- the high sulfur content wastewater was treated by the apparatus of the present invention shown in FIG.
- the oxidizing agent is added to the water to be treated in the oxidation reaction tank 1 preceding the methane fermentation tank 2
- Fe, Ni, and Co are added, and the water is sent to the methane fermentation tank 2.
- the oxidation reaction tank 1 was not provided, and Fe and Ni-Co were added in the adjustment tank and then sent to the methane fermentation tank.
- the capacity of the reactor is 3 m3.
- the amount of generated gas collected in each gas phase section 6 was measured by a gas meter 8 provided in the water seal tank 3.
- the temperature of the water in the reactor 2 is controlled to be maintained at 35 ° C.
- a hydrogen sulfide concentration meter 10 was installed between the lowermost gas phase section 6 and the water sealing tank 3.
- the raw water contains wastewater mainly composed of methanol (COD cr: 700 to 1000 mg / L, dissolved sulfide: 100 to 6.00 mg / L) and inorganic nutrients such as nitrogen and phosphorus.
- wastewater mainly composed of methanol (COD cr: 700 to 1000 mg / L, dissolved sulfide: 100 to 6.00 mg / L) and inorganic nutrients such as nitrogen and phosphorus.
- COD cr 700 to 1000 mg / L
- dissolved sulfide 100 to 6.00 mg / L
- inorganic nutrients such as nitrogen and phosphorus.
- a part of the treated water was used as a circulating liquid and flowed into the reactor together with the raw water to set the water flow rate to 2 m / h.
- the ratio of raw water flow rate and treated water circulating water rate was set according to the COD load.
- FIG. 2 shows the progress of the experiment
- Figure 3 shows the change in the concentration of dissolved sulfide in raw water
- Figure 4 shows the concentration of hydrogen sulfide in the biogas
- Figure 5 shows the change in COD treatment results
- Figure 6 shows the change in the residual chlorine concentration.
- Comparative Example 1 when the dissolved sulfide concentration of the raw water was increased and the concentration of hydrogen sulfide in the biogas exceeded 4%, the COD cr removal rate decreased to about 10%. In Comparative Examples 2 and 3, the removal rate was low, almost no CODcr could be removed, and the removal rate was about 10%. A higher COD cr removal rate was obtained with the method of the present invention.

- U pflow An aerobic S ludge B lanket P rocess after referred to as "UA SB” U pflow An aerobic S ludge B lanket P rocess after referred to as "UA SB”
- U pflow An aerobic S ludge B lanket P rocess after referred to as "UA SB” This method Is characterized by the ability to granulate anaerobic bacteria such as methane bacteria into granules to maintain the concentration of methane bacteria in the reactor at a high level.As a result, the concentration of organic matter in wastewater is reduced. It can be processed efficiently even when it is considerably high.
- the oxidation is performed so that the concentration of hydrogen sulfide in the biogas generated in the anaerobic treatment step is 3% or less.
