Example 1
Referring to fig. 1-2, the present embodiment provides a composite flushing type stable storage tank, which mainly includes: a containing body 11 and a partition 12.
The accommodating main body 11 has an accommodating space therein, and a plurality of partitions 12 partition the accommodating space into a diversion gallery 112, a first sub-chamber 113 and a plurality of second sub-chambers 114 to partition the effective volume of the composite flushing type stable storage pool into a plurality of areas for accommodating rain and sewage mixed water. It should be noted that the first sub-plenum 113 and the second sub-plenum 114 may be located on the same side of the diversion gallery 112, or may be located on different sides of the diversion gallery 112 (i.e., the first sub-plenum 113 is located on one side of the diversion gallery 112, and the second sub-plenum 114 is located on the other side of the diversion gallery 112). When the first sub-compartment 113 and the second sub-compartment 114 are located on opposite sides of the diversion gallery 112, the first sub-compartment 113 and the second sub-compartment 114 may be connected by a pipe so that the rain and sewage mixed water in the first sub-compartment 113 enters the second sub-compartment 114. In this embodiment, the first sub-chamber 113 and the second sub-chamber 114 are preferably disposed on the same side of the diversion gallery 112 to simplify the structure of the composite flushing type stable storage pool, so that the structure of the composite flushing type stable storage pool is more regular, and the operation and maintenance of the composite flushing type stable storage pool are facilitated.
In this embodiment, the first sub-chamber 113 is opened with a first water inlet 115 capable of communicating with the diversion gallery 112, and a first overflow weir gate 116 is disposed at the first water inlet 115. The second sub-chamber 114 is provided with a second water inlet 117 capable of being communicated with the first sub-chamber 113, and a second overflow weir gate 118 is arranged at the second water inlet 117. When the rainfall is large, the rain-sewage mixed water can enter the second sub-compartment 114 through the second water inlet 117 after entering the first sub-compartment 113. The diversion gallery 112 has an inlet 111, and a first sub-plenum 113 is located between the inlet 111 and a second sub-plenum 114.
After entering the diversion gallery 112 from the water inlet 111, the rain and sewage mixed water can enter the first sub-chamber 113 from the first water inlet 115 and then enter the second sub-chamber 114 from the first sub-chamber 113. The stable pond of compound flushing type can realize the subregion control to the concentration of pollutant in the dirty mixed water of rain, promptly: when the rainfall is large, and the rain and sewage mixed water with high pollutant content enters the first sub-chamber 113, the first sub-chamber 113 can play a role in pre-settling and purifying the rain and sewage mixed water, so that pollutants are concentrated in the first sub-chamber 113, and the pollutants are conveniently and intensively cleaned; due to the deposition of the pollutants in the first sub-compartment 113, the pollutant content of the rain and sewage mixed water entering the second sub-compartment 114 is low, and the operation and maintenance of the second sub-compartment 114 are facilitated. In addition, because the stable pond of compound flushing type can realize the subregion control to the concentration of pollutant in the rain sewage mixed water for quality of water in each minute bin is comparatively stable, and this is favorable to handling the rain sewage mixed water in each minute bin respectively through outside water treatment facilities (when quality of water is unstable, water treatment facilities is relatively poor to the treatment effect of rain sewage mixed water).
It should be noted that the number of the second sub-chambers 114 is not limited in the present embodiment, and there may be 1, 2 or 3 second sub-chambers 114, for example. When a plurality of second sub-chambers 114 are provided, the plurality of second sub-chambers 114 are sequentially communicated with each other, and a second overflow weir 118 is provided between any two adjacent second sub-chambers 114.
When the rainfall is small, an operator can start each second sub-chamber 114 one by one according to actual needs to fully utilize each second sub-chamber 114, and as the whole area of the composite flushing type stable storage tank does not need to be opened, no rain and sewage mixed water enters the part of the area which is not started, and the part of the area does not need to be maintained, thus providing greater flexibility and possibility for the operation and maintenance of the composite flushing type stable storage tank, and effectively reducing the workload and the cost of the operation and maintenance.
