Abstract

The invention belongs to the field of water treatment materials, and relates to a preparation method and application of a water treatment material based on typha orientalis presl. The preparation method is characterized by performing chemical modification on the natural typha orientalis presl and comprises the specific process of cleaning, drying, grinding, chemical modification and the like of the typha orientalis presl. The water treatment material has the advantages of being purely natural and degradable, being recycled for 10 times through simple acid / alkaline treatment, and having a high adsorption capacity, which is 94.7 times that of the natural typha orientalis presl which is not modified, to lead ions in water solution. The water treatment material not only can be used for treating lead-ion-contained waste water in water treatment plants, but also can be applied to household water filters, thus having wide market prospect.

Description

technical field

[0001] The invention belongs to the technical field of water treatment materials, and in particular relates to a preparation method of a cattail grass-based water treatment material and its application in treating lead-containing wastewater. Background technique

[0002] Cattail grass, whose scientific name is Typha orientalis Presl, mostly grows by itself in watersides or ponds, and is widely distributed in East China and South China. The uses of rush grass include: (1) used to decorate garden pools, lakesides, and construct waterscapes; (2) used as materials for making artificial cotton and paper; (3) important materials for weaving straw mats, straw sandals, straw hats and other traditional utensils.

[0003] Lead-containing wastewater comes from various battery workshops, mineral processing plants, petrochemical plants, etc. The battery industry is the most important source of lead-containing waste water, and every production of a battery causes at leas...
