Abstract
The present invention is a kind of nano-high molecule carboxymethyl chitosan sanitary sewage disposal medicament and processing method, is related to technical field of waste water processing, is made of the component of following weight percentage：15 25 parts of carboxymethyl chitosan, 5 10 parts of sodium alginate, 5 10 parts of mandruka graphene, 25 30 parts of chaff ketone resin, modified 15 20 parts of seaweed acidic group fiber, etc..Modification of chitosan based sols of the present invention, using fiber as the molding carrier of modification of chitosan based sols, nano-titanium dioxide is grafted on surface and increases its surface area ratio, the poly- silicon fluoride of inorganic cation is used in high surface area outer layer, Electrostatic Absorption is formed with organic anion polyene acid amides, ensure that stability and fixing of the material on the basis of high surface area ratio.By the method, and add medicament and multistage abatement processes are carried out to sanitary sewage, positive effect, realize recycling for water resource.
Description
Invention field
The invention belongs to technical field of waste water processing, relates in particular to a kind of nano-high molecule carboxymethyl chitosan life
Sewage treatment drug and domestic sewage processing method.
Background technology
With the increase of wastewater treatment rate and processing depth, sludge discharge is in the speed increasing with annual more than 10-15%
It is long, but supporting specific resistance to filtration is but without acquirement greater advance.Due to the reasons such as technology, policy, most domestic city
City's sewage sludge is all to utilize landfill stabilization mode, does not carry out harmless treatment, the secondary pollution problem of sludge is extremely serious.
A large amount of landfills of high water content sludge cause to take valuable land resource, so that many cities can not find landfill yard.Sludge oozes
Filtrate becomes the pollution sources of underground water in many areas, and landfill yard also then becomes air into mosquito breeding ground, landfill gas
Pollution sources.Developed country's specific resistance to filtration such as Europe and North America progressively turns to the resource recycling profit based on sludge drying
Based on, burning gradually reduces, and the ratio of Sludge landfill is gradually reduced, or even forbids sludge landfill.And sludge drying is
Sludge realizes innoxious, minimizing, the key link of recycling treatment disposal.