When the composite flushing type stable storage pool is designed, firstly, volume calculation and position selection are carried out through a computer model, then, historical rainfall data (such as rainfall intensity, rainfall duration, rainfall interval time, recurrence period and other parameters) of an area served by the composite flushing type stable storage pool are subjected to statistical analysis, then, a mathematical model is established according to an analysis result, rainfall conditions are predicted through the mathematical model, finally, various rainfall conditions are classified, and probability of occurrence of various rainfall conditions is analyzed (such as conventional rainfall probability of 80% and strong rainfall probability of 20%), on the basis, the composite flushing type stable storage pool is reasonably divided into a plurality of areas, namely, the composite flushing type stable storage pool is divided into a first cabin 113 and a plurality of second cabins 114.
One side of the diversion gallery 112 can be provided with a diversion pipe 119, and a diversion gate 121 is arranged at the diversion pipe 119. When the rainfall occurs, the amount of the rain and sewage mixed water of the upstream pipe network is increased, in order to ensure the stable operation of the downstream pipe network and a sewage plant, the excessive rain and sewage mixed water needs to enter the composite flushing type stable storage tank for temporary storage, and at the moment, the overflow liquid level of the rain and sewage mixed water entering the first branch chamber 113 can be adjusted through the first overflow weir gate 116, so that the rain and sewage mixed water is ensured to preferentially enter the first branch chamber 113 through the first water inlet 115; after the rainfall, when low reaches pipe network and sewage plant resume the operating capacity, can discharge the mixed water of rain and sewage in the stable pond of compound flushing type to the sewage plant by shunt tubes 119 and handle, at this moment, the first overflow weir door 116 of accessible is adjusted the overflow liquid level that the mixed water of rain and sewage got into first minute bin 113 to guarantee that the mixed water of rain and sewage preferentially gets into the sewage plant through shunt tubes 119.
The diversion gallery 112 has an outlet portion 122, and the outlet portion 122 can be connected to a downstream piping network. A drainage weir 123 is arranged in the diversion gallery 112, and the drainage weir 123 is arranged close to the water outlet part 122. The drainage weir gate 123 can be, for example, a hydraulic lifting weir gate, and the drainage weir gate 123 can be opened to discharge the rain and sewage mixed water into a downstream pipe network. Of course, the rain and sewage mixed water in the composite flushing type stable storage tank does not need to be discharged to a downstream pipe network or a sewage plant, and a user can be externally connected with water treatment equipment to treat the rain and sewage mixed water in the composite flushing type stable storage tank and then utilize the treated rain and sewage mixed water.
The first weir gate 116 and the second weir gate 118 can be hydraulically driven to improve the safety and reliability of the first weir gate 116 and the second weir gate 118.
The water inlet part 111 can be provided with a grating 124 to intercept floating objects in the rain and sewage mixed water, so that the floating objects are prevented from entering the composite flushing type stable storage pool, and the difficulty of cleaning the composite flushing type stable storage pool is increased. The grid 124 may be a thick grid 124 or a thin grid 124. The user can select the specification of the grating 124 according to the actual requirement.
The existing flushing technologies are various, and each flushing mode has advantages, disadvantages and application range, for example, although the tipping bucket type flushing is simple to control, the flushing range is limited and an external water source needs to be supplemented; the door type flushing effect is good, but only one-time flushing is needed, so that the stable storage tank is not easy to be thoroughly flushed; although the vacuum washing has larger washing area, the vacuum washing has high requirement on civil construction; the jet type washing is thorough, but the running cost is high. At present, only one washing mode is usually adopted, and various washing modes have the advantages and the disadvantages, so that the problems of poor washing effect or higher operation cost are easily caused.
In order to alleviate above-mentioned problem, stable pond of compound flushing type can also be including washing the mechanism, wash the mechanism and mainly can wash subassembly 13 and gate-type including the jet type and wash subassembly 14, the jet type washes subassembly 13 and sets up in first minute bin 113, the gate-type washes subassembly 14 and sets up in second minute bin 114, with the characteristics according to first minute bin 113 and second minute bin 114, choose the different modes of washing for use, avoid the weak point in the advantage of making good for, when guaranteeing to wash the effect, compromise the cost and the convenience that the operation of stable pond of compound flushing type was maintained.
Because the utilization rate of the first sub-chamber 113 is high, the content of the stored pollutants is high, and more deposits are generated, the jet type flushing assembly 13 with a better flushing effect is arranged in the first sub-chamber 113; because the utilization ratio of the second sub-chamber 114 is lower, the content of the stored pollutants is lower, and the generated deposition is less, the door type flushing assembly 14 is arranged in the second sub-chamber 114, so that the flushing effect is ensured, and the cost and the convenience of the operation and the maintenance of the composite flushing type stable storage pool are taken into consideration.
