Embodiment 1

[0022] The embodiment of the present invention provides a nano-bubble green water dialysis technology, comprising the following steps:

[0023] 1) First use the biofilm to conduct preliminary dialysis on the water body, make a blend solution of PVDF, hydrophilic polymer and solvent, and then immerse the liquid film of the solution in a non-solvent to obtain a hydrophilic modified film, thereby Remove a large number of detergents, petroleum and other components that inhibit the growth of algae in sewage, as well as trace heavy metal elements;

[0024] 2) Then put a certain proportion of environmental protection regulators into the water body, increase light intensity, oxygen and other measures to create an environmental condition that is conducive to the rapid growth of algae, so that the algae can quickly grow nitrogen and phosphorus in the water in an artificially controlled system. The elements are absorbed to form a huge amount of biofilm to pretreat the water body;

Abstract

The invention provides a nano-bubble green and environment-friendly water body dialysis technology, and relates to the technical field of water body dialysis. According to the invention, the method comprises the following steps: 1) performing preliminary dialysis on a water body by using a biological membrane, preparing a blended solution from PVDF, a hydrophilic polymer and a solvent, and immersing and precipitating a liquid membrane of the solution in a non-solvent to obtain a hydrophilic modified membrane, thereby removing a large amount of components such as a detergent and petroleum for inhibiting the growth of algae, trace heavy metal elements and the like in sewage; nano bubbles are generated through a nano foaming machine; and the small bubbles from the nanometer level to the micron level have physicochemical properties such as a crushing phenomenon, an ionization phenomenon, an ultrasonic property, an electrification property, diffusivity, oxidability, stability, bactericidalactivity, retentivity, physiological activity, self-pressurization property and the like which are not possessed by conventional bubbles, have extremely strong water body treatment capacity, and cannot generate new water body pollution at the same time.

Description

technical field [0001] The invention relates to the technical field of water body dialysis, in particular to a nano-bubble green and environment-friendly water body dialysis technology. Background technique [0002] According to the classification of sewage sources, sewage treatment is generally divided into production sewage treatment and domestic sewage treatment. Production sewage includes industrial sewage, agricultural sewage and medical sewage, while domestic sewage refers to the sewage generated in daily life, which refers to the complex mixture of various forms of inorganic and organic substances. Sewage treatment is to make the sewage discharge into a certain water body or The quality of water for reuse requires a process of purifying it. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly ...
