Eutrophic water body phycomycete symbiosis purification technique

Abstract

The invention relates to a eutrophic water body phycomycete symbiosis purification technique which comprises the following steps: feeding an effective biological bacterium into a polluted water body through a bacterium feeding system, subsequently feeding into a medicine feeding system, adding coagulant aids into the medicine feeding system, subsequently treating by using a multi-stage shallow water purification device, and filtering the treated water to remove nitrogen and phosphorus, thereby obtaining purified water. By adopting the purification technique, the eutrophication of the polluted water body can be effectively controlled, a V-type water quality water body of surface water can be rapidly purified into a III-type water quality water body, a basic environment is provided for aquatic plants and aquatic animals, water body functions are finally recovered, a water ecological cleaning system is established, the water resource is saved, the air quality is improved, the sensing effect of people is improved, the water ecologic environment quality is improved, remarkable ecologic environment benefits can be obtained, and thus the purification technique is significant for healthy development of local social economy.

Description

technical field [0001] The invention relates to a symbiotic purification technology of algae and bacteria in eutrophic water body. Background technique [0002] Eutrophication refers to the fact that under the influence of human activities, a large amount of nutrients such as nitrogen and phosphorus required by organisms enter slow-flowing water bodies such as lakes, estuaries, and bays, causing algae and other plankton to multiply rapidly, and dissolved oxygen in water bodies The amount of water has declined, the water quality has deteriorated, and fish and other organisms have died in large numbers. When eutrophication occurs in water bodies, phytoplankton algae multiply and form algae blooms. Due to the different colors of the dominant phytoplankton, the water surface often appears blue, red, brown, milky white, etc. This phenomenon is called red tide or red tide in the ocean. Eutrophication will affect the water quality of the water body, and will reduce the transpare...

Problems solved by technology

Simply using physical methods to remove algae is relatively simple, quick and has no side effects, but its disadvantage is that the action time is short and cannot fundamentally solve the problem
