Description

Rainwater purification all-in-one machine

technical field

The utility model relates to a rainwater treatment device, in particular to a rainwater purification integrated machine.

Background technique

Waterlogging is a prominent problem in the process of urban construction and development in my country, especially in the rainy south, where waterlogging is more serious. The main reason is that urban construction uses a large amount of hard ground to replace the natural ground with permeable capacity. When it rains, the water permeability is not good, which leads to the accumulation of rainwater, which impacts the drainage pipe network and causes a large amount of waterlogging. One of the ways to solve urban waterlogging is to build a sponge city with natural accumulation, natural infiltration, and natural purification functions. Carry out low-impact development of urban rainwater systems, build ecological drainage facilities, and give full play to the role of urban green spaces, roads, and water systems in absorbing, storing, and slowing release of rainwater. By collecting, purifying, storing and utilizing rainwater runoff, it reduces the impact of rainwater runoff on the pipe network, effectively alleviates urban waterlogging, and at the same time achieves the purpose of saving water resources, protecting and improving the urban ecological environment.

The traditional rainwater treatment process mostly uses solid-liquid separators. The rainwater treatment equipment is relatively complex, has certain requirements for the site, requires regular maintenance, and is more complicated to operate and manage. The existing equipment for collecting and processing rainwater runoff still has many deficiencies in terms of integration and integration. For example, Chinese Patent Publication No. 204233856U discloses an integrated rainwater processor, which includes a rainwater filter, a water storage tank, a lift pump, and connecting pipelines. However, each device of the rainwater treatment device is openly connected, and all devices are not arranged in a container, which increases the difficulty of construction and is inconvenient for maintenance and management. In addition, Chinese Patent Publication No. 204208345U discloses a buried rainwater treatment device, which includes a water inlet and outlet and double-layer filter packing. However, the treatment device is not equipped with disinfection equipment, which cannot guarantee the quality of the effluent after rainwater treatment.
