Problems solved by technology

There are two main disadvantages in the in-situ water purification method of ordinary filler biofilm water bodies: 1. The filler mainly uses artificially prepared organic polymer materials as the base material, which is relatively expensive. The aging filter material and the algae produced will cause environmental pollution Secondary pollution, and its treatment and disposal are extremely difficult, posing a potential hazard to the environment
2. Since the artificially prepared organic polymer materials will release a lot of dissolved substances when they are submerged in polluted water for a long time, the environmental toxicology research is not thorough and comprehensive.
Organic polymer filter material is easy to age and fall off, easy to pollute, easy to block, and expensive, easy to form secondary pollution
Due to the high density, small specific surface area and small porosity of quartz sand in natural inorganic filter materials, when sewage flows through the filter layer, the resistance is very large and the biomass is small, so it is not used much now.

Embodiment Construction

[0012] A method for in-situ water purification of polluted water, comprising the following steps: 1). Process the mature fruit or semi-ripe fruit of the natural plant loofah into a loofah; fix the loofah 3 and the rope 2, and the upper end of the rope 2 and the floating rod 1 is fixed, the lower end of the rope 2 is fixed with the pendant 4, and the floating rod is tied with 4 ropes, and each rope is strung with 2 loofahs to form a sewage in-situ purification device; 2). Put the sewage in-situ purification device into Into the in-situ water of the polluted water body, the loofah is immersed in the in-situ water of the polluted water body, and the floating rod floats on the in-situ water surface of the polluted water body; the active microbial cells in the in-situ water of the polluted water body quickly (within 2-5 days) in the loofah Active dynamic biofilm is formed on the outer surface of the biofilm, and the sewage can be purified around the dynamic biofilm. The sewage in-si...

Abstract

An in-situ cleaning method for the polluted water system includes such steps as providing luffa, tying them to floating rods via strings, tying a weight to said floating rod, arranging them in the water to make the luffa be suspended in water, and treating for 6-9 days.

Description

technical field [0001] The invention relates to an in-situ water quality purification method for polluted water bodies. Background technique [0002] At present, the common in-situ water purification methods of biofilm water are mostly to use various fillers, bacteria and algae in the water to form a biofilm system, and perform in-situ purification of the polluted water around the biofilm module to improve water quality and curb water body enrichment. Nutritization trend, effectively preventing the occurrence of "algae blooms" and "red tides" in polluted water bodies. There are two main disadvantages in the in-situ water purification method of ordinary filler biofilm water bodies: 1. The filler mainly uses artificially prepared organic polymer materials as the base material, which is relatively expensive. The aging filter material and the algae produced will cause environmental pollution Secondary pollution, and its disposal is extremely difficult, posing a potential hazard...
