Description

Purifier of high organic waste content landscape water body

Technical Field

The invention belongs to the field of water treatment, and particularly relates to a purification device for a landscape water body with high organic waste content.

Background

In recent years, with the increasing and increasing demands of scenic water bodies in commercial districts, office places, high-grade residences, parks and the like, how to effectively and economically treat and maintain the water quality of the scenic water bodies becomes a problem to be solved urgently. In the approach of exploring the landscape water treatment method, the method goes from a circulating filtration method simulating swimming pool water treatment to a strain throwing method and an aeration method simulating sewage treatment, and the most economical and effective solution approach for landscape water treatment is realized by establishing and perfecting an aquatic ecosystem of the landscape water body so that the landscape water body has a self-purification function.

At present, the research on the landscape water treatment by the domestic ecological method is mostly focused on the investigation of the species and community proportion of organisms in the wild water body, and then various aquatic plants, strains, zooplankton, fish and benthonic animals are planted in the landscape water body according to the proportion according to the investigation result.

The growth of the aquatic weeds can absorb a large amount of nutrients such as nitrogen and phosphorus in the water body. However, the use of underwater lawns also has its limitations because the photosynthesis of underwater lawns requires sunlight, and therefore the water body needs to have a certain degree of transparency before the underwater lawns are thrown; meanwhile, the stable bacterial colony can decompose organic matters in water and convert part of substances which are toxic to water into substances which are harmless or can be safely utilized by aquatic plants.

The water body which is not polluted in the wild environment has a perfect water body ecological system which is gradually formed in the long-term historical evolution process, and if the landscape water body can establish the perfect ecological system similar to the natural environment, the self-purification of the landscape water can be completely realized; however, most artificial landscape water bodies have small fields and single ecosystems, complete animal and plant and even microorganism-participated decomposition and purification chains are difficult to form, so the artificial ecological purification system which is usually built with great investment cost can play an ideal effect, and the maintenance cost is high.

For most landscape water management parties without the high cost and maintenance expense, it is a realistic approach to establish stable and benign cycles of plants and microorganisms at a lower cost through appropriate, simple manual intervention.

In view of the above, there is a need for an economical and effective purification device or treatment method for landscape water with high organic waste content, which has controllable manufacturing, installation, modification, maintenance and other costs.
