Description
Technical field：
The present invention relates to a kind of paper-making industry advanced waste treatment system, more particularly to a kind of place that advanced treating is carried out to waste water
Reason method, belongs to pulp and paper technology field.
Background technology：
With the water-saving and environmental protection requirement and the project verification requirement of new environmental protection project of paper-making industry, with the increase of quantity of circulating water, enter
The sewage quantity of Sewage Disposal is being gradually reduced, but the concentration of Pollutants in Wastewater accordingly increases, and according to calculating and predicting, is saved
After the water project implementation, inlet COD concentration can rise to 2300mg/l or so by original 2000mg/l.According to of the prior art
Sewage treatment process and treatment facility, it is difficult to reach the effluent quality formulated before the project implementation, to qualified discharge and improvement reclaimed water
Water quality brings certain difficulty.The subject matter that existing sewage disposal device is present has：1. pretreating effect is poor, the pond of preliminary sedimentation tank
Hold it is larger, because can not spoil disposal in time, precipitating sludge residence time in pond is longer, causes organic contamination in anaerobic acidification, waste water
The increase of thing content, increases follow-up biochemical treatment load；2. treatment process is lacked before oxygen consumption aeration, water quality, water can not be adjusted,
Cellulose and hemicellulose are difficult to degrade in waste water, and very big processing pressure is brought to follow-up biochemical process.
Waste water is after biochemical treatment, and the pollutant in water is mainly the solubilised state organic pollution for being difficult to biochemical degradation,
The solid particulate matter that free microorganism flco and part is not removed is also remained in waste water, it is necessary to further in-depth processing.
The content of the invention：
The technical problems to be solved by the invention are：A kind of paper-making industry advanced waste treatment system and its processing method are provided, it is right
Further depths reason is carried out in the waste water after biochemical treatment, water supply standard is reached.
The present invention is for the technical solution adopted for solving the technical problem：
A kind of paper-making industry advanced waste treatment system, including connected successively by pipeline coagulating basin, sedimentation basin, sand filter, sterilization
Pond and clear water reserviors, the coagulating basin upper end are provided with the first chemicals dosing plant, and the sedimentation basin upper end is provided with the second chemicals dosing plant,
The sterilization pool upper end is provided with the 3rd chemicals dosing plant.
Paper-making industry advanced waste treatment system recited above carries out the processing method of advanced treating to waste water, its specific step
It is rapid as follows：
1. the discharge of wastewater after biochemical treatment adds appropriate mix by the first chemicals dosing plant into coagulating basin into coagulating basin
Solidifying agent, regulation waste water pH value is 6.0~9.0；
2. the waste water emitted from coagulating basin is entered in sedimentation basin, is added by the second chemicals dosing plant to sedimentation basin appropriate
Decolorising agent, stands after stirring, and carries out separation of solid and liquid；
3. the waste water emitted from sedimentation basin is entered in sand filter, crosses the suspended material filtered to remove in waste water；
4. the discharge of wastewater emitted from sand filter is added suitable into sterilization pool by the 3rd chemicals dosing plant into sterilization pool
The disinfectant of amount, carry out disinfection processing；
5. the clear water emitted from sterilization pool, which is entered, carries out stewing process in clear water reserviors；
6. the clear water in clear water reserviors carries out cycling and reutilization through pumping to recycle-water point.
Described coagulant is industrial aluminum sulphate, and described decolorising agent is lipase, and described disinfectant is titanium dioxide
Chlorine.
The present invention using coagulant sedimentation carry out waste water advanced treating, be simple and convenient to operate with process, efficiency high,
The characteristics of small investment.Its general principle is：In the presence of coagulant, by compressing microparticle surfaces electric double layer, reduction interface ζ
The electrochemical process such as current potential, charge neutrality, and bridging, net such as catch, adsorbed at the physical and chemical process, by the suspension in waste water, glue
Body and the other materials that can be flocculated are condensed into " floc sedimentation "；The waste water after flocculation is subjected to separation of solid and liquid after being precipitated again through sedimentation basin,
" floc sedimentation " sinks to sedimentation basin bottom and as mud, top outflow is then colourity and the relatively low clear water of turbidity.It was verified that mixed
Solidifying removal of the precipitation method to suspension and colourity has preferable effect, while can also remove the COD of partial solubility.
Suspended impurity in water removal of the invention of being made a return journey using sand filter, is to ensure that the most terminal ring of water treatment system effluent quality
Section.
Conventional sterilization process has liquid chlorine, chlorine dioxide, ozone and disinfection by ultraviolet light.Ozone and ultraviolet have good
Disinfection Effect, but its equipment is expensive, and operating cost is higher, applies in general to require stricter place.Compared with liquid chlorine disinfection,
Chlorine dioxide antiseptic effect is good, offers medicine simple and convenient, is not influenceed by pH.Through Integrated comparative, present invention determine that using titanium dioxide
The disinfection way of chlorine.Chlorine dioxide is a kind of strong oxidizer, can rapidly be reacted with the organic matter in water after putting into water, make difficult life
The organic matter of thing degraded is decomposed into small molecule or is directly oxidized, so as to reduce the content of water pollutant, removes waste water color
Degree, while chlorine dioxide or a kind of very excellent disinfectant, have well for the coliform in water and various algae
Killing effect, the natural organic matter, Bu Huiyu such as humic acid (HA) or fulvic acid (FA) in chlorine dioxide energy direct oxidation water
It forms the chloride such as haloform, can substantially reduce after sterilization the chlorine disinfection by-product such as haloform (THMS) in water.
Clear water after processed by the invention rises to reuse water spot through pumping, it is impossible to the direct outer row of reuse, carries out farmland
Pour.
After advanced treating of the present invention, its effect is as follows（Referring to following table）：
Waste water after deep treatment of the present invention can also meet production process recycle-water while wastewater discharge standard is met
The requirement of water quality.
