Embodiment Construction

[0024] The content of the present invention will be specifically described below in conjunction with the embodiments.

[0025] In order to solve the problems of long film-hanging time, less film-hanging amount and short service life of ordinary biological fillers, research has been carried out on how to increase the film-hanging speed of microorganisms on fillers and improve the service life of fillers for raw materials for making biological fillers. .

[0026] The invention provides a composite biological filler, comprising the following components in mass ratio:

[0027]

[0028]

[0029] During the biological treatment of sewage, some metal ions are essential elements for the growth and reproduction of microorganisms, and are very important for the cultivation of microorganisms. The present application has found through specific research that when some metal ions are in an appropriate concentration range, the synthesis of cells can be accelerated and the process of b...

Abstract

The application relates to a compound biological filler and a preparation method thereof. The compound biological filler and the preparation method thereof comprises the following components in parts by weight: 0.1 to 1.0 part of calcium sulfate, 0.1 to 0.6 parts of nickel dichloride, 0.05 to 0.5 parts of cobalt sulfate, 0.01 to 0.06 parts of copper sulfate, 0.01 to 0.1 parts of ferric chloride, 0.05 to 0.5 parts of magnesium sulfate, 0.002 to 0.11 parts of titanate coupling agent and 100 parts of polypropylene. Biofilm formation on the compound biological filler is faster, so that the debugging of a sewage treatment system can be more quickly finished, and thereby the sewage treatment system can be more quickly put into operation. Moreover, both the tensile strength and impact strength of the compound biological filler are greatly increased in comparison with the tensile strength and impact strength of conventional biological fillers.

Description

technical field [0001] The invention relates to a biological filler used in a sewage treatment process, more specifically, to a composite biological filler and a preparation method thereof. Background technique [0002] The filler is the place where the biofilm lives, is the carrier of the biofilm, and also has the function of intercepting suspended matter. Therefore, the filler is the key to the biofilm sewage treatment process, which directly affects the efficiency of the biofilm sewage treatment process. The requirements of the filler are: easy biofilm attachment, large specific surface area, large porosity, small water flow resistance, high strength, good chemical and biological stability, durable, strong ability to retain suspended substances, no harmful substances dissolved, and no secondary Pollution, the specific gravity is not much different from that of water, avoiding overloading of the oxidation pool, and convenient transportation and construction. [0003] At ...
