Composite biomaterial for treating wastewater

Abstract

The invention discloses a composite biomaterial for treating wastewater. The biomaterial is characterized by comprising the following substances by weight: 14 to 20 parts of PA, 3 to 14 parts of PB, 14 to 26 parts of PE, 5 to 9 parts of nitric acid, 4 to 6 parts of sodium hydroxide, 3 to 7 parts of potassium hydroxide, 1 to 8 parts of calcium hydroxide, 1 to 3 parts of a nanoparticle inorganic material, 2 to 7 parts of calcium carbonate, 1 to 6 parts of calcium sulfate, 1 to 4 parts of diatomite, 2 to 4 parts of an acrylic fiber and 3 to 9 parts of an anti-aging agent. A preparation method for the composite biomaterial is simple; the composite biomaterial is easy to manufacture; through processing of the composite biomaterial with a mold, the composite biomaterial has a rough surface and a plurality of micropores, so the composite biomaterial has a large specific surface area, can improve the wetting performance of a filling material, is more beneficial for biofilm culturing of microbes and is capable of substantially improving the biofilm culturing speed and fastness of microbes in a water treatment system.

Description

technical field [0001] The invention relates to a wastewater treatment composite biological material. Background technique [0002] Typical fillers on the existing market, such as Longtai Environmental Protection (Filler) Co., Ltd., which specializes in producing various environmentally friendly water treatment fillers, are made of PE, which has a high bulk density and relatively poor suitability for the growth of biofilms. However, the existing disclosed technology fails to comprehensively consider the performance of fillers: including hydrophilicity (suitable for the growth of biofilms), suitable for the growth of aerobic, facultative and anaerobic bacteria, the specific gravity of fillers, and the materials used Cost and durability of use, etc. Chinese patent CN1740102 discloses an integrated flocculation biological fluidized bed sewage treatment process, for the purpose of integrating the first-level enhanced technology and biological fluidized bed technology, the flocc...
