A eutrophication sewage purification simulation system

Abstract

The invention relates to an eutrophication sewage purification simulation system which comprises a water tank with an open upper side surface, a first water pump and a plurality of aquatic plants, wherein the water tank is provided with a water inlet and a water outlet; the first water pump is arranged on one side of the water tank; the water outlet pipe is communicated with the water inlet and used for pumping sewage into the water tank by the first water pump; and the aquatic plants are grown in the sewage in the water tank. The water purification is carried out in the water tank, on the ground or in the water body; and thus, the water purification can be carried out on the ground, and can also be used as a mobile minitype sewage treatment system. The in-situ test is converted into the mobile water purification mode capable of maximally simulating the real sewage environment, thereby obtaining the more accurate aquatic plant sewage purification rule.

Description

technical field [0001] The invention relates to the field of environmental protection equipment, in particular to a eutrophic sewage purification simulation system. Background technique [0002] A large number of aquatic plants such as water hyacinth can purify eutrophic water bodies. The root exudates of water hyacinth can damage the chloroplasts, mitochondria and other organelles of Scenedesmus, significantly reduce the ability of photosynthetic oxygen release, and seriously affect the growth of algae. , the content of soluble protein in algae cells almost plummeted, making it difficult to restore the damaged photosynthetic system. At the same time, studies have also shown that water hyacinth root exudates also have a certain bactericidal effect, which can greatly reduce the number of saprophytic bacteria and E. coli in the surrounding environment. The other side of water hyacinth is that it is easy to flood and cause the water body to be completely covered by it, which e...

Problems solved by technology

The other side of water hyacinth is that it is easy to flood and cause the water body to be completely covered by it, which eventually leads to the deterioration of the entire ecological environment of the water body; the existing technology is configured in a laboratory environment when studying the operation rules of water purification operations using aquatic plants Sewage or raw water extracted from sewage sources for in-situ tests, the corresponding research results have large deviations due to the differences between the above simulation methods and the real sewage environment
