Abstract
The present invention relates to the processing method of the higher fatty acid waste water of a kind of food industry, it comprises the following steps: A, waste water pump into anoxic baffled reactor and processes after flowing through multiple grid, enter anaerobism Aeration tank again and carry out anaerobic treatment, B, enter coagulating basin and carry out coagulating treatment, regulate pH to 7.5 8.5, first solid-liquid separation, dissolved air flotation again, C, it is combined after supercritical water oxidation processes through ultrasound wave, utilizes activated carbon to filter, then settlement treatment；D, first ensuring public security filtration, then micro-filtrate membrane filtration, then ultrafiltration membrance filter, last anti-seepage membrane filters, and i.e. obtains meeting the discharge water of environmental protection standard；Compared with prior art, the inventive method both can effectively decomposing food industry higher fatty acid waste water in Organic substance, reduce it acid, can effectively remove again the float such as COD, oils and fats, metal-oxide, colloid, antibacterial etc., not only can process waste water economical, efficiently, in a large number, simple to operate, operating cost is low, saves floor space, and obvious processing effect.
Description
Technical field
The present invention relates to chemical field, particularly relate to the processing method of a kind of industrial wastewater.
Background technology
In recent years, along with industry discharges such as the fast development of China's industry, some chemical industry, pharmacy, papermaking, food, fermentations
Substantial amounts of high solubility sulfate-containing organic wastewater is in natural, ecological water body.In water body, the sulfate of excess is possible not only to make water body
Smelly, water quality degenerates, and can strongly limit the growth of aquatile and plant, causes the salination of Soil Surrounding, in a word
What its water body caused, soil pollution were just becoming be on the rise and causes the extensive concern of people.
Industrial wastewater refers to waste water, sewage and the waste liquid produced in industrial processes, wherein contains the work outflowed with water
Industry produces the pollutant produced in materials, intermediate product and product and production process.Along with developing rapidly of industry, waste water
Kind and quantity rapidly increase, and the pollution to water body is the most extensive and serious, threatens the health and safety of the mankind.
Industrial wastewater generally has following three kinds of classification:
The first is by the chemical property classification of major pollutants contained in industrial wastewater, is main to be containing inorganic pollution
Inorganic wastewater, is main for organic wastewater containing organic pollution.Such as electroplating wastewater and the waste water of the mineral course of processing, be inorganic
Waste water；Food or the waste water of petroleum refining process, be organic wastewater.
The second is the product by industrial undertaking and processing object classification, as Metallurgical Waste Water, paper waste, coke-oven gas give up
Water, pickling of metal waste water, chemical fertilizer waste water, textile printing and dyeing wastewater, waste water from dyestuff, leather-making waste water, agricultural chemicals waste water, power station waste water
Deng.
The third is the main component classification by pollutant contained in waste water, such as acid waste water, alkaline waste water, gives up containing cyanogen
Water, chromate waste water, cadmium wastewater, mercury-containing waste water, phenol wastewater, aldehyde-containing sewage, oily waste water, sulfur-containing waste water, containing organophosphor give up
Water and radioactive wastewater etc..
First two classification method is not related in waste water the main component of contained pollutant, can not show the hazardness of waste water.
The third classification method, it is manifestly intended that the composition of major pollutants in waste water, can be shown that the hazardness that waste water is certain.The most also have
Major pollutants in waste water are summarized as three classes: the first kind is useless by the difficulty processed from waste water and the hazardness of waste water
Heat, essentially from cooling water, cooling water can be with reuse；Equations of The Second Kind is Conventional pollution, i.e. without overt toxicity and be prone to biological
The material of degraded, including biodegradable Organic substance, can be as the compound of biological nutrient, and suspended solid etc.；The
Three classes are toxic pollutant, i.e. containing the toxic and don't material of easily biological-degradable, including heavy metal, toxic compounds be difficult to
The organic compound etc. being biodegradable.
Existing food industry process for treating industrial waste water and system can not a large amount of process chemical industry discharges economic, effective
Sewage.
Summary of the invention
The technical problem to be solved be to provide a kind of can economical, efficiently, a large amount of process food industry discharges
The processing method of the higher fatty acid waste water of food industry of acid organic sewage and high treating effect.
The technical scheme is that
A kind of processing method of the higher fatty acid waste water of food industry, it comprises the following steps:
A, initial filter and anaerobic treatment
First higher fatty acid for food industry waste water is flowed through multiple grid, is then pumped into anoxic baffled reactor and reacts,
To remove oil slick organic acid is resolved into methane and carbon dioxide, then enter anaerobism Aeration tank and carry out anaerobic treatment, further
Remove the COD in waste water, i.e. obtain the waste water after anaerobic treatment；
B, coagulation and dissolved air flotation
Waste water after anaerobic treatment described in step A is entered coagulating basin, under agitation first feeding lime, then add
Enter coagulant and carry out coagulating treatment, then regulation pH to 7.5-8.5, then carry out solid-liquid separation, finally enter flotation tank and carry out gas
Floating separation, by oil removal by air bubbling dephosphorization, and removes oil removal further, i.e. obtains the waste water after air supporting；
C, oxidation processes filter with activated carbon
Waste water after air supporting described in step B is carried out ultrasound wave and is combined supercritical water oxidation process, then use work
Property charcoal filtering technique carries out filtration treatment, then carries out settlement treatment, the industrial wastewater after i.e. being filtered；
D, membrane filtration
Industrial wastewater after filtration described in step C first uses security personnel's filtering technique carry out filtration treatment, then adopts
Carry out filtration treatment by micro-filtrate membrane filtration technique, then use ultrafiltration membrance filter technique to carry out filtration treatment, finally use anti-seepage membrane
