Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to a synchronous water purification and algae removal boat. Background Art

[0002] At present, there are many kinds of water environment treatment agents on the market, but most of them are artificially scattered and made by manufacturers, which greatly limits the application of remote-use agents or water-based agents. At the same time, the impact of water transparency on the health of water bodies has become increasingly prominent. Low transparency leads to the inhibition of plant growth, and the water body develops from healthy to sub-healthy, which in turn affects the growth and reproduction of zooplankton, benthic animals, phytoplankton, etc.

[0003] The invention patent application with publication number CN114477395A, entitled A composite agent for efficient algae removal and simultaneous phosphorus removal and a method for algae removal and simultaneous phosphorus removal from water, discloses a composite agent composed of polyaluminum ferric silicate, potassium ferrate, and calcium peroxide, and specifically discloses the preparation method and use method of the agent. Example 4 discloses that the algae cell removal rate is 97% and the total phosphorus removal rate is 81.4%. Although this method can be applied to large areas of water, its use process is to spray the agent into the water body, and manual stirring is performed during the spraying process. The use is complicated and cumbersome, and it is also impossible to treat SS suspended matter in a targeted manner.

[0004] The invention patent application with publication number CN112624280A, entitled A sewage treatment device and application for enhanced coagulation to remove SS and TP, discloses a device capable of realizing continuous automatic treatment, which has three tanks for coagulation, flocculation and sedimentation, and can remove SS, TP and ammonia nitrogen in the water body, and the removal rates of the three can reach 94%, 80% and 42% respectively. However, the device cannot solve the algal bloom problem of the water body, and the treatment range is only near the water inlet, and the overall treatment effect on a larger area of ​​water body is limited.

[0005] In summary, it is of great significance to be able to remove eutrophication in large areas of water bodies while restoring water transparency and simultaneously treating algal blooms, SS, and nitrogen and phosphorus pollution, which requires the combination and coordination of multiple different means. Therefore, a synchronous water purification and algae removal ship is urgently needed to solve this problem. Utility Model Content

[0033] Example:

[0034] This example was conducted in the middle reaches of Huangjiatang in Ma'anshan City, where the river is about 10 meters wide and 1.5 meters deep. The experiment was conducted in early April 2022, when a blue algae bloom suddenly broke out in Huangjiatang, with a maximum chlorophyll concentration of 245 μg / L, total phosphorus of 0.45 mg / L, and ammonia nitrogen of 4.2 mg / L.

[0035] The hull is modified from a small boat. According to the scheme in the above specific implementation method, batteries, solar panels, algae removal chambers, SS removal chambers, nitrogen and phosphorus removal chambers, etc. are added. The YSI probe in the algae removal chamber is installed at the lower part, and the three chambers are used in series.

[0036] Initially, liquid pump 1 is turned on. Due to the poor water quality, the water inlet speed is controlled at a slow speed, with a flow rate of 10 cubic meters of water / h. The total iron ion concentration in the liquid in the algae removal chamber is maintained at about 5 mg / L by adding drugs and stirring. When the water level in the algae removal chamber reaches a certain height, liquid pump 2 is turned on. After water enters the SS removal chamber, flocculant is added. When the water level exceeds the liquid outlet and reaches a certain height, liquid pump 3 is turned on.
