Problems solved by technology

Patents: 200720075459.3 and 200820150439.2 respectively disclose two kinds of immobilized submerged plant water purification devices, which have the characteristics of convenient harvesting and management, and effectively avoid the secondary pollution caused by the presence of submerged plant residues in the water. The purification effect of water plants to absorb nutrients such as nitrogen and phosphorus is obviously insufficient, and the treatment performance needs to be further improved

Abstract

The invention relates to an ecological net packing device, which consists of rope nets, combined packing units, floating balls, sleeves, fixing rods and submerged plants. The combined packing units are fixed on knots of the rope nets; a sandwich structural mode is adopted, and the matched submerged plants are sandwiched and fixed between two rope nets; the upper ends of the rope nets are connected with the floating balls, and two sides of the rope nets are fixedly connected with the sleeves through side fixing lines; and in the using process, fixing rods are inserted into the sleeves on the two sides, and the two fixing rods are respectively inserted into water body riverbed or lakebed so as to fix the ecological net packing in water. The ecological net packing device has the characteristics of good water quality purifying effect, simple structure, convenient processing and transportation, no blockage or caking, simple installation, convenient management and maintenance, strong current impact resistance and the like, and can be used for in-situ purification of natural water bodies such as riverways and lakes and artificial water bodies.

Description

technical field [0001] The invention belongs to the field of novel environmental protection technology, and in particular relates to an ecological net packing device used for in-situ purification treatment of natural water bodies and artificial water bodies. Background technique [0002] With the rapid development of society and economy, the pollution of water environment is becoming more and more serious, and more and more natural water bodies appear eutrophication. Water eutrophication has become a worldwide environmental problem. At present, there are many kinds of eutrophic water restoration technologies. From the perspective of technical principles, these technologies can be divided into physical methods, chemical methods and biological methods. Due to the common problems of high cost, unstable effect and easy to produce secondary pollution in physical and chemical methods, people have paid special attention to bioremediation technology. Biological contact oxidation in...
