Description

Filling combined filler

Technical Field

The utility model relates to a natural water body administers technical field, has and is a packing combination filler.

Background

Along with the rapid development of cities, the pollution degree of natural water is increased and the original ecological system of the water is destroyed, the self-purification capacity of the water is reduced along with the reduction of the types and the number of the original microorganisms in the water, and the key for improving the self-purification capacity of the water is to strengthen the types and the number of the original microorganisms in the water. The lack of microorganisms can cause the total quantity of pollutants contained and eliminated in the water body to be reduced, and the water quality index of the water body is continuously deteriorated without being effectively improved. If aerobic microorganisms in the water body are absent or insufficient in quantity, the concentration of organic pollutants can be directly increased, the original healthy water body is changed into a black and odorous water body, the black and odorous phenomenon is caused for a long time, so that bottom sludge is changed into black and odorous bottom sludge, the natural water body is polluted internally, and the water ecological structure at the bottom of the water body is damaged. Therefore, the method can be used for improving the self-purification capacity of the water body and effectively absorbing the exogenous pollutants in time, and is an important measure for ensuring the long-term sustainable development of the using function of the water body.

The method provides more attachment places and growth spaces for the original microorganisms of the natural water body and enables a plurality of indigenous microorganisms to propagate in a large quantity. The microbial carriers applied to natural water bodies are various in types, but the effective contact area between the carriers and the water bodies is low, the types of the installed biological carriers are single, the survival and attachment rate of microbes on the carriers is low, formed biological membranes are easy to age and fall off, the treatment of the natural water bodies cannot achieve the expected design effect, and meanwhile, the microbial carriers are not easy to install and are easy to damage in the natural water bodies. At present, the biofilm carrier that uses the most is spiral biofilm carrier of rope type and blanket form biofilm carrier, and these two kinds of filler installation engineering volume are big, water shock resistance is very poor, and in the natural water body that flows, biofilm carrier can be emptyd along with rivers, becomes horizontal water contact mode by original vertical water contact mode, has reduced biofilm carrier and water effective area of contact, and when the flow grow of natural water body, the filler can shake off fixing device and float downstream along with rivers, has destroyed the water self-purification system of putting up.
