Problems solved by technology

The traditional activated sludge method is difficult to adapt to the water quality characteristics of petrochemical wastewater at the present stage. Many oilfields at home and abroad have begun to use microbial methods to treat oilfield sewage, which has brought good economic benefits to the oilfield.

Abstract

The invention discloses a microorganism nutrient agent for sewage treatment. The nutrient agent is prepared from the following raw materials in percentage by mass: 15-70% of potato powder, 10-20% of cane sugar, 5-40% of cellulose, 0.5-2% of monopotassium phosphate, 0.5-2% of sodium ammonium, 0.5-3% of ammonium sulfate, 0.5-2% of magnesium sulfate heptahydrate, 0.5-2% of magnesium nitrate, 0.5-2% of calcium chloride, 0.5-4% of ferrous sulfate, 2-15% of peptone and 0.5-8% of oleic acid. As starch and cellulose are taken as main components and are combined with a great amount of organic and inorganic elements, the microorganism nutrient agent can be used for acclimating microorganisms in living wastewater and petrochemical wastewater and used for adjusting microorganism death caused by various insufficient nutrition components or ratio disorder, and has the advantages of being low in price, easy to obtain, free of pollution and rich in nutrition component.

Description

technical field [0001] The invention relates to the application technical field of cultivating and domesticating microorganisms for sewage treatment, in particular to a microbial nutrient for sewage treatment. Background technique [0002] In the oilfield wastewater treatment process, petroleum and suspended solids are generally treated by the method of oil separation-coagulation-filtration, but this method will make it difficult to meet the standards of some indicators of produced water, especially heavy oil sewage, polymer produced water, The CODcr of produced water with high salinity will be seriously high, and the compliance rate is only about 50%. Most other industries in China use biochemical treatment to solve the problem of high COD value, and the petroleum industry can also learn from this method. Using microbial methods to treat sewage can completely separate and decompose crude oil, which is not only low cost, easy to operate, and good degradation effect, but als...
