Embodiment Construction

[0019] Fig. 1 to Fig. 3 have shown that for the preferred implementation process of the present invention is set, the polluted water body comprehensive purification method of the present invention mainly comprises the following steps:

[0020] The first step: on the bottom surface 1 of the river bed of the polluted river, the biofilm carrier soft filler 2 is arranged at equal intervals (such as 2M) and in parallel rows, such as by many parallel arrangements (made of crimped synthetic fiber silk) ) Braided curtain packing composed of braided strips, the bottom combination strip 6 of this kind of filler can be fixed in the river bottom with expansion bolts or stainless steel drills with barbs, and the upper combination strip is equipped with floats 4, so that the entire row The braided curtain filler 2 can be suspended in the river water after attaching a well-grown biofilm (see Figure 3).

[0021] The spacing setting range of two adjacent rows of braided curtain packing 2 is 0....

Abstract

The present invention discloses in-situ comprehensive polluted water purifying process including purifying water, reducing sludge and recovering and improving ecological system. The in-situ comprehensive polluted water purifying process includes the following steps: arranging parallel soft biomembrane carrier filler in the river bed of the polluted water, throwing specific bacteria strain capable of eliminating organic pollutant and sludge into the polluted water, and setting aerators in certain interval in the polluted water. The present invention can treat water pollution effectively.

Description

technical field [0001] The invention relates to a method for in-situ water purification, sludge reduction, and ecosystem restoration and improvement of polluted water bodies, especially a method for water purification, sludge reduction, and ecosystem restoration and improvement for polluted rivers-flowing water bodies In-situ comprehensive purification method of polluted water body. Background technique [0002] The existing in-situ purification and ecological restoration technologies for polluted water mainly use the addition of special-effect bacteria, or additional aeration and oxygenation, so that they can oxidize and degrade organic pollutants and remove nutrients such as nitrogen and phosphorus in an aerobic environment. This purification technology is only suitable for static polluted water bodies (such as landscape ponds and small lakes, reservoirs, etc.), because the added bacteria can remain in it and grow and reproduce under suitable conditions. However, this kin...