In this embodiment, the jet-type washing assembly 13 may mainly include a first base 131, a water pump 132, and a water spraying head 133, wherein the water spraying head 133 is connected to the water pump 132, and the water pump 132 is installed on the first base 131. The water pump 132 can flush the bottom of the first sub-compartment 113 with water within the first sub-compartment 113.
The first base 131 may be fixedly installed in the first sub-compartment 113, or may be movably installed in the first sub-compartment 113. When the first base 131 is movably installed in the first sub-compartment 113, it helps to expand the flushing range of the jet-type flushing assembly 13 to better flush the first sub-compartment 113. There are various ways in which the first base 131 is movably installed in the first sub-compartment 113, for example, a moving wheel can be installed on the base 131, and this embodiment is not illustrated.
The gate type flushing assembly 14 mainly includes a stopper 141 disposed in the second sub-chamber 114, the stopper 141 is disposed near the diversion gallery 112, a first water storage chamber 142 is formed between the stopper 141 and the diversion gallery 112, the sub-chamber flushing gate 143 is mounted on the stopper 141, the first water storage chamber 142 is provided with a third water inlet 144 capable of communicating with the diversion gallery 112, and a third overflow weir gate 145 is disposed at the third water inlet 144.
When the area of the second sub-chamber 114 is large and the size of the sub-chamber flushing gate 143 is small, the second sub-chamber 114 is not easily cleaned completely after the sub-chamber flushing gate 143 is opened, and therefore, the partition member 146 may be disposed in the first water storage chamber 142, the partition member 146 may partition the first water storage chamber 142 into a plurality of water storage regions 147, and the sub-chamber flushing gate 143 is disposed at each water storage region 147. The second partial chamber 114 can be flushed better by opening all the partial chamber flushing gates 143 simultaneously.
When one of the sub-chamber flushing gates 143 is opened, the water in the corresponding water storage area 147 may flush the sediment to the vicinity of the other sub-chamber flushing gate 143 or between two adjacent sub-chamber flushing gates 143, so that the sediment is accumulated between the two adjacent sub-chamber flushing gates 143. In order to better flush the second sub-chamber 114, the bottom of the second sub-chamber 114 may be provided with protruding ridges 148, and the protruding ridges 148 correspond to the partitions 146 one to one. The convex edge 148 and the partition 146 are substantially in the same straight line, and after one sub-chamber flushing gate 143 is opened, the convex edge 148 can block and guide the sediment and water, so that the sediment is not easy to accumulate between two adjacent sub-chamber flushing gates 143, and the second sub-chamber 114 can be better flushed.
It should be noted that, in this embodiment, the size and the cross-sectional shape of the convex edge 148 are not limited, the size of the convex edge 148 can be reasonably selected according to actual needs, and the cross section of the convex edge 148 can be, for example, a triangle, so as to prevent the sediment from remaining on the top of the convex edge 148.
The bottom of the first sub-compartment 113 and/or the second sub-compartment 114 is provided with a water collection groove 149, and the water collection groove 149 is arranged far away from the diversion gallery 112. Since the pollutants in the rain and sewage mixed water naturally settle at the bottom of the pool to form accumulated silt after the rain and sewage mixed water enters the first sub-compartment 113, the second overflow weir gate 118 may be disposed near the water collecting tank 149 so as to introduce the rain and sewage mixed water with a lower pollutant content into the second sub-compartment 114.
The water collection tank 149 communicates with the second water storage chamber 151, and a water collection tank flushing shutter 152 is installed at one side of the second water storage chamber 151. By opening the sump flush gate 152, the sump 149 is flushed with water from the second reservoir 151 to adequately clean the composite flush ballast.
The second water storage chamber 151 is communicated with the first sub-compartment 113, and the second water storage chamber 151 may be communicated with the first sub-compartment 113 through a conduit 153, so as to flush the water collection tank 149 with the rain and sewage mixed water in the first sub-compartment 113.
After the composite flushing type stable storage tank is flushed by the flushing mechanism and the second water storage chamber 151, the sediment is accumulated near the water collecting groove 149 of the second water storage chamber 151, so that an operator can conveniently and intensively clean the sediment.
