Abstract
The invention discloses a high-salinity industrial wastewater treatment method based on biochemical treatment, which comprises the following steps: introducing high-salinity industrial wastewater into an immersed ultrafiltration system to filter colloid and particulate matters in wastewater; introducing into an electrodialysis system to primarily desalt the wastewater, regulating PH to 6.2-6.5 by using fresh water, and then introducing into a reverse osmosis system to secondarily desalt, and introducing into a bio-contact oxidation system to desalt the wastewater for the third time to remove COD (chemical oxygen demand) in the wastewater; and introducing the wastewater subjected to bio-contact oxidation treatment in a secondary sedimentation tank to precipitate. The high-salinity industrial wastewater is treated by combining a physical-chemical process and a biochemistry process after the immersed ultrafiltration, electrodialysis, reverse osmosis treatment and the bio-contact oxidization treatment; after three-level desalting treatment, the salt in the wastewater is effectively removed; the purifying efficiency is high, and the purifying effect is good; after the wastewater with the COD of 2370mg/L and the salt content of 1.2-1.7% is treated by the method disclosed by the invention, the effluent BOD5 (biochemical oxygen demand 5) is less than 30mg/L, the COD is less than 100mg/L, and the COD removal rate achieves 96%.

Organic high-salinity wastewater refers to the waste water containing the total dissolved solid thing (TDS) of organism and at least 3.5% (massfraction).This type of waste water mainly contains two sources: 1) seawater is directly used in the waste water discharging after industrial production and life, and as industrial, seawater can be widely used as boiler water coolant; In urban life, seawater can substitute fresh water as flushing water, and the saltiness of this type of waste water is generally 2.50 × 10
4～3.50 × 10
4mg/L (mass concentration); 2) waste water discharging in some industrial trade production process, as the waste water of saponin waste water, oil development waste water and printing and dyeing, papermaking, pharmacy, chemical industry, milk preparation processing and pesticide industry discharge, saltiness is generally in 15%～25% left and right.The environmental pollution that organic high-salinity wastewater is brought is very serious, and particularly saliferous trade effluent often contains the soluble inorganic salt Cl of high density
-,
