Description

Rural rainwater purification pond

technical field

The utility model relates to the technical field of water body purification, in particular to a rural rainwater purification pool.

Background technique

With the quickening pace of the times and the accelerating urbanization process, the supply and demand of water resources are also increasing, the problem of water resource shortage is becoming more and more obvious, and the pressure on the water environment is also gradually increasing. This undoubtedly changed the characteristics of the original natural ecological ontology and hydrological cycle, and destroyed the natural "sponge body". The countryside is rich in natural water bodies, but the rainwater flowing through the roof and the ground is mixed with pollutants such as sediment. If the rainwater in the countryside can be purified and further provided for the village's own water, it can be said to save a lot of resources. The rainwater purification pond is one of the specific forms of the ecological sponge city, and it is a new ecological environment model that emerged from the times. The rainwater purification pool gathers and absorbs rainwater from the roof or the ground, and through the comprehensive action of plants and sand, the rainwater is purified hierarchically and used for landscape water and rural water. It is an ecologically sustainable rainwater control and rainwater utilization facility. Compared with the traditional landscape pool, the landscape rainwater purification pool can give people a new landscape perception and visual experience.

At present, roads and roofs in rural areas discharge sewage through open or hidden channels, and finally flow into natural rivers, but it is easy to breed mosquitoes and produce odor, which affects environmental sanitation. Due to the limitation of drainage, it is easy to cause rivers The water level is too high, causing floods; open ditches or underground ditches can collect rainwater and use it for farmland irrigation, etc., but there is no way to help rainwater purification, nor can it realize the recycling of rainwater, let alone achieve the effect of saving resources and rational use.

By setting up sand sinking wells, first-level water purification tanks, second-level water purification tanks and third-level water purification tanks, rainwater is absorbed and purified layer by layer through various filter materials by means of stepped settlement and filtration, and gradually removes rainwater from roofs and roads. Impurities in rainwater solve the problem of rainwater drainage and filtration.

Through the emergency flood discharge channel set up at the position where the primary purification pool, the secondary purification pool and the tertiary purification pool are connected to the next-level pool, and at the position where the clean water pool is connected to the water outlet, when heavy rain or flood occurs, all levels When the water in the purification pool and the clean water pool exceeds the upper limit, it can be discharged into the emergency flood discharge channel, and discharged into the underground waterway through the bottom flood discharge pipe.

By setting the sand separation plate in the sand settling well, it can effectively block the large particle pollutants in the rainwater from the upstream, and play a preliminary separation role through the sedimentation; by setting different filter materials in the purification tanks at all levels, and Set up a filter pipe network at the connection of the purification pools at all levels, and gradually purify the water quality through filtration.

By setting the purification pools and stabilization pools at all levels as a structure whose height gradually decreases, the rainwater is automatically poured into the next-level pool by gravity.
