Red tide treatment device for protecting marine ecological environment

Abstract

The invention discloses a red tide treatment device for protecting a marine ecological environment. The device comprises a tank body, wherein a fixed block is arranged at the top of the outer wall ofone side of the tank body, and connecting springs are distributed on one side, far from the tank body, of the fixed block in an equal interval manner; connecting rods are arranged at one ends, far from the fixed block, of the connecting springs, and a mounting plate is arranged at one ends of the connecting rods; second movable rods are arranged at two ends of the bottom of one side of the mounting plate, and extension sleeves are arranged at two ends of the bottoms of the outer walls of two sides of the tank body; and draining holes are formed in the inner walls of the bottoms of the extension sleeves in an equal interval manner, and the inner walls of the draining holes are obliquely arranged. According to the red tide treatment device, clay powder in the tank body is moved to an unloading hole, so that the clay powder is not accumulated in the tank body; discharging holes are dredged in a reciprocating manner by virtue of anti-blocking needles, so that the blockage of a dischargingnet plate is effectively prevented, the situation that the clay is accumulated on the mounting net plate is effectively avoided, the rapid settling of the clay is promoted, and the treatment efficiency of red tide is improved.

Description

technical field [0001] The invention relates to the technical field of marine ecological environment, in particular to a red tide treatment device for marine ecological environment protection. Background technique [0002] Red tide is an ecological abnormal phenomenon caused by certain microalgae, protozoa or bacteria explosively proliferating or gathering to a certain level under certain environmental conditions, causing water discoloration or causing harm to other organisms in the ocean. The disasters that all countries are facing, how to detect and deal with red tide disasters and reduce economic losses as much as possible have become the focus of research by coastal countries. [0003] The current treatment methods for red tide disasters include chemical methods, physical methods or biological methods. The chemical methods are divided into direct killing method and coagulant precipitation method. The flocculants used include inorganic flocculants, organic flocculants and...

Problems solved by technology

[0003] The current treatment methods for red tide disasters include chemical methods, physical methods or biological methods. The chemical methods are divided into direct killing method and coagulant precipitation method. The flocculants used include inorganic flocculants, organic flocculants and microbial flocculants. Among them, the natural mineral flocculation method is to use natural mineral flocculants including clay minerals, silicic acid, silicate, zeolite, polyaluminum chloride or aluminum sulfate to kill red tides. Among them, clay minerals have rich sources, low cost, and no Pollution and strong adsorption, the applicability of other natural mineral flocculants is far inferior to the clay mineral treatment method, but the clay mineral treatment method has too fast coagulation, which leads to limited ability to precipitate red tide organisms. Currently, clay minerals are spread on the red tide sea surface after red tide It is difficult for organisms and the flocs they produce to settle to the bottom of the sea in time, resulting in low efficiency and poor effect of red tide treatment
