Abstract
The invention relates to a method for treating waste liquor with a floating coagulation method, and belongs to the field of waste liquor treatment. According to the method for treating the waste liquor with the floating coagulation method, the waste liquor is treated through the coagulation method, in the process of treating the waste liquor, flocculating constituent obtained through coagulation floats to the surface of the waste liquor, and then sheets having the function of adsorbing the flocculating constituent and arranged on the surface of the waste liquor are used for adsorbing the flocculating constituent. The floating coagulation method can increase the probability of contact between the flocculating constituent and colloidal matter, and the time for water body clarifying is shorter than that of free sedimentation.
Description
Technical field
The present invention relates to a kind of method utilizing floating type Coagulation with Treatment waste liquid, belong to field of waste liquid treatment.
Background technology
Coagulation is one of cell process of many water treatment procedures, directly affects equipment investment and operating cost.Coagulation Method
It is the isolation technics to colloidal attitude pollutant, refers under the effect of coagulant, make the colloid in waste liquid and fine suspension cohesion
Become floccule body, the water treating method being then separated off.Coagulation Method application in liquid waste processing is the most widely, and it is main
Want equipment to have coagulant and the mixing channel of waste liquid hybrid reaction process and reaction tank, and complete what water separated with floccule body
Sedimentation tanks etc., its equipment investment is bigger.
Summary of the invention
For solving above-mentioned technical problem, the present invention provides a kind of method of floating type Coagulation with Treatment waste liquid, and floating type mixes
Solidifying method can save the investment of the aspect such as equipment, construction, and has process time short advantage.
The method utilizing floating type Coagulation with Treatment waste liquid, is the method utilizing Coagulation with Treatment waste liquid, is disposing waste liquid
During, the floccule body making coagulation obtain floats up to waste liquid surface, and what recycling was arranged at waste liquid surface has adsorption-flocculation
The sheet material floccule body of body function.
Floating type Coagulation Method of the present invention refers to when with Coagulation with Treatment waste liquid, arranges and have absorption in reaction tank
The sheet material of floccule body function so that it is be suspended in waste liquid surface.When carrying out liquid waste processing, the floccule body making coagulation obtain floats up to
Waste liquid surface, floccule body is brought to behind waste liquid surface by sheet-adhesion, float and glue in the adsorbable water of floccule body being attached
The Organic substances such as figure.
In technique scheme, preferably described in have the sheet material of adsorption-flocculation body function be filter cotton.Mistake of the present invention
Filter pulp is for having adsorption function filter cotton, and it has the function of adsorption-flocculation body, commercially available.Floccule body after adhesion and mistake
Synergism is had, such as: process the same volume surfactant with concentration with the polyaluminum sulfate aluminium flocculating agent of same amount between filter pulp
Waste water, the effect of floating type Coagulation Method is better than conventional Coagulation Method,
Further, it is preferable to described filter cotton to be synthetic fibers filter cotton, non-woven fabrics filter cotton, glass fiber filter cotton or
Activated carbon filter cotton.
Further, described filter cotton can retain the particle diameter material more than 5 μm, and the thickness of filter cotton is 0.3～20mm.
The floccule body that the preferred described method of floating type Coagulation Method of the present invention makes coagulation obtain by stirring or air-blowing method
Float up to waste liquid surface.
Utilization stirring or air-blowing method make waste water form eddy current, and after forming eddy current, floccule body is brought to quilt behind waste liquid surface
Sheet-adhesion, the Organic substance such as float and colloidal attitude in the adsorbable water of floccule body being attached.
The invention have the benefit that
1) in conventional Coagulation Method, floccule body only plays a secondary net and catches adsorption, and the adsorption of floccule body is the most fully sent out
Wave, and floating type Coagulation Method can increase the touch opportunity of floccule body and colloidal attitude；
2) time that floating type Coagulation Method makes water body clarify is shorter than free style sedimentation；
3) can avoid using for the Sedimentation tank separated with waste liquid by floccule body, reduce equipment investment.Filter cotton can be repeatedly
Use, and be convenient for changing.
Detailed description of the invention
Following non-limiting example can make those of ordinary skill in the art that the present invention be more fully understood, but not with
Any mode limits the present invention.
Test method described in following embodiment, if no special instructions, is conventional method；Described reagent and material, as
