Technical field
The present invention relates to waste water treatment field, particularly relate to a kind of high salinity process for treating industrial waste water based on biological chemistry processing.
Background technology
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
-,
na
+, Ca
2+and difficult degradation or poisonous organism, and its quantity discharged is the trend of sharp increase.Therefore, explore effective organic high-salinity wastewater treatment technology and become one of focus of current wastewater treatment.
The treatment process of tradition high salinity trade effluent adopts physico-chemical process processing, and investment is large, and working cost is high, and is difficult to reach the decontamination effect improving of expection.In addition, existing treatment process adopts single treatment process to carry out purification of waste water processing conventionally, and processing efficiency is low and decontamination effect improving is undesirable, cannot thoroughly solve waste water pollution problem.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of novel high salinity process for treating industrial waste water based on biological chemistry processing is provided, physico-chemical processes and biochemical process are combined to improvement high salinity trade effluent, through three grades of desalting treatment, effectively remove the salinity in waste water.
The object of the invention is to be achieved through the following technical solutions: the high salinity process for treating industrial waste water based on biological chemistry processing, it comprises the following steps:
S1: high salinity trade effluent is imported to immersion ultrafiltration system, the colloid in filtered wastewater and particulate matter;
S2: the waste water after uf processing is imported to electrodialysis system, waste water is carried out to single stage desalting;
S3: the fresh water that produces through electrodialysis process is regulated to PH to 6.2～6.5, then import reverse osmosis system and carry out secondary desalination;
S4: the waste water after secondary desalination is imported to bio-contact oxidation system, waste water is carried out to three grades of desalinations, remove the COD in waste water;
S5: will import second pond through bio-contact oxidation waste water after treatment and precipitate.
Described bio-contact oxidation system adopts pure oxygen aeration and two sections of biochemical modes of bio-contact oxidation.
The invention has the beneficial effects as follows:
1) waste water is after immersion ultrafiltration, electrodialysis and reverse-osmosis treated, then through bio-contact oxidation processing, and physico-chemical processes and biochemical process are combined and administer high salinity trade effluent, through three grades of desalting treatment, effectively removed the salinity in waste water;
2) treatment scheme of the present invention is simple, and occupation area of equipment is little, and capital construction and working cost are lower and safe, efficient;
3) immersion uf processing can effectively be removed colloid and the particulate matter in waste water, makes the total suspended solid of waste water controlled, effectively reduces the Pollution risk of subsequent disposal;
4) purification efficiency is high, respond well, COD be 2370mg/L, the saltiness waste water that is 1.2%～1.7% after the present invention processes, water outlet BOD
5be less than 30mg/L, COD is less than 100mg/L, and COD clearance reaches 96%.
