Problems solved by technology

[0003] Commonly used biological trickling filter equipment can only be used for odor and simple organic waste gas treatment, but not for small flow sewage treatment in towns, villages, urban residential areas, medical institutions, small and medium-sized enterprises, and urban service industries
Conventional sewage treatment cannot be used for the treatment of odor and organic waste gas
[0004] In addition, conventional biochemical equipment uses ceramic Raschig rings, plastic Raschig rings and other fillers as fillers, which have the following defects: 1. The fillers are piled up in disorde

Embodiment example 1

[0036] Embodiment 1, the method for treating exhaust gas according to the present invention includes the following steps:

[0037]1) Close the valve 14 ′, and according to the properties of waste gas treatment, add circulating nutrient liquid and biological strains of different components into the reaction through the valve 14 . The strains can be taken from the activated sludge of urban domestic sewage treatment plants.

[0038] 2) Close the valve 14, circulate the circulating nutrient solution and biological strains in the reactor repeatedly through the circulating water pump 10, and evenly spray on the whole enzyme floating packing 7, 7', 7", and flow into the water collection area 12.

[0039] 3) The valve at the bottom of the water collection area 12 is opened to maintain the same flow rate as the circulating fluid outlet 9 . Finally, the circulating nutrient solution entrained with microorganisms flows into the sedimentation zone 8 and is repeatedly circulated through t...

Embodiment example 2

[0042] Implementation case two, the method for treating sewage of the present invention may further comprise the steps:

[0043] 1) Close the valve 14', open the valves 14, 14" and 14"', let the sewage and biological bacteria enter the spraying device 4 through the sewage inlet, and then close the valve 14".

[0044] 2) The mixture of sewage and biological strains is evenly sprayed onto the whole enzyme floating packing 7, 7', 7", and flows into the catchment area 12. The valve at the bottom of the catchment area 12 is properly opened according to the quality of the influent water.

[0045] 3) Fresh air enters the reactor tower body 1 through the exhaust gas inlet 3, and controls the amount of air inflow by adjusting 14". After 1 to 2 weeks of domestication and debugging, the whole enzyme floating packing 7, 7', 7" With a uniform biofilm attached, sewage can be effectively degraded.

[0046] 4) Open the valve 14 again to continuously flow in the sewage and open the valve 14' ...

Embodiment example 3

[0047] Implementation case three, the combined treatment method of sewage and waste gas of the present invention, comprises the following steps:

[0048] 1) Close the valve 14', open the valves 14, 14" and 14"', let the sewage and biological bacteria enter the sedimentation zone 8 through the sewage inlet, and then close the valve 14".

[0049] 2) Sewage and biological strains flow through the circulating fluid outlet 9, the circulating water pump 10, the circulating fluid inlet 5, and the spraying device 4, and are evenly sprayed onto the whole enzyme floating packing 7, 7', 7", and flow into the catchment area 12.

[0050] 3) The valve at the bottom of the catchment area 12 is moderately opened according to the quality of the influent water. If the influent NH 3 -N concentration is high, the opening degree is increased, and the denitrification rate is increased.

[0051] 4) Odor gas or low-concentration organic waste gas enters the reactor tower body 1 through the waste ga...

Abstract

The invention discloses a biochemical device for integrally treating exhaust gas and sewage. The biochemical device comprises a reactor tower body, an exhaust gas outlet, an exhaust gas inlet, a spraying device, a circulation liquid inlet, a manhole, structured enzymes floating filler, a settling zone, a circulation liquid outlet, a circulation water pump, a sewage inlet, a water collection zone, a water outlet and a valve. The filler is structured, the upper layer and the lower layer are arranged and installed in a crossed mode, liquid is secondarily and uniformly distributed in the downstream process, and due to the fact that the novel enzyme floating filler is very good in a hydrophilia and adsorbs zoogloea in muddy water very easily, sludge grows easily; due to the fact that intervals among the structured filler are uniform, no large difference exists between gas resistance and liquid resistance, and when reaching a certain thickness, a filler biological film can naturally disengage, and a dynamic balance is reached; the filler blockage problem is eliminated.

Description

technical field [0001] The invention relates to the technical field of environmental protection biological treatment, in particular to a biochemical equipment for integrated treatment of waste gas and sewage and a treatment method thereof. Background technique [0002] Including garbage treatment plants, feces treatment stations, fine chemical production plants, sewage sludge treatment plants, petrochemical, paint plants and other enterprises that produce low concentrations of malodorous gases or low concentrations of volatile organic compounds. There are many treatment methods for odor, which are mainly divided into ion method, combustion method and absorption and adsorption method, among which the most economical and effective method is biological method. There are three main processes for biological treatment of waste gas: biological scrubbing, biological filtration and biological trickling, among which biological trickling is the most commonly used biological deodorizati...
