Description

Technical Field

[0001] The utility model relates to the technical field of water purification, in particular to an algae-containing water purification system. Background Art

[0002] The proliferation of cyanobacteria is a global aquatic environmental problem. With the interference of human activities, global warming and eutrophication of water bodies, surface cyanobacteria accumulate in a certain area and form cyanobacterial blooms driven by wind. Their massive reproduction changes the physical and chemical properties of water and causes pollution. In addition, cyanobacteria release organic matter, nitrogen and phosphorus into the water during the apoptosis process, accelerating the eutrophication of water bodies. At the same time, the toxins they produce release odor into the water and produce foreign matter on the surface of the water, causing damage to water resources and affecting the growth of aquatic plants and animals.

[0003] In recent years, biological methods have been widely used in cyanobacteria control due to their energy-saving and environmental protection characteristics. Submerged plants play an important role in the ecological stability of eutrophic rivers and lakes. Some chemical substances released by plants are the main reason for inhibiting the growth of cyanobacteria. The secreted allelopathic substances can inhibit the growth of Microcystis aeruginosa by destroying the structure of cyanobacterial cells, affecting photosynthesis and enzyme activity. As a relatively safe ecological cyanobacteria control technology, it can be used to control cyanobacterial blooms.

[0004] Studies have shown that there is a two-way "low-promoting, high-inhibiting" phenomenon between algae and submerged plants in water bodies, that is, when the concentration of algae in water bodies is low, it can promote the growth of submerged plants, and when the concentration of algae in water bodies is high, it can inhibit the growth of submerged plants; when the planting density of submerged plants is low, it can promote the production of algae, and when the planting density of submerged plants is high, it can inhibit the production of algae. Therefore, it is necessary to plan the planting density of submerged plants in a targeted manner according to the algae concentration of the water source. However, most of the existing algae-containing water purification pools are integrated and cannot be graded for different algae densities, resulting in poor water purification effects. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide an algae-containing water purification system, which can plan the graded planting density of submerged plants in different chambers in the planting pool according to the degree of blue algae outbreak in eutrophic algae-type lakes and rivers, etc., and has good water purification effect, good growth of submerged plants, and better landscape effect.

[0006] In order to solve the above-mentioned technical problems, the technical solution of the utility model is a purification system for algae-containing water, including an algae-water separation tank and a planting tank; the algae-water separation tank is connected to the bottom of the planting tank; a plurality of layers of partitions are installed in the algae-water separation tank; a plurality of algae-water separators are installed on each layer of partitions, and a through hole is opened on each layer of partitions; a plurality of partitions are arranged in the planting tank, and the partitions divide the planting tank into a plurality of chambers; a plurality of drainage holes are opened at the bottom of the partitions.

[0007] Furthermore, the algae-water separation pool is separately arranged from the planting pool, and a pipeline is installed between the water outlet of the algae-water separation pool and the water inlet of the planting pool.

[0008] Furthermore, the algae-water separation pool is arranged adjacent to the planting pool, and the water outlet of the algae-water separation pool is the water inlet of the planting pool.

[0009] Furthermore, the water outlet of the planting pool is opened at the upper part of the side away from the algae-water separation pool.

[0010] Furthermore, the horizontal positions of the through holes formed on two adjacent partitions are staggered.

[0011] Furthermore, the number of the partitions is at least three; and the number of the algae-water separators installed on the partitions decreases from top to bottom.

[0012] Furthermore, the number of the partitions is at least two.

[0013] Beneficial effects of the utility model:

[0014] The present application sets up a connected algae-water separation pool and a planting pool, and installs an algae-water separator in the algae-water separation pool to separate part of the blue algae, effectively reducing the concentration of blue algae entering the planting pool, and dividing the planting pool into several chambers, and the density of submerged plants planted in each chamber decreases from close to the algae-water separation pool to far away from the algae-water separation pool. The utility model adopts a combination of physical and biological methods. After the blue algae in the water body are physically separated, they are inhibited by biological methods, which can effectively prevent a large concentration of blue algae from directly entering the planting pool, causing damage to the submerged plants, resulting in an insignificant treatment effect. According to the degree of blue algae outbreaks in eutrophic algae-type lakes, rivers, etc., the graded planting density of submerged plants in different chambers in the planting pool can be planned in a targeted manner, with good water purification effect, good growth of submerged plants, and good landscape effect.

