Embodiment 1

[0031] Example 1 Bioenhancer is applied to microbial treatment unit to treat m-dichlorobenzene sewage

[0032] Firstly, the concentrations of dichlorobenzene in the middle of seven different sewage ponds were measured to be 65mg / L, 78mg / L, 91mg / L, 104mg / L, 130mg / L, 156mg / L and 195mg / L. In this embodiment, the efficiency of microbial degradation of m-dichlorobenzene is improved by adding a biological enhancer to the microbial treatment unit. By component: rhamnolipid 150g / L, FeCl 3 5g / L, MgCl 2 2g / L, MnSO 4 ·H 2 O0.13g / L, ZnCl 2 0.23g / L, CuSO 4 ·H 2 O 0.03g / L, CoCl 2 ·6H 2 O 0.42g / L, Na 2 MoO 4 2H 2 O 0.15g / L, AlCl 3 ·6H 2 O 0.05g / L, the solvent is water to configure a liquid bio-enhancer. After calculation, the flow rate of the aerobic pool of the wastewater treatment facility is 1000L / h, and the addition rate of the biological enhancer through the spray device above the aerobic pool is 1L / h.

[0033] After the aerobic pool was running stably, samples were taken...

Embodiment 2

[0034] Example 2 Bioenhancer applied to the m-dichlorobenzene wastewater prepared by the microbial treatment laboratory

[0035] Method for preparing m-dichlorobenzene wastewater: adding KH to distilled water 2 PO 4 、Na 2 HPO 4 , (NH 4 ) 2 SO 4 , CaCl 2 Make the concentrations reach 0.5g / L, 0.5g / L, 2g / L, and 0.01g / L respectively. After sterilization, add m-dichlorobenzene at a concentration of 130mg / L. Inoculate m-dichlorobenzene dominant bacteria.

[0036] In this example, the efficiency of microbial degradation of m-dichlorobenzene is improved by adding a biological enhancer. By component: rhamnolipid 150g / L, FeCl 3 5g / L, MgCl 2 2g / L, MnSO 4 ·H 2 O 0.13g / L, ZnCl 2 0.23g / L, CuSO 4 ·H 2 O 0.03g / L, CoCl 2 ·6H 2 O 0.42g / L, Na 2 MoO 4 2H 2 O 0.15g / L, AlCl 3 ·6H 2 O 0.05g / L, the solvent is water to prepare the biological enhancer. Add according to the total volume of 0.1%, place at 30°C, 150r / min shaker culture, take samples every 12h, after determination, t...

Embodiment 3

[0037] Example 3 Bioenhancer is applied to the trickling filter tower facility to treat m-dichlorobenzene waste gas

[0038] The concentration of dichlorobenzene in the waste gas of 7 different trickling tower facilities was measured to be 1021mg / m 3 , 1134mg / m 3 , 1264mg / m 3 , 1064mg / m 3 , 1313mg / m 3 , 1357mg / m 3 and 1214mg / m 3 . In this embodiment, the efficiency of microbial degradation of m-dichlorobenzene is improved by adding a biological enhancer to the microbial treatment unit. By component: rhamnolipid 150g / L, FeCl 3 5g / L, MgCl 2 2g / L, MnSO 4 ·H 2 O 0.13g / L, ZnCl 2 0.23g / L, CuSO 4 ·H 2 O 0.03g / L, CoCl 2 ·6H 2 O 0.42g / L, Na 2 MoO 4 2H 2 O 0.15g / L, AlCl 3 ·6H 2 O 0.05g / L solvent is water to prepare biological enhancer. Add it into the circulating spraying device, and the addition ratio is 0.1%. After the dripping filter facility was running stably, samples were taken respectively, and the concentration of dichlorobenzene in the exhaust gas was dete...

Abstract

The invention discloses biological fortifier for improving efficiency of degrading m-dichlorobenzene by microorganism in the liquid phase and an adding method thereof. The biological fortifier is prepared from rhamnolipid, FeCl3, MgCl2, MnSO4.H2O, ZnCl2, CuSO4.H2O, CoCl2.6H2O, Na2MoSO4.2H2O and AlCl3.6H2O. The method for improving efficiency of degrading m-dichlorobenzene by the biological fortifier in the liquid phase includes the following steps that 1, the average flow rate of the liquid phase in waste water or waste gas in biological equipment is calculated, and the biological agent is added according to the ratio of 0.1%; the biological agent is uniformly added into the waste water or gas microbiological treatment in a spraying mode. The provided biological fortifier is scientific and reasonable in component matching, capable of greatly improving the efficiency of degrading m-dichlorobenzene by microorganism, low in cost and high in operability, has a great significance in environment protection and has important application value.

Description

technical field [0001] The invention relates to a biological enhancer, in particular to a biological enhancer which can improve the efficiency of microorganisms to degrade m-dichlorobenzene in a liquid phase and a method for using the enhancer to increase the efficiency of microorganisms to degrade m-dichlorobenzene in a liquid phase. Background technique [0002] With the continuous development of the national economy, the organic pollutants produced in various industries are also increasing. These pollutants enter the environment through water and air, and have an impact on the environment and human health. Due to the toxicity, volatility, and structural stability of organic pollutants, my country's emission standards for various organic pollutants are becoming more and more stringent. m-dichlorobenzene is not only an intermediate of pesticides, medicines, papermaking, and dyes, but also an important raw material and organic solvent for many organic synthesis. With the wi...
