Description
Technical field
The present invention relates to sewage treatment fields, and in particular to a kind for the treatment of process of high concentration and refractory organic wastewater.
Background technology
High concentration and refractory organic wastewater is usually to be discharged by industries such as papermaking, leather, printing and dyeing and food, these industries
Production waste component is generally all more complicated, pollutant kind is various, usually have CODcr high, BOD5 high, SS concentration height,
The features such as NH3-N concentration is high, coloration is high.For example, a large amount of inorganic salts substance, such as carbon can be added in the production process of textile fabric
Sour sodium, sodium bicarbonate (sodium bicarbonate), sodium polyphosphate, salt (sodium chloride), anhydrous sodium sulphate (sodium sulphate), sodium hydrosulfite (dithionic acid
Sodium) etc., it is all transferred in waste water substantially after use, is the major pollutants of waste water.Such as without desalting processing, then salt in water
Amount of substance can be run up to quite greatly, influence the reuse of water.
Through research, when the conductivity of dyeing water is more than 3000uS/cm, i.e., when salt content is approximately more than 2000mg/L, salt holds
Mottling is easily generated on the fabric, influences the quality of product.Secondly, salt content is excessively high, and harmful effect is generated to wastewater biochemical processing,
Even sewage disposal system is made to collapse.Total salinity is 2000mg/L (always to dissolve in the Industrial Wastewater Treatment water outlet of not reuse
Property solid TDS indicate), reclamation rate 80%.The TDS of system will be added to 3400mg/L after circulation primary, will increase after secondary cycle
It is added to 4560mg/L, repeatedly after cycle, the TDS in recycle-water will cause production that can not be normally carried out.
Using processing such as conventional physico-chemical process, bioanalysis, although can reach country and local wastewater discharge standard (COD<
100mg/L, SS<60mg/L, pH6-9), but waste water still nonresident portion organic matter, microorganism, colloid, particle after processing is up to standard
Suspended matter and great amount of soluble inorganic salts etc., thus limit it and recycle, directly outer row causes water resource waste.
