Detailed Description

As shown in the figure, the water body in-situ ecological restoration device comprises a water pump, a water inlet 1, an ejector 3, a fluidized bed 4 and a water outlet 5 which are sequentially connected through a pipeline assembly 2, wherein the ejector 3 is further connected with an ozone generator 6, equipment water is pumped by the water pump and then enters the ejector 3 through the water inlet 1 of the equipment, after the ozone generator 6 generates ozone, water and air flow through nozzles in the ejector at high speed to generate a vacuum suction effect, and the ejector 3 mixes the ozone and the water generated and conveyed by the ozone generator 6 and then flows into the fluidized bed 4. After the post-treatment of the fluidized bed 4, the water returns to the original position after flowing out, and the device has wide application range, low energy consumption and high purification efficiency.

Ozone has several advantages: can kill virus and spore with strong chlorine resistance; the influence of the pH value and the temperature of the sewage is small; removing pollutants such as color, odor, taste, phenol, chlorine and the like in the sewage, increasing dissolved oxygen in the water and improving the water quality; the biodegradability of sewage is improved; easy decomposition in water, no secondary pollution caused by residue, etc.

The water inlet 1 is also connected with a security filter 7, the other end of the security filter 7 is connected with an ozone generator 6, and water in the security filter 7 enters the ozone generator 6 to be used as cooling water, so that the normal use of the ozone generator 6 is ensured.

The 2 fluidized beds 4 are connected side by side and are internally distributed with ceramic particles with different particle sizes and scientific proportions as biomembrane carriers, water passes through the two fluidized beds 4 from bottom to top and then is treated, the water returns to the original position after flowing out, and the two fluidized beds 4 can better treat the water of the equipment.

The active filler adopts ceramsite with different grain diameters and scientific proportion. According to different sewage properties, a plurality of trace elements which are beneficial to the rapid attachment and growth of microorganisms are fused in the material, and the material is modified and constructed by a special process, and has the advantages of large specific surface area, good hydrophilicity, high bioactivity, rapid film formation, good treatment effect, long service life and the like. Designing a geometric configuration according to hydromechanics and strengthening the surface adhesion capability; the specific surface area of the filler is large, and the attached biomass is large; no support is needed, fluidization is easy, energy consumption is saved, and occupied area is saved; the processing capacity and effect are improved by increasing the filling rate, and no new structures are needed. The active filler of filler science ratio can make the pollutant degrade fast, improves water microbial activity, accelerates biochemical reaction, and the formation of food chain and the growing environment of high-end biology are improved fast through the rapid propagation of low end microorganism, the effect of "food chain" is accelerated greatly: the ammonia nitrogen and the total phosphorus are reduced, and the transparency and the dissolved oxygen are increased.
