Problems solved by technology

At present, the common polyvinyl chloride biofillers on the market have insufficient hydrophilic properties and bio-affinity, resulting in insufficient film-hanging speed, film-hanging amount, and tightness between the film and the filler. It is expected to improve the mass transfer, film formation and water treatment performance of the filler by adding appropriate substances to it for blending modification.
In addition, the impact strength of vinyl polymer filler is only 2-5kJ / m 2 , has the disadvantages of low impact strength and poor thermal stability, which lead to the aging of the filler and the short service life

Abstract

The invention relates to a multi-component biological packing for increasing biofilm culturing quantity and a preparation method thereof. The multi-component biological packing is prepared from the following raw materials in parts by weight: 20-60 parts of polyamide, 30-50 parts of humus, 10-25 parts of polyvinyl alcohol, 80-150 parts of carbon nanofibers, 0.5-1 part of oxalic acid, 10-20 parts oflignin, 10-20 parts of activated carbon and 5-25 parts of diatomite. The preparation method particularly comprises the following steps: uniformly mixing all the raw material components; injecting theobtained mixture into a feed hopper of an injection molding machine; and performing extrusion molding by a packing mould to obtain the multi-component biological packing. The multi-component biological packing for increasing the biofilm culturing quantity is suitable for microbial growth, is quick in biofilm culturing speed and large in bio-film quantity.

Description

technical field [0001] The invention belongs to the technical field of domestic wastewater treatment, and in particular relates to a multi-component biological filler for increasing the film-hanging amount and a preparation method thereof. Background technique [0002] Biological filler is one of the cores of wastewater biological treatment technology. Its hydrophilicity and bio-affinity will directly affect the attachment and growth of microorganisms, thereby affecting the treatment effect of wastewater. At present, the common polyvinyl chloride biofillers on the market have insufficient hydrophilic properties and bio-affinity, resulting in insufficient film-hanging speed, film-hanging amount, and tightness between the film and the filler. It is expected to improve the mass transfer, film formation and water treatment performance of the filler by adding appropriate substances to it for blending modification. In addition, the impact strength of vinyl polymer filler is only ...
