Description
Technical field
The present invention relates to a kind of preparation method of flocculant, in particular to a kind of sodium metasilicate modified hydrophobic cellulose base flocculation
The preparation method of agent, belongs to technical field of polymer materials.
Background technique
Flocculation sludge is as the by-product generated in sewage treatment, and complicated component, water content is higher, in usual primary sedimentation tank
The water content of activated sludge can achieve 99% or more, this volume that will lead to sludge becomes larger, and dehydration is difficult, after being unfavorable for
Reason increases post processing cost.And a large amount of water-containing sludge is arbitrarily accumulated and will cause microbial growth, so as to cause the production of disease
It is raw, while underground is penetrated into, it will affect the water quality of underground water.Therefore, handled flocculation sludge has been when previous necessary
It faces and solves the problems, such as.
In water treatment procedure, flocculant because its is at low cost, effect is good, simple process due to become at current main waste water
Manage medicament.Due to inorganic flocculating agent there are secondary pollution, dosage is big the problems such as, then by organic wadding with outstanding flocculating property
Solidifying agent replaces.But traditional organic flocculant the disadvantages of that there are still biodegradabilities is poor, residual toxic monomers.Natural polymer
Sub- flocculant because it has many advantages, such as that source is wide, at low cost, renewable, biodegradable, pollution-free, increasingly by academic and
The favor of industry.
The invention proposes a kind of preparation methods of sodium metasilicate modified hydrophobic cellulose base flocculant.Using abundance,
Cheap bamboo cellulose is raw material, is crushed, dissolution becomes the cellulosic molecule of dispersion, through initiation, graft copolymerization and inorganic
Object hydrophobically modified finally obtains sodium metasilicate modified hydrophobic cellulose base flocculant.