In order to further facilitate the cleaning of the sediment, a submersible sewage pump 154 is arranged in the water collection tank 149, and the submersible sewage pump 154 is communicated with a sewage discharge pipe 155. The submersible sewage pump 154 can pump the sediment located near the water collection tank 149 in the second water storage chamber 151 to a designated place.
The bottom of the water collecting tank 149 is provided with a pump pit 156, and the submersible sewage pump 154 is arranged in the pump pit 156. By providing the pump pit 156, the submersible sewage pump 154 can be placed as low as possible to thoroughly discharge the sediment.
The blow-off pipe 155 is communicated with the diversion gallery 112 to convey the precipitate into the diversion gallery 112, so that the precipitate can be conveniently discharged to a sewage plant or a downstream pipe network for treatment.
In this embodiment, the outlet of the sewage discharging pipe 155 is located between the first water inlet 115 and the second water inlet 117, and the sediment transferred into the diversion gallery 112 by the submersible sewage pump 154 can flow into the sewage plant through the diversion pipe 119 in a state that the sewage discharging weir gate 123 is closed and the diversion gate 121 is opened, so as to be conveniently treated.
In conjunction with the above structure, the working process of the composite flushing type stabilization tank will be described in detail below.
When the rain and sewage mixed water in the upstream pipe network is increased when the rain and sewage mixed water meets rainfall, in order to ensure that the operation of the downstream pipe network and a sewage plant is stable, the excessive rain and sewage mixed water needs to enter the composite flushing type stable storage tank for temporary storage. After the rain and sewage mixed water enters the diversion gallery 112 from the water inlet 111, the rain and sewage mixed water can preferentially enter the first water storage chamber 142 by adjusting the first overflow weir gate 116 and the third overflow weir gate 145, so that the second sub-chamber 114 can be conveniently flushed in the subsequent process. When the first water storage chamber 142 is full of water, the rain and sewage mixed water can enter the first sub-chamber 113 from the first water inlet 115, and then enter the second sub-chamber 114 from the first sub-chamber 113.
When the rainfall is great, behind the dirty mixed water of the higher rain of pollutant content got into first minute bin 113, first minute bin 113 can play the effect of precipitating purification in advance to dirty mixed water of rain, makes the pollutant concentrate in first minute bin 113, and the pollutant is concentrated in first minute bin 113, is convenient for concentrate the clearance pollutant. Due to the deposition of the pollutants in the first sub-compartment 113, the pollutant content of the rain and sewage mixed water entering the second sub-compartment 114 is low, and the operation and maintenance of the second sub-compartment 114 are facilitated.
When the rainfall is small, whether the second sub-chambers 114 are started or not can be reasonably selected by an operator according to actual needs to start each second sub-chamber 114 one by one so as to fully utilize each sub-chamber, and as all the second sub-chambers 114 do not need to be opened, part of the second sub-chambers 114 which are not started do not have the rain and sewage mixed water entering, and the part of the second sub-chambers 114 do not need to be maintained, so that greater flexibility and possibility are provided for the operation and maintenance of the composite flushing type stable storage pool, and the workload and the cost of the operation and maintenance are reduced.
After rainfall is finished, when the downstream pipe network and the sewage plant recover the operation capacity, the rain and sewage mixed water in the composite flushing type stable storage tank can be discharged to the sewage plant through the flow dividing pipe 119 for treatment. The overflow level may be regulated by a first overflow weir gate 116 to ensure that the stormwater mix preferentially enters the sewage plant through a shunt tube 119. The blowdown weir gate 123 can also be opened to discharge the rain sewage mixed water to a downstream pipe network.
When the composite flushing type stable storage pool needs to be cleaned, the first sub-chamber 113 can be flushed through the water spraying head 133, the second sub-chamber 114 can be flushed by opening the sub-chamber flushing gate 143, and the water collecting groove 149 can be flushed by opening the water collecting groove flushing gate 152, so that the purpose of fully cleaning the composite flushing type stable storage pool is achieved.
After the composite flushing type stable storage tank is flushed, the sediment is collected near the submersible sewage pump 154 and is conveyed to the diversion gallery 112 by the submersible sewage pump 154, and then the sediment is discharged to a sewage plant or a downstream pipe network for treatment when the downstream pipe network and the sewage plant recover the operation capacity.
