In the above methods, the clogging of the filter screen often occurs, which seriously affects the filtration efficiency. In order to solve the problem of clogging, it is often necessary to stop the machine for backwashing
However, the method of adding flocculants (such as patents CN200810024721.0, CN201410382658.3, etc.) is not only expensive, but also produces algae mud that is not conducive to subsequent resource utilization.
Therefore, for a long time, the problems of high energy consumption, small processing capacity and difficult treatment of algal pulp have become important factors restricting the mechanical harvesting of lake cyanobacteria blooms

Embodiment 1
[0031] A method for removing algae by microfiltration of a marine rotary drum, the steps are:
[0032] A. Algae extraction: the drum microfiltration algae removal machine is assembled on the barge platform, and the water pump draws algae water from the algae-rich water area of the lake, and transports the algae water into the drum through the pipeline connected to the water inlet of the algae removal machine;
[0033] B. Water filtration: The drum is covered with a filter screen. When the drum rotates, the water in the algae water is filtered by the filter screen under the action of gravity and centrifugal force, and flows out from the screen holes on the side of the drum to obtain filtered water, which is discharged through the drainage outlet;
[0034] C. Algae interception: the algae in the algae water are intercepted by the filter, attached to the filter, and leave the water body with the rotation of the drum;
[0035] D. Algae flushing: When the algae trapped in the fil...
Embodiment 2
[0038]A marine drum microfiltration algae removal device, which consists of a water inlet 1, a clean water outlet 2, a drum driving motor 3, a backwashing water pump 4, an algae slurry outlet 5, an inspection window 6, a drum 7, a filter screen 8, Algae discharge pipe 9, algae collection tank 10, backwash pipe 11, backwash nozzle 12, rotating sealing frame 13, water baffle 14, box body 15, water inlet area 16, water filtration area 17, spoke structure hollow shaft 18 , an electric control box 19, a frequency converter 20, an air switch 21, and a touch screen 22. Its connection relationship is: the water inlet 1 is installed on the lower side of the water inlet area 16 at the front end of the box body 15, and the clean water outlet 2 is installed on the lower side of the water filter area 17 at the rear end of the box body 15; the water inlet area 16 and the water filter area 17 are formed by The water baffle 14 is separated, the water baffle 14 is sealed and connected with the...

Abstract
The invention discloses a method and a device for removing alga by means of micro-filtration by the aid of drums for ships. The method includes steps of A, drawing the alga, and to be more specific, mounting a micro-filtration algae removing machine with the drums on a photon; B, filtering water, to be more specific, covering the drums with filter screens, filtering the water in algae water by the aid of gravitational force and centrifugal force; C, retaining the alga in the algae water by the filter screens; D, flushing the alga from the filter screens by the aid of backwash water from filtered clear water; E, collecting the flushed alga by algae collecting tanks arranged in barrels and discharging the alga via an algae discharge pipe. A water inlet is formed in the lower side of a water inlet zone at the front end of a tank, a clear water outlet is formed in the rear end of the tank, inlet water and filter water are partitioned by a water partition plate, the filter water is pumped into a backwash pipe by backwash water pumps, backwash spray nozzles are arranged on the backwash pipe, and maintenance windows are mounted at two edges of the upper portion of the tank; frequency converters and air switches are mounted in an electric control box and are connected with a touch screen by electric wires. The method and the device have the advantages that good algae removal effects can be realized, and the method and the device are applicable to collecting and removing blue-green alga with different concentrations in lakes; the alga in water can be quickly and efficiently harvested by the aid of the method and the device on a large scale.
Description
technical field [0001] The invention belongs to the technical fields of water body algae filtration and environmental protection. More specifically, it relates to a method for removing algae by a marine drum microfiltration, and also relates to a device for removing algae by a marine drum microfiltration, which is suitable for collecting and removing cyanobacteria in lakes, reservoirs and other water bodies. Background technique [0002] There are many ways to control lake cyanobacterial blooms, including physical, chemical and biological methods. Chemical algae killing is quick but lasts for a short time, and it is easy to cause secondary pollution and damage the water ecological environment, so it is generally used with caution in natural water bodies. Biological methods include biological manipulation, algae-dissolving bacteria, and algae-dissolving virus to control algae. When used in large lake water bodies, the effect is slow and the success rate is not high. The phy...
