Technical Field
The invention relates to the technical field of sewage treatment, in particular to a river sewage treatment system with purification and water storage functions.
Background
The sponge city is like a sponge, has the effects of absorbing water, storing water and permeating water when raining, releases and utilizes the stored water when needed, and realizes the free migration of rainwater in the city. Therefore, the existing sewage treatment system is urgently required to be optimized, so that the system has multiple effects of water absorption, water storage, water seepage and water purification.
On the other hand, because rainwater or river sewage contains a large amount of suspended solids and solid particles, people can first pass rainwater into the sedimentation tank before passing the river sewage or the rainwater into the sewage treatment system. However, if the sedimentation tank is used for a long time, sediment is accumulated at the bottom of the sedimentation tank, if the sediment is not cleaned for a long time, the accumulated sediment occupies the tank body space, and the effective sedimentation area is reduced, so that the efficiency of sediment suspended matters and solid particles is reduced, the suspended matters and the particles cannot be effectively removed, and the performance of the whole sewage treatment system is affected.
To improve the performance of sewage treatment systems, one typically cleans the sediment in the sedimentation tank periodically. At present, people clear up the sedimentation tank and mostly adopt the mode of manual cleaning, and the workman gets into in the sedimentation tank and washs the precipitate, and the workman gets into the cost of clearing up in the sedimentation tank higher, and because there are more harmful substance in the mud, the danger is also great. Accordingly, there is still room for improvement.

The implementation principle of the embodiment is as follows:
when rainfall occurs in a city or river sewage needs to be treated, introducing rainwater or river sewage into the grid pond 1 from the grid pond water inlet pipe 11, filtering for a period of time, introducing the rainwater or river sewage into the sedimentation pond 2 from the grid pond water outlet pipe 12, enabling suspended matters and solid particles in the rainwater or river sewage to be deposited at the bottom of the sedimentation pond 2, then introducing the rainwater or river sewage into the water collecting well 3 from the sedimentation pond water outlet pipe 24, starting the water pump 31 after the water collecting well 3 reaches a certain water level, introducing the rainwater or river sewage into the infiltration unit 4 for deep filtration, and finally introducing the treated rainwater or river sewage into the water collecting module 5 and the river; if the weather is in a heavy rain state, the water collecting module water outlet pipe 51 and the electric valve water outlet pipe 52 are closed, water is not discharged to the river, and the water collecting module 5 continuously stores water, so that urban flood control is facilitated.
When the sediment in the sedimentation tank 2 needs to be cleaned, the driving rod 71 is moved, so that the driving rod 71 moves in a direction away from the bottom of the driving groove, the driving rod 71 drives the rotating sleeve 61 to drive the protruding rod 62 to move in a direction away from the collecting cloth 21, so that the protruding rod 62 is arranged in the groove, then the worker pulls out the adjacent fixing rods 22, so that the aggregation piece 8 restores elasticity, the aggregation piece 8 drives the adjacent fixing rods 22 to move in a direction of the non-pulled fixing rods 22, so that the fixing rods 22 are aggregated, then the worker pulls out the other two fixing rods 22, four fixing rods 22 aggregate, the collecting cloth 21 wraps the sediment, then the fixing rods 22 are driven to move in a direction away from the sedimentation tank 2, so that the sediment is separated from the sedimentation tank 2, the cleaning of the sedimentation tank 2 is completed, the step that the worker enters the sedimentation tank 2 is reduced, the cost of the worker is reduced, and the cost of cleaning the sedimentation tank 2 is further reduced; meanwhile, as the sludge contains more harmful substances, the steps that workers enter the sedimentation tank 2 to clean sediment are reduced, and the method is beneficial to protecting the workers.
Through setting up dead lever 22, sliding tray and spread groove 23, insert dead lever 22 in the dead slot, just can make collection cloth 21 parcel sedimentation tank 2 bottom and be close to the lateral wall of bottom, the lateral wall butt of collection cloth 21 and the lateral wall butt of sedimentation tank 2 are favorable to installing and dismantling collection cloth 21 portably, reduce the degree of difficulty of clearance sedimentation tank 2.
Through setting up of driving piece 7 and tightening up piece 6, remove actuating lever 71, just can make protruding pole 62 tighten up collection cloth 21, be favorable to reducing and continuously tighten up collection cloth 21, lead to collection cloth 21 elastic fatigue to lead to collection cloth 21 can move along with the flow of rivers, the precipitate disperses in sewage once more, and then lead to influencing sedimentation tank 2's filterable condition, be favorable to making things convenient for the workman to clear up sedimentation tank 2, do not influence sedimentation tank 2 sediment suspended solid and solid particle's efficiency again.
Through the arrangement of the rubber belts, the two adjacent fixing rods 22 are pulled out by workers, the elastic property of the rubber belts is recovered to gather the fixing rods 22 together, and then the gathered fixing rods 22 are moved towards the direction away from the bottom of the sedimentation tank 2 at the same time, so that the sedimentation tank 2 can be cleaned, only one worker or two workers can clean the sedimentation tank 2, the situation that four workers lift up the four fixing rods 22 at the same time to separate the collecting cloth 21 from the sedimentation tank 2 is facilitated, the sedimentation tank 2 can be cleaned better, and the cost for cleaning the sedimentation tank 2 can be reduced; meanwhile, the number of workers required for cleaning the sedimentation tank is reduced, and the speed of cleaning the sedimentation tank by workers is increased.
The embodiments of the present invention are all preferred embodiments of the present invention, and are not intended to limit the scope of the present invention in this way, therefore: all equivalent changes in structure, shape and principle of the invention should be covered in the scope of protection of the invention.
