A water restoration device with the function of separating algae and water

Abstract

The purpose of the present invention is to provide a water body restoration device with the function of separating algae and water. The device has a sealed tank. , the boiling point of the water in the sealed tank decreases, and then evaporates. At the same time, open the drain outlet at the bottom of the sealed tank to discharge part of the water in the tank into the water body. As the water level drops, the pressure in the sealed tank decreases, and the water body Continue to evaporate, the water vapor is condensed through the condensing equipment, the condensed water can be drunk after being filtered, and the non-condensable gas is recovered and treated at the same time, and the algae are discharged from the device under the action of chemicals and centrifugation, while the algae content and other polluting substances are kept in the sealed tank Continue to concentrate.

Description

technical field [0001] The invention relates to a water body restoration device, in particular to a water body restoration device with the function of separating algae and water. Background technique [0002] Due to the excessive development and utilization of environmental resources by human beings, a large amount of domestic sewage and industrial wastewater are discharged into natural water bodies without effective treatment, and eutrophication is becoming more and more serious. Under the conditions of sunlight, suitable water temperature and wind current, cyanobacteria can rapidly grow in large numbers in eutrophic water bodies, forming a layer of "blue" floating foam with a strong fishy smell on the water surface, that is, "bloom". After the cyanobacteria die and rot, they release toxins and produce stench, which will affect the water quality and cause human and animal poisoning. The scientific name of cyanobacteria is cyanotoxin, and the toxins in cyanotoxin are divide...

Problems solved by technology

The chemical method has the problem of chemical pollution due to the use of chemicals in the water area, which inevitably brings different degrees of harm to the water quality; the biological method is affected by environmental conditions and may also have a certain impact on the structure of biological groups and biodiversity, so it is difficult to Its effect is reflected in a short time; physical methods mainly include mechanical removal, biological aeration, and mechanical or manual net fishing to remove blue algae. Although the effect of direct net fishing is obvious, the mesh of the fishing net used is small due to the small size of the algae. , not only fish out blue-green algae but also bring out a lot of water when fishing with nets. Therefore, the fishing conditions are poor and the efficiency is low; the methods of removing blue-green algae in the water area by changing water, diverting water to wash away, and pumping away are relatively primitive and backward, and the cost is high , low efficiency, and it is a polluting move, which can easily cause secondary pollution

[0004] CN201136798Y uses a physical method to remove cyanobacteria in the water body, so that the algae cannot survive and be discharged into the water body after the cyanobacteria are broken, and algae toxins will still be produced during the cyanobacteria decay process, causing secondary pollution to the water body, which is difficult to fundamentally remove Algal toxins in water, studies have shown that in addition to being directly absorbed by the human body, algal toxins may also be absorbed by the human body through the food chain, threatening human health
