Problems solved by technology

However, compared with natural bacteria micelles, the existing artificial bacteria micelles have insufficient permeability and low adsorption efficiency, and it is difficult for organic pollutants with large molecular weight to enter the inside of bacteria micelles, which affects the further improvement of the treatment efficiency of organic pollutants.
[0005] At the same time, the existing single-matrix artificial bacteria micelles have the problem of insufficient stability, and are easily affected by factors such as sewage temperature, pH, charge, and heavy metal concentration to decompose, dissolve, and lose microorganisms, resulting in shortened service life. The biofilm dissolved in the sewage will lead to secondary pollution and increase the difficulty of sewage treatment

Abstract

The invention discloses an artificial zoogloea which comprises the following raw materials in parts by weight: a first polymer matrix, a second polymer matrix, a third polymer matrix, a zoogloea framework, a toughener, a first adsorbent, a second adsorbent and the balance of deionized water. The artificial zoogloea has the advantages of stable properties, high degradation efficiency of organic pollutants, low sludge yield and low tendency to secondary pollution, and is applicable to high-concentration organic wastewater treatment, natural water body in-situ restoration and sludge treatment.

Description

technical field [0001] The invention relates to water pollution treatment technology, in particular to an artificial bacteria micelle and a preparation method thereof. Background technique [0002] In water pollution (including sludge in waters) treatment projects, biodegradation is generally used to remove organic pollutants such as protein, fat, and aromatic compounds in sewage. Existing biodegradation methods applied to sewage treatment include activated sludge method and biofilm method. [0003] The activated sludge method uses the aerobic microorganisms attached to the activated sludge to oxidize and degrade the organic pollutants in the sewage under the condition of aeration. The cost is low, and it has a large application scale in China. The biofilm method is to cultivate microorganisms on the solid surface, so that they naturally form a film-like substance composed of microorganisms, and then use this substance to treat sewage, which has the advantages of simple ope...