The algae-water separator is an existing technology, which uses a water pump to suck the algae-containing water into the equipment, and discharges the water after separating the blue algae.

[0021] From left to right, the density of cyanobacteria in the first chamber of the cultivation tank is 8×10 5 cell / ml, and the planting density of submerged plants is 2000g / m 3 The density of cyanobacteria in the second chamber is 4×10 5 cell / ml, and the planting density of submerged plants is 1500g / m 3 The density of cyanobacteria in the third chamber is 8×10 4 cell / ml, and the planting density of submerged plants is 1000g / m 3 .

[0022] The above algae-containing water purification system is provided with an algae-water separation pool 1 and a planting pool 2 which are connected to each other, and an algae-water separator 8 is installed in the algae-water separation pool 1 to separate part of the blue algae, effectively reduce the concentration of blue algae entering the planting pool 2, and divide the planting pool 2 into a number of chambers, and the density of submerged plants planted in each chamber decreases from close to the algae-water separation pool 1 to far away from the algae-water separation pool 1. The utility model adopts a combination of physical and biological methods, and the blue algae in the water body are physically separated and then inhibited by biological methods, which can effectively prevent a large concentration of blue algae from directly entering the planting pool 2, causing damage to the submerged plants, resulting in an insignificant treatment effect. The application can plan the graded planting density of submerged plants in two different chambers in the planting pool in a targeted manner according to the degree of blue algae outbreak in eutrophic algae-type lakes, rivers, etc., with good water purification effect, good growth of submerged plants, and good landscape effect.

[0023] Specifically, the algae-water separation pool 1 is separately arranged from the planting pool 2, and a pipe 6 is installed between the water outlet of the algae-water separation pool 1 and the water inlet 10 of the planting pool 2. The algae-containing water of the water source is introduced into the algae-water separation pool 1 by a water pump, and the algae-containing water first enters the algae-water separation pool 1 on the top layer, and the algae-water separator 8 separates part of the blue algae, and then enters the next layer through the through hole 7, separating the blue algae layer by layer, so that the concentration of the blue algae finally entering the planting pool is effectively reduced.

[0024] Specifically, the water outlet 5 of the planting pool 2 is opened at the upper part of a side away from the algae-water separation pool 1 .

[0025] Specifically, the horizontal positions of the through holes 7 opened on two adjacent partitions 9 are staggered, which can prevent the water body from falling vertically to the bottom, thereby improving the separation rate of blue algae.

[0026] Specifically, the number of algae-water separators 8 installed on the partition 9 decreases from top to bottom.

[0027] Example 2

[0028] Specifically, Figure 2 As shown, the connection mode between the algae-water separation pool 1 and the planting pool 2 is different from that in Example 1, and the rest of the structures are the same as those in Example 1. Specifically, the algae-water separation pool 1 and the planting pool 2 are arranged adjacent to each other, and the water outlet of the algae-water separation pool 1 is the water inlet 10 of the planting pool 2.

[0029] Working principle of this utility model:

[0030] The algae-containing water body of the water source is introduced into the algae-water separation pool 1 through a water pump. The algae-containing water body first enters the algae-water separation pool 1 on the top layer. The algae-water separator 8 separates part of the blue algae, and then enters the next layer through the through hole 7, and separates the blue algae layer by layer, so that the concentration of the blue algae finally entering the planting pool is effectively reduced. Then the water body first enters the chamber with a relatively high density of submerged plants in the planting area, and after a certain degree of purification, it enters the other chambers on the right side with a decreasing density of submerged plants in turn. The utility model adopts a combination of physical and biological methods. The blue algae in the water body are physically separated and then inhibited by biological methods, which can effectively prevent a large concentration of blue algae from directly entering the planting pool 2, causing damage to the submerged plants, resulting in an insignificant treatment effect. The application can plan the graded planting density of submerged plants in 2 different chambers in the planting pool in a targeted manner according to the degree of blue algae outbreak in eutrophic algae-type lakes, rivers, etc., with good water purification effect, good growth of submerged plants, and good landscape effect.
