High concentration organic wastewater using UASB pretreatment and then enter the total adjustment pool, mixed with low concentrations of organic wastewater, re-entering the main treatment system. Can be seen from the data, the high concentration organic wastewater using anaerobic treatment in UASB reactor for processing, the effect is good, CODcr, BOD and SS removal efficiency higher, so it not only for pharmaceutical wastewater treatment, can also be used soy products such as high concentration organic wastewater treatment. Data reported in the waste water treatment, high strength wastewater using UASB reactor pretreatment of mixed waste water into the AS (activated sludge) treatment (known as the UASB + AS method) and all directly into the AS method processing, the UASB + AS save aeration electricity than the AS method 68%, saving 59% of the sludge handling charges, biogas can also use; compared with the SBR process, operating costs, and sludge handling charges are lower than the SBR.
Food waste water treatment process
The food industry a wide range of raw materials, a wide range of products, the discharge of wastewater quantity and quality vary widely.
Major pollutants in wastewater
(1) floating solid matter in wastewater, such as leaves, peel, minced meat, poultry feathers
(2) of the material suspended in the wastewater, grease, protein, starch, colloidal substances
(3) dissolved in waste water, acid, alkali, salt, sugar, etc.
(4) raw material entrained sediment and other organic matter (5) deadly germs
The food industry wastewater is characterized by high content of organic matter and suspended solids, perishable, usually without major toxicity. The harm to the eutrophication of water bodies, resulting in the death of aquatic animals and fish, to promote underwater deposition of organic matter to produce odor, deteriorating water quality, pollution of the environment.
Food industrial wastewater treatment in addition to water quality characteristics of the appropriate treatment, in general, should be used for biological treatment. Demanding such as water quality or high organic content in wastewater, can be two aeration tank or two biofilter, or rotating biological contactors, or in combination of two biological treatment plant, may also have anaerobic an aerobic series of biological treatment systems. http://www.chuangxinhuayi.net
