Water purifying device for plate and frame biological filtering dam

Abstract

The invention provides a water purifying device for a plate and frame biological filtering dam. The water purifying device for the plate and frame biological filtering dam comprises an upstream filtering dam, a downstream filtering dam and at least one filter material filling frame, wherein the upstream filtering dam is fixed at the upstream base of a riverway, and the downstream filtering dam is fixed at the downstream base, a preset distance far away from the upstream filtering dam, of the riverway; a water inlet hole is formed in the upstream filtering dam; a water draining hole is formed in the downstream filtering dam; a containing slot used for containing the filler material filling frame is formed between the upstream filtering dam and the downstream filtering dam; the filler material filling frame is movably contained in the containing slot; and a filling matrix which can roll in the filter material filling frame and has filtering and adsorption effects is filled in the filter material filling frame. The water purifying device for the plate and frame biological filtering dam is high in water purifying efficiency and easy to maintain, can be easily attached by a biological membrane and is resistant to water impact.

Description

technical field [0001] The invention relates to a water purification device, in particular to a plate and frame biological filter dam water purification device. Background technique [0002] Urban rivers are an essential element for the survival and development of cities, and play a very important role in the economic development and ecological protection of cities and surrounding areas. With the acceleration of urbanization and urban modernization in today's society, the wealth created by human beings and human beings are more and more closely concentrated in cities, and the city's dependence on water resources and the disasters that floods may cause to cities are becoming more and more serious. Therefore, the improvement of urban water environment has been paid more and more attention by all sectors of society. People have transformed from the traditional concept of water conservancy construction of flood control and drainage to the concept of building a "safe, comfortable...

AI Technical Summary

Problems solved by technology

[0004] The existing similar biological filler water purification device is directly and integrally fixed at the bottom of the river, so this biological filler water purification device is easily repeatedly and frequently impacted by the flowing water in the river channel, so it is easy to be damaged, and at the same time, because the biological filler water purification device is directly integrated It is fixed at the bottom of the river, so it cannot be easily taken out for cleaning after the water purification device is blocked, so its operating cycle is short
