Filter-well circulating purification system and method for purifying river by using same

Abstract

The invention relates to a filter-well circulating purification system and a method for purifying river by using the same. The system consists of a filter bed, water filter pipes, a collector pipe, a filter well, a submersible pump and a connection pipeline, wherein a mortar stone masonry wall is formed at the periphery of the filter bed, and an erosion preventing layer, a filter material layer and a bearing layer are arranged inside a stonewall sequentially from top to bottom; the collector pipe is arranged on the middle part of the bearing layer horizontally, and one end of the collector pipe passes through the stonewall closed to one side of a river bank and is connected with the filter well; a plurality of openings are formed on both sides of the collector pipe, and each opening is connected with one water filter pipe; the water filter pipes are arranged on the middle part of the bearing layer horizontally; a plurality of open holes are formed on each water filter pipe; the filter well is arranged outside a riverway, and the bottom surface of the filter well is lower than a river bed; and the submersible pump is arranged at the bottom of the filter well, and a water outlet of the submersible pump is connected with an upstream riverway by a pipeline. After being filtered by the filter material layer, the river is collected to the filter well outside the riverway by the water filter pipe and the collector pipe, is pumped by the submersible pump and is conveyed to the upstream of the filter well by the pipeline, so that a water body in the riverway is filtered, purified and circulated.

Description

technical field [0001] The invention relates to a water body purification technology, in particular to a river water filtration cycle purification treatment technology. Background technique [0002] With the rapid development of the national economy, the pollution and eutrophication of rivers and lakes are becoming more and more serious, especially the pollution of urban rivers is more concerned by government departments at all levels and the people. Polluted river water generally has the following characteristics: 1. The amount of water that needs to be treated is large, and it is generally impossible to carry out long-distance transportation, and the method of on-site purification is used; 2. Generally, the land resources on the river bank are tight, so it is impossible to use a long-term treatment time and complicated process. 3. Due to the large amount of water, the process with high treatment cost cannot be used, and the problem of secondary pollutants brought by the tr...

Problems solved by technology

Polluted river water generally has the following characteristics: 1. The amount of water that needs to be treated is large, and it is generally impossible to carry out long-distance transportation, and the method of on-site purification is used; 2. Generally, the land resources on the river bank are tight, so it is impossible to use a long-term treatment time and complicated process. 3. Due to the large amount of water, the process with high treatment cost cannot be used, and the problem of secondary pollutants caused by the treatment process must be considered

[0003] Currently known river water purification methods include physical methods, chemical methods, and biological methods. However, many of the above-mentioned treatment measures have the characteristics of high technical requirements, complicated construction, and huge investment, so it is difficult to implement them on a large scale.

In addition, with the reduction of water resources and the increase of water prices, the supplementary water volume of landscape water bodies in various parks, hotels, residential areas and other places is gradually limited; due to the particularity of the functions of these places, the use of conventional water control methods is limited, so this Water quality management and maintenance problems of quasi-water bodies are becoming more and more prominent
