Biological active carbonized straw/kieselguhr molecular sieve manganese removing filter material

Abstract

The invention discloses a biological active carbonized straw / kieselguhr molecular sieve manganese removing filter material. Straw and kieselguhr are used as base stock of the filter material, the production cost is reduced, polyethyleneimine is used for crosslinking the base stock to introduce manganese oxidizing bacteria, and the filter material with the long-acting dynamic adsorption manganese removing effect is obtained. Polyethyleneimine has a certain manganese ion adsorbing function to accelerate breeding and growth of the manganese oxidizing bacteria, and the interception capacity of the filter material is further promoted. The filter material has a unique nano molecular sieve structure, and compared with a traditional filter material, the manganese removing filter material has the prominent advantages in the production cost and manganese removing effect and has good application prospects in treatment on a drinking water source with manganese content slightly exceeding standards.

Description

technical field [0001] The invention relates to the technical field of water treatment materials, in particular to a bioactive carbonized straw / diatomite molecular sieve filter material for removing manganese. Background technique [0002] At present, most cities in my country have or gradually use reservoirs and lakes as the main source of urban water supply. Therefore, reservoirs and lakes play an important role in water source cities. Reservoirs and lakes are closely related to human life and production. The source of water and production water, lake water also plays a significant role in regulating the natural environment. However, in summer, with the occurrence of reservoir stratification events and hypoxia at the bottom of the reservoir, manganese in the pore water migrates to the overlying lake water, redox The boundary layer moves up into the reservoir, causing a large amount of manganese in the sediment to be released to the overlying water body, and the dissolved Mn ...

The article "Research on the Adsorption and Removal of Manganese Ions in Water by Nano Molecular Sieve and Diatomite" explores the use of nano molecular sieve and diatomite as filter materials to achieve a relatively ideal manganese removal effect, but its removal effect is greatly affected by the pH value of the system , will also change the pH value of the system, a large amount of use will cause the pH of drinking water to not meet the standard, and its adsorption capacity is effective, so it is not suitable for large-scale use
