(4) two stage treatment pretreatment：The pH value of waste water is determined, pH value is adjusted using sulfuric acid or NaOH, by pH value
It is adjusted in the range of 7～8；
(5) resin is selected：Using middle polarity macroporous absorbent resin；
(6) adsorb：By waste liquid with 3～4BVh-1Desorption flow flow through polymeric adsorbent, the temperature of absorption is 30～40
℃；
(7) desorption is processed：Desorption process is carried out to the polymeric adsorbent after absorption using methyl alcohol, the temperature of desorption is 30～40
DEG C, desorption flow is 1.23～4BVh-1。
Described resin is carrying out being pre-processed using front needs.
Described pretreatment is specially cleans the resin for preparing to use using 30～40 DEG C of hot water repeatedly；It is 4 with concentration
～5% sodium hydroxide solution slowly flows across resin, is flow through with 2 times per hour of bed volume；With the salt that concentration is 4～5%
Acid solution flows through resin, is flow through with 1.5 times per hour of bed volume；Tree is flow through with the sodium hydroxide solution that concentration is 4～5%
Fat；Deionized water rinse to go out water ph value for 6～7 when, you can use.
The ozone dosage 1-2mg/L that described ozone sterilization is, the duration is 5～10 minutes, and temperature is 15～25
Between DEG C.Sterilized effect is good.
To last layer starch in sedimentation basin during described precipitation, in the upside of sedimentation basin one layer of starch film is formed.Formed and formed sediment
Powder film, is easy to precipitation.
Described middle polarity macroporous absorbent resin when not in use, using drinks and is added after the mixed liquid dipping of salt
Storage.Prevent middle polarity macroporous absorbent resin season cracking and aging.
The present invention carries out sterilization, sterilization, filtration etc. using the method for physics, will not cause secondary dirt to the sewage for filtering
Dye, the present invention strictly controls Ph values during sewage disposal, is easy to the more preferable absorption of middle polarity macroporous absorbent resin.
