Problems solved by technology

For the existing biomass microbial carriers such as straw, most of them use biomass directly as the carrier. Although it has strong biophilicity and short film-hanging time, it has poor durability and fast degradation, so it is not suitable for sewage treatment. Long-term hanging film treatment

Abstract

The invention discloses a method for preparing a biomass microbial carrier. The method comprises the following steps: smashing a biomass to obtain particles of 50 to 200 mesh; adding a polyethylene raw material according to the proportion of 10 to 90 percent; mixing the raw materials to be uniform; weighing 2 to 20 g of the mixture for a single piece; putting the weighed mixture into a mold; pressing for 1 to 15 minutes under 5 to 40 MPa; demoulding; carrying out thermal shaping for 10 to 80 minutes at 140 to 160 DEG C; taking out the shaped product; cooling to obtain a biomass microbial carrier sample. The method is simple in process and low in product cost, and is a new method for preparing a high-load durable biological film carrier simply and easily; the product can be used in the microbe treatment technology of various special waste water, and has a wide market prospect.

Description

technical field [0001] The invention relates to a method for preparing a biomass microbial carrier, which belongs to the technical field of resources and environment technology. Background technique [0002] In the water treatment method, the biofilm method is a method of sewage treatment using microorganisms (ie, microbial films) attached to and growing on certain solid surfaces. In recent years, it has been widely used in wastewater treatment due to its advantages of high treatment efficiency, impact load resistance, stable operation, small sludge output, economy and energy saving. Biofilm is an ecosystem composed of highly dense aerobic bacteria, anaerobic bacteria, facultative bacteria, fungi, protozoa and algae. The solid medium to which it is attached is called filter material or carrier. The carrier is the core part of the biofilm process and plays an important role in the aerobic, facultative and anaerobic processes. The material of the carrier, the specific surfa...
