Problems solved by technology

[0002] Organic industrial wastewater usually contains high-concentration, difficult-to-biodegrade, high-salinity, and highly toxic pollutants. Generally, there will be a certain period of debugging before the official operation of the sewage treatment system, so that the microorganisms in the water can adapt to the new environment and reproduce. This is inevitable The following disadvantages are brought about: the start-up period of the anaerobic system is long, the load increase is very slow, and the cultivation and acclimation time is usually 2-6 months, which limits the efficiency of anaerobic biological treatment
At the same time, the anaerobic biochemical process is susceptible to fluctuations due to external factors, and its recovery performance is poor, resulting in unstable anaerobic biological treatment effects

Embodiment 1

[0018] Nutrients for organosilicon wastewater treatment, the formulation of which contains the following components per liter of water: NH 4 HCO 3 30g, KH 2 PO 4 10g, FeSO 4 ·7H 2 O 2g, MnSO 4 ·H 2 O 0.5g, Al 2 (SO 4 ) 3 18H 2 O 0.5g, NiSO 4 ·6H 2 O 0.2g, CoSO 4 ·7H 2 O 0.05g, (NH 4 )6Mo 7 o 24 4H 2 O 0.05g, H 3 BO 3 0.05g. Weigh each component according to the mass ratio in the formula, add water and stir to dissolve each component, and then use 0.5mol / L H 2 SO 4 Adjust pH to 2. When in use, add the prepared nutrient to the organic silicon wastewater, mix well and then enter the anaerobic treatment system. The dosing ratio is 0.4L of nutrient per cubic meter of wastewater.

Embodiment 2

[0020] Nutrients for organosilicon wastewater treatment, the formulation of which contains the following components per liter of water: NH 4 HCO 3 45g, KH 2 PO 4 15g, FeSO 4 ·7H 2 O 20g, MnSO 4 ·H 2 O 1g, Al 2 (SO 4 ) 3 18H 2 O 0.8g, NiSO 4 ·6H 2 O 0.8g, CoSO 4 ·7H 2 O 0.5g, (NH 4 )6Mo 7 o 24 4H 2 O 0.1g, H 3 BO 3 0.1g. Weigh each component according to the mass ratio in the formula, add water and stir to dissolve each component, and then use 0.5mol / L H 2 SO 4 Adjust pH to 1. When in use, add the prepared nutrient to the organic silicon wastewater, mix well and then enter the anaerobic treatment system. The dosing ratio is 0.8L of nutrient per cubic meter of wastewater.

Abstract

The invention relates to a microorganism nutritional agent, in particular to a nutritional agent for organic silicon wastewater treatment. The formula of the nutritional agent includes that each literof water comprises, by weight, 30-45g of NH4HCO3, 10-15g of KH2PO4, 2-20g of FeSO4*7H2O, 0.5-1g of MnSO4*H2O, 0.5-0.8g of Al2(SO4)3*18H2O, 0.2-0.8g of NiSO4*6H2O, 0.05-0.5g of CoSO4*7H2O, 0.01-0.1g of (NH4)6Mo7O24*4H2O and 0.01-0.1g of H3BO3. The nutritional agent is rich in microorganism population, high in activity, good in anaerobic sludge granulation effect and high in anaerobic treatment efficiency, load impact resistance and COD (chemical oxygen demand) and benzene substance removal rate.
