Embodiment Construction
[0027] The mode conversion of a one-column three-mode comprehensive treatment system with light bamboo charcoal as the filler of the present invention will be further explained below in conjunction with the drawings.
[0028] (1) In air mode, close the outlet valve 5 and inlet valve 6, and stop the circulating pump 8. Open the intake valve 2, the exhaust gas enters the tower through the fan 1 at a flow rate of 0.5-1m / s, passes through the bamboo charcoal packing 3 loaded with microbial membrane, and is adsorbed and degraded by the microorganisms on the packing. The purified gas is discharged through the outlet 4 to meet the standard. In this mode, the intake load of organic waste gas is 0-8.5g / (m 3 Filler h), the removal efficiency of VOCs is 90-99%, and the dust removal rate is 90-95%. Open the water outlet valve 5 and the water inlet valve 6 regularly, and use the circulating pump 8 to spray on the packing to maintain the packing humidity. If the filler is wet, close the water...

The invention provides a one-tower and tri-mode comprehensive treatment system which can co-treat waste gas and wastewater and randomly switch a gas mode, a water mode and a gas-water mode and takes bamboo charcoal as packing, and a method for treating the wastewater and the waste gas. The system comprises a treatment tower filled with bamboo charcoal packing loaded with a microorganism membrane, wherein an outlet of a fan is communicated with the bottom of the treatment tower through a gas inlet pipeline; an outlet of a circulating pump is communicated with a spraying system at the inner upper part of the treatment tower; the bottom of the treatment tower is communicated with a circulating water tank through a water outlet pipeline; the circulating water tank is communicated with an inlet of the circulating pump; the top of the treatment tower is communicated with a gas outlet. During treatment of the waste gas, the method adopts the gas mode; the waste gas enters the tower, passes through the bamboo charcoal packing loaded with the microorganism membrane, is adsorbed and degraded by microorganisms and then is discharged after meeting the standard; during treatment of the wastewater, the water mode is adopted; the wastewater is pumped by the circulating pump and then is sprayed by a spraying system; after passing through the bamboo charcoal packing and being adsorbed and degraded by the microorganisms, circulating treatment is carried out; furthermore, the wastewater and the waste gas are treated under the gas-water mode.
Description
Technical field [0001] The present invention relates to a device and method for treating waste water and waste gas. Specifically, it is a one-tower three-mode comprehensive treatment system with light bamboo charcoal as filler, and a method for treating waste water and waste gas using the light bamboo charcoal. Cooperative processing, air mode is used for waste gas treatment, water mode is used for waste water treatment, and air-water mode is used for waste water and waste gas treatment. These three modes can be switched at will. Background technique [0002] With the rapid development of the chemical industry, many chemical companies produce a large amount of organic waste gas and waste water in the production process, which seriously pollutes the human living environment. Chemical companies generally treat organic wastewater and waste gas separately. The separate organic wastewater and separate organic waste gas treatment processes cover a large area, high operating costs, and ...
