Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1, the controllable slow flow sewage interception circulation module system based on sponge city construction disclosed by the invention comprises an artificial wetland 1, a water storage tank 2 and a water storage tank 3 which are respectively connected with the artificial wetland 1. The artificial wetland 1 comprises a planting layer 11 and a filter layer 12 from top to bottom, wherein soil is arranged in the planting layer 11, green plants are planted on the soil, and the filter layer 12 is charcoal with an outer layer coated with geotextile. A first water pipe 21 for communicating the artificial wetland 1 and the water storage tank 2 is arranged between the artificial wetland 1 and the water storage tank 3, a second water pipe 31 for connecting the artificial wetland 1 and the water storage tank 3 is arranged between the artificial wetland 1 and the water storage tank 3, the position of the first water pipe 21 connected with the artificial wetland 1 is higher than the position of the second water pipe 31 connected with the artificial wetland 1, and the positions of the first water pipe 21 and the second water pipe 31 connected with the artificial wetland 1 are both positioned on the filter layer 12. The positions of the first water pipe 21 and the second water pipe 31 connected with the artificial wetland 1 are respectively higher than the upper ends of the water storage tank 2 and the water storage tank 3, and the water storage tank 3 is connected with a first drainage pipe 32 which drains water towards a river channel. When raining, the rainwater is earlier through constructed wetland 1 entering reservoir 2 in, in the rainwater gets into cistern 3 after continuing to be full in reservoir 2, in the river course of discharging into after that, initial stage rainwater major part is located reservoir 2 and can not directly discharge into the river course this moment to make river course quality of water can not worsen fast.
As shown in fig. 1, since the water in the water storage tank 2 is continuously filled and the water in the water storage tank 2 needs to be drained after the rain stops, the water storage tank 2 is connected with a second drainage pipe 22 for draining water towards the water storage tank 3, one end of the second drainage pipe 22 is connected to the lower end of the water storage tank 2, the other end of the second drainage pipe 22 is connected to the upper end of the side wall of the water storage tank 3, the end of the second drainage pipe 22 connected with the water storage tank 3 is higher than the end thereof connected with the water storage tank 3, and the second drainage pipe 22 is connected with a second valve 26 for controlling the on-off state thereof. At the moment, after the rain stops, the water in the water storage tank 2 is discharged into the water storage tank 3 for treatment and then is discharged into the river channel, so that the pollution of initial rainwater to the river channel is further reduced.
As shown in fig. 1, since the second valve 26 is opened, the rainwater may flow into the reservoir 3 and then into the river channel immediately after entering the storage tank 2. Therefore, the second drainage pipe 22 is spirally bent, and the bent second drainage pipe 22 slows down the flow rate of the water flowing through the second drainage pipe 22, so that the water in the water storage tank 2 does not completely flow into the water storage tank 3 at once, and the pollution of initial rainwater to the river channel is reduced.
As shown in fig. 1, since the initial rainwater contains more pollutants, and at this time, the initial rainwater needs to be primarily treated after entering the water storage tank 2, a buoyant raft 23 is arranged in the water storage tank 2, and aquatic plants for purifying water, such as hydrilla verticillata and reed, are planted in the buoyant raft 23. At this time, the initial rainwater is purified by the aquatic plants planted on the floating raft 23, and the floating raft 23 can move up and down along with the movement of the water level, so that the aquatic plants cannot die due to the dehydration.
As shown in fig. 2, since most of the water in the reservoir 2 is discharged after the water in the reservoir 2 is discharged into the water storage tank 3 through the second water discharge pipe 22, it is troublesome to manually control the water content in the reservoir 2. Therefore, the bottom surface of the water storage tank 2 is provided with a plurality of water storage tanks 24, and when the lower end of the floating raft 23 is abutted against the bottom surface of the water storage tank 2, the root system of the aquatic plant planted in the floating raft 23 is arranged in the water storage tank 24. After the second drain pipe 22 discharges the water in the reservoir 2, the growth of the aquatic plants is not affected by using a part of the water remaining in the reservoir 2 in the reservoir 24.
As shown in fig. 2, since the water storage tank 2 is used for a long time, more impurities are deposited in the water storage tank 24, thereby affecting the amount of water stored in the water storage tank 24. Therefore, the water storage tank 24 is inserted with a cleaning box 25 with an upper opening structure, and the outer wall of the cleaning box 25 is abutted with the inner wall of the water storage tank 24. After having impurity to deposit in the play tank 2, will clear up box 25 and take out from the aqua storage tank 24 and clear up to it is more convenient to make the clearance of the impurity of deposit in the aqua storage tank 24.
As shown in fig. 1, because the artificial wetland 1 needs to be watered, the reservoir 3 is connected with a water return pipe 33 for returning water to the artificial wetland 1, the water return pipe 33 is connected with a water pump 34 for driving water to move towards the artificial wetland 1, the water pump 34 is connected with a storage battery, one end of the water return pipe 33 connected with the reservoir 3 is close to the bottom surface of the reservoir 3, one end of the first water discharge pipe 32 connected with the reservoir 3 is higher than the bottom surface of the reservoir 3, and the opening of the water return pipe 33 close to the artificial wetland 1 is positioned above the artificial wetland 1. When the artificial wetland 1 needs to be irrigated, the water in the water storage tank is discharged towards the artificial wetland 1 by the water return pipe 33, and at the moment, water is not required to be conveyed from other places for irrigation.
As shown in fig. 1, when the water in the reservoir 3 is discharged into the river, it is necessary to sterilize the water in the reservoir 3. Therefore, the water reservoir 3 is connected with a medicine adding barrel 35 for disinfecting water, a dropper 36 for limiting the downward flowing speed of the water in the medicine adding barrel 35 is welded at the lower end of the medicine adding barrel 35, and the upper end of the dropper 36 is communicated with the inner cavity of the medicine adding barrel 35. Utilize and add medicine bucket 35 and drip the sterile water into cistern 3 in, carry out disinfection treatment to the water in the cistern 3, make the water of discharging in the cistern 3 in the river course can not produce the pollution to the river course.
The implementation principle of the embodiment is as follows: in the rainwater of surface runoff flows into constructed wetland 1 during rainy, later flow into in the aqua storage tank 24 through filter layer 12, rivers in constructed wetland 1 after water in the aqua storage tank 24 is full flow into cistern 3, the water that flows into in the cistern 3 is discharged into in the river course after the liquid medicine disinfection of adding medicine bucket 35 conflict, open second drain pipe 22 after the rain stops, pass through 3 rows into in the river course with the rainwater in the tank 2, the aquatic plant that plants on the water in the tank 2 can pass through buoyant raft 23 simultaneously purifies.
The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
