 and the adsorption tank of the first tank portion. Specifically, the equipment room 17 communicates with the sedimentation tank 14 and the sludge tank 18 of the first water tank portion and the second water tank portion, respectively, for transporting the sludge in the sedimentation tank 14 to the sludge tank 18. The sludge tank and the sedimentation tank are not arranged side by side, so that the layout of the treatment station is more reasonable and compact, and the occupied area of the treatment station can be reduced. In addition, in order to avoid the problem that a large amount of sludge is generated due to excessive sewage treated by the hospital sewage treatment station, the sludge in the sedimentation tank is difficult to rapidly transport to the sludge tank 18 between the facilities, and the treatment station further comprises a reserved facility room 23 arranged at one side of the facility room 17.
It will be appreciated that since the concentration of dissolved oxygen in the treatment basin is generally relatively low, which can easily lead to the difficulty of reaching the standard of the discharged sewage, the treatment station also comprises a blower room 24 arranged between the sludge basin 18 and the holding room 23, generally in order to increase the concentration of dissolved oxygen in the treatment basin. The blower room 24 is mainly used for aerating a treatment pool, namely, compressed air is sent into the treatment pool through a pipeline so as to meet the oxygen amount required by aerobic microorganisms in the treatment pool and the mixing condition that sewage fully contacts with activated sludge, thereby further improving the purification efficiency of sewage treatment.
In addition, in order to be able to supply power to the equipment used in the hospital sewage treatment station (e.g. water pumps, sludge pumps, fans in the blower room, etc.), the treatment station also comprises a distribution room 25 provided on one side of the equipment room 17.
In this embodiment, in order to be able to store sewage in time in the event of a failure of any treatment basin and/or grille basin 10, and to avoid the untreated discharge of sewage, the treatment station further comprises an accident basin 19 which is provided in the underground floor of the hospital and can temporarily store sewage, the accident basin 19 being located between the equipment room 17 and the grille basin 10, and the accident basin 19 being in communication with the regulating basin 11. The accident pool 19 needs to be communicated with the adjusting pool 11, mainly because the accident pool 19 cannot play a role in purifying sewage, but plays a role in temporarily storing sewage when any treatment pool and/or grille pool 10 fails to treat sewage, that is, after maintenance of the treatment pool and/or grille pool 10 is completed, the sewage in the accident pool 19 still needs to be conveyed to the treatment pool for treatment. That is, if a portion of the treatment tanks in the first tank section fail, the sewage in the failed treatment tank is transferred to the accident tank for storage.
Similarly, if a part of the treatment water tanks in the second water tank part fail, the sewage in the failed treatment water tanks can be conveyed to the accident tank for storage.
Similarly, if the treatment pool of the first pool portion and the treatment pool of the second pool portion fail, the sewage in the failed treatment pool is transported to the accident pool for storage.
Similarly, when the grid pool 10 fails and needs to be overhauled, the treatment station can not treat sewage temporarily, the sewage generated by the hospital at the moment can enter the accident pool 19 and is temporarily stored in the accident pool 19, and after the grid pool 10 is maintained, the sewage in the accident pool 19 is conveyed to the treatment pool to treat the sewage.
In this embodiment, since the sludge separated from the sedimentation tank 13 is moist, i.e. the sludge in the sludge tank is also moist, the treatment station further comprises a sludge dewatering space 20 arranged on the floor level of the hospital for drying the sludge in the sludge tank, which sludge dewatering space 20 is located above the accident tank 19 for facilitating the sludge to enter the filter press for filtration.
Referring to fig. 5 and 6, for convenience in centralized treatment and management of medical waste, household waste and sewage, a medical waste room 22 and a household waste room 21 are arranged side by side on the ground of a hospital, and the medical waste room 22 and the household waste room 21 are arranged above the equipment room 17, wherein the medical waste room 22 is adjacent to the sludge dewatering room 20, so that filtered dry sludge, medical waste and household waste are conveniently transported to a solid waste center for treatment and unified treatment, that is, the centralized management of dangerous sewage in the hospital is facilitated, and the matched functional areas such as an outpatient service building of the hospital are simplified.
In addition, since each treatment tank requires chemical agents to be added when treating sewage, and in order to reduce the floor space of the treatment station for the hospital floor, a dosing room 26 and a medicine storage room 28 are provided at the hospital floor. The dosing chamber 26 is located at one side of the house 21 and is mainly used for delivering the required chemical agents to the treatment pool. Because the medicine compartment 28 is mainly used for storing various chemical agents used in the medicine compartment 26, the chemical agents in the medicine compartment 28 are conveniently transported to the medicine compartment 26, and the medicine compartment 28 is arranged adjacent to the medicine compartment 26 and above the blower room 24.
Also, in order to reduce the floor space of the treatment station for the underground layer of the hospital and to ensure that the sewage discharged from the hospital sewage treatment station meets the sewage discharge standard, a laboratory 27 is further provided on the ground upper layer of the hospital and is arranged side by side with the medicine storage room 28, the laboratory 27 is arranged above the blower room 24, and the laboratory 27 is mainly used for detecting whether the sewage passing through the disinfection tank 15 meets the discharge standard or not, so that the condition that the environment is polluted due to the condition that the substandard sewage is discharged through the discharge tank 16 can be avoided, thereby being beneficial to ensuring that the sewage discharged through the discharge tank 17 meets the sewage discharge standard and avoiding the environment pollution.
In this embodiment, since the treatment tank is disposed in an underground floor of a hospital, in order to further enhance the carrying capacity of the treatment tank, a concrete ceiling 1c is disposed above the treatment tank, and the ceiling concrete ceiling 1c is used to close the opening of the treatment tank corresponding thereto. Specifically, the concrete top plate 1c is a prefabricated member, that is, the concrete top plate 1c is customized in a factory in advance and then transported to a site for installation, so that the construction period of the treatment station can be reduced, the efficiency of the treatment station can be improved, and the construction cost can be further saved.
In addition, each treatment pool corresponds to one concrete roof 1c, and gaps between two adjacent concrete roof 1c are filled with cement mortar. Each treatment pool corresponds to one concrete roof 1c, so that the concrete roof is convenient to transport.
Further, in order to prevent the sewage in the treatment tanks from leaking out, the surface of each concrete ceiling 1c and the plurality of side walls 1b of each treatment tank are each provided with a waterproof mortar layer (not shown). Also, in order to prevent the sewage from corroding the concrete ceiling 1c and the side walls 1b of the treatment tank, the surface of the waterproof mortar layer is coated with an anticorrosive paint.

It should be noted that: in the places where the space for stacking is insufficient and the size of the half masonry 111 is insufficient, pouring of concrete into the holes is required. In addition, when the masonry 111 is to be stacked, it is necessary to ensure full mortar, uniform mortar, and follow-up of the mortar.
The embodiment of the invention provides a modular hospital sewage treatment station, which adopts a plurality of brickworks with hollow parts to pile and splice to form the side wall of a treatment water tank, and the structural strength of the brickworks can be enhanced by placing reinforcing steel bars and core concrete in the hollow parts, so that the strength and the rigidity of the side wall of the treatment water tank can be enhanced, the volume of the treatment water tank can be increased by increasing the height of the side wall, the occupied area of the treatment station can be reduced, the space utilization rate of the treatment station can be improved, and the comprehensive use benefit of the land of the treatment station can be improved. Moreover, the brickwork adopts the modularized design, and each module brickwork can be prefabricated in advance, and then is transported to the scene for rapid assembly, thereby greatly reducing the design construction period, reducing the construction difficulty and saving the construction cost.
