Artificial wetland in use for processing polluted water

Abstract

This invention discloses an artificial wetland for sewage disposal, which comprises a first water-distribution zone, a second water-collection zone, artificial substrate, a first water-distribution pipe network in the first water-distribution zone, s second water-collection pipe network in the second water-collection zone, and plants growing on the artificial substrate. Compared with present techniques, the invention extends the first water-distribution pipe network into the artificial substrate, which can directly introduce wastewater onto the artificial substrate, and raise the utility of the artificial substrate. The invention has such advantages as advanced technology, reliable technique, high efficiency, low energy consumption, no blockage and no pollution.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an artificial wetland for sewage treatment. Background technique [0002] With the development of industry, water pollution has become more and more serious. At the same time, the contradiction between the shortage of fresh water resources and the improvement of people's living standards has become increasingly serious, and the task of water environment protection has become more and more difficult. In recent years, environmental science research has been developing rapidly, and the global effect of water pollution is being actively explored. Various methods of water treatment pollution emerge in an endless stream. Among them, the sewage ecological treatment technology-constructed wetland technology, due to its low cost, good effluent quality, and easy operation Simple, easy maintenance, low construction, maintenance and operation costs (only 1 / 10 to 1 / 2 of traditional s...

Problems solved by technology

However, the water distribution system and water collection system of the artificial wetland, the water distribution area and the water collection area are vertically arranged in the pool body, and become an independent partition in the pool body. In this way, the sewage enters from the facade of the artificial matrix, and A non-horizontal surface will inevitably cause more sewage on one side of the artificial matrix and less on the other side, that is, the uneven distribution of sewage, which directly reduces the utilization rate of the artificial matrix, and the purification effect of sewage is not ideal.

[0005] On the other hand, the sewage contains a lot of impurities and silt. When it flows through the pipes in the water distribution system and is distributed into the artificial matrix, these impurities and silt are easily left in the pipes, which will cause pipe blockage and affect the use. Generally, it is necessary to artificially extract the pipeline to flush and clean it separately, which is troublesome and increases the maintenance workload

In the existing constructed wetlands, the design of the pipelines in the water distribution system has not considered its flushing function
