High-efficiency purification system integration process for algae, suspended matters and total phosphorus in landscape water body

Abstract

The invention relates to a purification system integration process for algae, suspended matters and total phosphorus in a landscape water body. By applying the mechanisms of physical and chemical adsorption precipitation, physical magnetic adsorption, high-efficiency magnetic separation purification and centrifugal solid-liquid separation comprehensively, substances such as algae, suspended matters, total phosphorus and the like in water are adsorbed by a flocculating agent, a coagulant aid and magnetic seeds to form a flocculate, wherein the flocculate has the super-magnetism and is adsorbed by a magnetic drum of a high-efficiency magnetic separation device in the water, and adsorbates on the surface of the magnetic drum are removed by a continuous sludge scraper, namely the algae, the suspended matters, the total phosphorus and the like in the water are removed by purification and separation; and simultaneously, scraped sludge enters a sludge storage room through centrifugal separation and dehydration. The sewage purification process has the advantages of short residence time, high speed and small floor area, and realizes the high-efficiency and quick purification of water bloom substances such as the algae, the suspended matters and the total phosphorus in the landscape water body to control water quality in the water body effectively and avoid eutrophic phenomenon caused by alga propagation in the water body.

Description

technical field [0001] The invention discloses an integrated process for purifying algae, suspended solids and total phosphorus in a high-efficiency landscape water body, and belongs to the technical field of purifying sewage water bodies. Background technique [0002] At present, water pollution and water shortage have become common problems faced by all countries in the world, especially for developing countries. Taking my country as an example, with the rapid economic development, people's living standards are constantly changing, but the ensuing pollution problems are also intensifying, and a large amount of domestic sewage is discharged into the city without treatment or does not meet the discharge standards. water, leading to eutrophication and algal blooms. A large amount of nitrogen and phosphorus nutrients enter the water body, which promotes the vigorous growth of autotrophs. With the development of eutrophication, the number of individual algae increases rapidly,...

Problems solved by technology

Using chemical agents to remove algae, additional chemical substances are artificially added to the water body. Although the algae are removed, the remaining chemical substances pose a high threat to the water environment.
