Abstract
The present invention provides a kind of yarn dye wastewater treatment techniques, the yarn dye wastewater treatment processing step is as follows: step 1: coagulant and flocculation aid being added into waste water, waste water solid is separated by coagulant, then reinforces the effect of separation of solid and liquid by flocculation aid；Step 2: the waste water after the completion of separation of solid and liquid is screened the solid in waste water by sieve；Step 3: being added pH regulator in the waste water completed to screening, be adjusted by acid-base property of the pH regulator to waste water, handles active carbon is added in the waste water after the completion of adjusting；Step 4: pH detection is carried out to the waste water after the completion of active carbon processing；Step 5: it will test after qualified waste water is screened again by sieve and be discharged；It will test underproof waste water and directly turn again to step 3 and operated；The present invention also improves working efficiency by carrying out postsearch screening to waste water to substantially increase the quality of wastewater treatment.
Description
Technical field
The present invention relates to yarn dye wastewater treatment technology field more particularly to a kind of yarn dye wastewater treatment techniques.
Background technique
At present in yarn dyeing, when needing to handle the waste water after dyeing, and waste water being handled at present,
The processing for standing decoloration is generallyd use, but above-mentioned processing mode cannot be handled the waste residue having in waste water, be easy to lead
Cause wastewater treatment unclean, time-consuming relatively long and inefficiency.Therefore solve the problems, such as that waste water treatment efficiency is low and time-consuming long just shows
It obtains particularly important.
Summary of the invention
In view of the above-mentioned problems, the object of the present invention is to provide a kind of yarn dye wastewater treatment techniques, by into waste water
Coagulant and flocculation aid is added to sieve to being separated by solid-liquid separation in waste water, then by sieve to the waste residue after separation of solid and liquid
Choosing, the waste water after the completion of screening carry out acid-base property adjustment to it by pH regulator, live to being added in the waste water after the completion of adjustment
Property charcoal carry out absorption and clean waste water, pH detection finally is carried out to the waste water after the completion of processing, detect qualified waste water again into
The screening of row sieve also improves work effect by carrying out postsearch screening to waste water to substantially increase the quality of wastewater treatment
Rate.
To solve the above problems, the present invention provides a kind of yarn dye wastewater treatment technique, at the yarn waste water from dyestuff
Steps are as follows for science and engineering skill:
Step 1: coagulant and flocculation aid being added into waste water, separates waste water solid by coagulant, then by flocculation aid come
Reinforce the effect being separated by solid-liquid separation；
Step 2: the waste water after the completion of separation of solid and liquid is screened the solid in waste water by sieve；
Step 3: being added pH regulator in the waste water completed to screening, be adjusted by acid-base property of the pH regulator to waste water,
It is handled active carbon is added in the waste water after the completion of adjusting；
Step 4: pH detection is carried out to the waste water after the completion of active carbon processing；
Step 5: it will test after qualified waste water is screened again by sieve and be discharged；It is direct to will test underproof waste water
Step 3 is turned again to be operated.
Further improvement lies in that: the metallic sieve that the sieve in the step 2 is 0.15 ~ 1mm.
Further improvement lies in that: the step 1 is into step 3 toward addition coagulant, flocculation aid, pH regulator in waste water
It is required to be stirred when with active carbon.
Beneficial effects of the present invention: by coagulant and flocculation aid being added into waste water come to progress solid-liquid point in waste water
From, then by sieve the waste residue after separation of solid and liquid is screened, the waste water after the completion of screening carries out it by pH regulator
Acid-base property adjustment carries out absorption and clean waste water to active carbon is added in the waste water after the completion of adjustment, finally to processing after the completion of
Waste water carry out pH detection, detect qualified waste water and carry out sieve screening again, by carrying out postsearch screening to waste water to big
The quality for improving wastewater treatment greatly, also improves working efficiency.
Specific embodiment
In order to deepen the understanding of the present invention, the present invention will be described in further detail with reference to the examples below, the embodiment
For explaining only the invention, it is not intended to limit the scope of the present invention..
A kind of yarn dye wastewater treatment technique is present embodiments provided, the yarn dye wastewater treatment processing step is such as
Under:
Step 1: coagulant and flocculation aid being added into waste water, separates waste water solid by coagulant, then by flocculation aid come
Reinforce the effect being separated by solid-liquid separation；
Step 2: the waste water after the completion of separation of solid and liquid is screened the solid in waste water by sieve；
Step 3: being added pH regulator in the waste water completed to screening, be adjusted by acid-base property of the pH regulator to waste water,
It is handled active carbon is added in the waste water after the completion of adjusting；
Step 4: pH detection is carried out to the waste water after the completion of active carbon processing；
Step 5: it will test after qualified waste water is screened again by sieve and be discharged；It is direct to will test underproof waste water
Step 3 is turned again to be operated.
The metallic sieve that sieve in the step 2 is 0.15 ~ 1mm；The step 1 into step 3 toward in waste water plus
It is required to be stirred when entering coagulant, flocculation aid, pH regulator and active carbon.
By the way that coagulant and flocculation aid are added into waste water come to being separated by solid-liquid separation in waste water, then by sieve to solid-liquid
Waste residue after separation is screened, and the waste water after the completion of screening carries out acid-base property adjustment to it by pH regulator, to having adjusted
Active carbon is added in waste water after and carries out absorption and clean waste water, pH detection, inspection finally are carried out to the waste water after the completion of processing
It surveys qualified waste water and carries out sieve screening again, by carrying out postsearch screening to waste water to substantially increase the matter of wastewater treatment
Amount, also improves working efficiency.
