Background technique

Sponge city is a new generation of urban stormwater management concept. It means that the city can be like a sponge and have good "elasticity" in adapting to environmental changes and responding to natural disasters. When it rains, it absorbs, stores, seeps and purifies water. It needs The stored water is then "released" and used. Through urban planning, construction, and management, sponge cities realize the control and utilization of rainwater on different underlying surfaces such as buildings and communities, urban roads, green spaces and squares, and urban water systems, so as to restore water ecology, improve water environment, ensure water safety, and conserve water. Multiple goals for resources.

Sponge cities store and utilize rainwater when it rains. When rainwater flows on the road surface, the rainwater will be mixed with dust, leaves and other impurities. Eventually, sewage will flow into the city's underground pipes, which can easily pollute groundwater. And cause pipeline blockage, so a floating sponge city rainwater and sewage treatment device and treatment method are proposed.

The invention also provides a method for treatment using the above-mentioned floating sponge city rainwater treatment device. The method includes the following steps:

Step 1: Install the sewage treatment device as a whole in the ground channel, and set protective measures such as manhole covers on the top of the shell. When rainwater enters the inside of the shell, the rainwater will be filtered by the filter plate for the first time, and then the rainwater will fall to the filter Secondary filtration and purification is performed in the barrel;

Step 2: When rainwater gradually accumulates inside the filter barrel, the filter barrel lifts the filter plate through the rope, which allows the support frame to rise. At this time, the indicator light is above the ground and lights up;

Step 3: When excessive rainfall begins to pour into the housing, the filter plate begins to move downward due to the impact of the rain. At the same time, the bottom of the filter plate will contact the T-shaped plate and the T-shaped plate will move downward together. Then the rainwater will Enter into the tee head through the chute, and then drain the accumulated water in the shell through the drain pipe;

Step 4: While the filter plate moves downward, the bump will contact the spiral groove of the drill bit, and the drill bit will be squeezed downward through the bump, causing the drill bit to start rotating with the bearing;

Step 5: When the water pipe discharges a large amount of rainwater into the storage bucket, the heavier objects such as mud will settle at the bottom of the storage bucket, while the lighter objects such as leaves will be intercepted by the filter bucket, and the rainwater can be discharged from the storage bucket. The storage bucket overflows to the outside;

Step 6: When the water accumulation in the housing decreases, the filter plate begins to rise. At the same time, the spring will press upward against the T-shaped plate to stop the drain pipe from draining. Then, connect the top of the drain pipe to an external device to remove the impurities in the bucket. aspirate;

Step 7: When it is difficult to absorb the impurities inside the storage barrel, lift the entire device and release the limit plate to limit the storage barrel, then take out the filter bucket and clean it. When the entire equipment is cleaned, you can Rotate the bucket to reset and place the device back into the channel again.

The beneficial effects of the present invention are: when the rainwater enters the inside of the shell, the polluted rainwater will be filtered by the filter plate for the first time. After the rainwater is filtered by the filter plate, it will fall into the filter barrel through the filter holes of the filter plate and be filtered by the filter plate. After secondary filtration, the clean rainwater can be discharged from the chute at the bottom of the housing. Impurities in the water can be double filtered through the filter plate and filter barrel to reduce pollution.

When a large amount of rainwater accumulates inside the filter barrel, the filter barrel pulls the filter plate upward by its own gravity through the rope. At this time, the support frame will also move upward with the filter plate, and then the indicator light will light up to alert the outside world. When the rainfall is too heavy, the float floats up through the accumulated water and drives the round rod to move upward, so that the indicator light can continue to work without being affected by the accumulated water.

When the rainfall is large, the filter plate cannot filter it quickly. At this time, a large amount of rainwater will press the filter plate downward. When the filter plate moves downward, the bottom of the filter plate will press against T The profile plate causes it to move downward synchronously, thereby opening the water outlet of the chute and allowing a large amount of rainwater to be discharged from the drainage pipe. The equipment can then automatically float up and down to adjust the amount of drainage according to the amount of rainfall, and the water can be discharged in a timely manner. Drain the accumulated water.

When the filter plate moves downward, the bumps will come into contact with the spiral groove of the drill rod, and the drill rod will be squeezed downward along the spiral groove by the bumps, and the drill rod will rotate in the filter hole of the filter plate, so that Dust and other impurities are squeezed onto the surface of the filter plate and are discharged from the drain pipe along with the rainwater. When the filter plate is reset, the cleaning is completed and the rainwater can be continued to be filtered.

When the drainage pipe discharges rainwater into the storage bucket, heavier objects such as mud mixed in the rainwater will settle at the bottom of the storage bucket, and lighter objects such as leaves will be blocked by the filter bucket, allowing them to float on the storage bucket. Then the rainwater can overflow out of the storage bucket through the filter bucket. Finally, by connecting the drainage pipe to an external device, the impurities in the storage bucket can be sucked out, allowing it to continue filtering the rainwater.
