Problems solved by technology

[0002] Due to the characteristics of high organic matter content, kitchen wastewater is very easy to pollute the environment. Kitchen wastewater mainly contains starch, protein, oil and cellulose. The fermentation of these starch, protein, oil and cellulose is the main source of ammonia and hydrogen sulfide. The two main causes of odor, the existing equipment does not use bacteria for the degradation of ammonia and hydrogen sulfide, resulting in poor deodorization effect

Embodiment 1

[0038] Example 1: Please refer to figure 1 , figure 2 , Figure 4 , an environmental protection deodorization device for kitchen wastewater, including a deodorization tank 1, a microbial agent mixing unit 3 and a tank heating unit 26;

[0039] Deodorization tank 1: The top side of the deodorization tank 1 is inclined upward, and a feed channel 2 communicating with the interior is provided. The microbial agent mixing unit 3 is installed on the feeding channel 2, and the microbial agent mixing unit 3 contains microbial agents. The mixed bacterial agent for degrading starch, protein, grease and cellulose is contained in the putting box 34, and the mixed bacterial agent is dried Bacillus, Citrobacter and Lactobacillus, and the bottom of the feeding channel 2 passes through the support Rod 14 is connected to the bottom side of deodorizing tank 1, and the bottom of deodorizing tank 1 is supported by support frame 5, and support frame 5 is fixed on the base plate 21 by supporting ...

Embodiment 2

[0057] Example 2: Please refer to Figure 7 , the gas filter unit 24 includes an activated carbon filter plate 2421 and a fixed frame 2422, the diameter of the activated carbon filter plate 2421 is equal to the inner diameter of the ammonia gas absorption tank 16, and there are no less than two activated carbon filter plates 2421 fixed on the ammonia gas absorption tank by the fixed frame 2422 16 on the inner wall. This gas filter unit filters the air to be discharged through a multi-layer activated carbon filter plate, and the filtering effect is good, but correspondingly, the passing efficiency of the air to be filtered is slightly reduced.

[0058] In the actual experiment:

[0059] The following degradation rates adopt Chinese standards: GB / T19277 biodegradation rate standards and testing methods;

[0060] Fill a 180L vat with kitchen wastewater mainly containing starch, protein, oil and cellulose in a ratio of 4:3:1:1, using a ratio of 2:1:3 Bacillus, Citrobacter and La...

Abstract

The invention discloses an environment-friendly deodorization device and method for kitchen wastewater. The environment-friendly deodorization device comprises a deodorization tank, a microbial agentmixing unit and a tank body heating unit, a feeding channel communicating with the interior of the deodorization tank is obliquely arranged on the side face of the top of the deodorization tank upwards, the microbial agent mixing unit is installed on the feeding channel, and a mixed microbial agent used for degrading starch, protein, grease and cellulose is contained in a microbial agent containing box of the microbial agent mixing unit. The mixed microbial agent is prepared from dried bacillus, citrobacter and lactobacillus. Main components including starch, protein, grease and cellulose in the kitchen wastewater are degraded by using the mixed microbial agent of bacillus, citrobacter and lactobacillus. A mechanical temperature control module can effectively control a proper temperature,so that the mixed microbial agent is promoted to degrade two odors including ammonia gas and hydrogen sulfide at the same time at the proper temperature, and odor generation can be reduced, and odor can also be degraded.

Description

technical field [0001] The invention relates to the technical field of waste water environmental protection treatment, in particular to an environmental protection deodorization device and deodorization method for kitchen waste water. Background technique [0002] Due to the characteristics of high organic matter content, kitchen wastewater is very easy to pollute the environment. Kitchen wastewater mainly contains starch, protein, oil and cellulose. The fermentation of these starch, protein, oil and cellulose is the main source of ammonia and hydrogen sulfide. The main reasons for the two kinds of odor, the existing equipment does not use the fungus aimed at degrading ammonia and hydrogen sulfide, resulting in poor deodorization effect. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects, provide an environmental protection deodorization device and deodorization method for kitchen wastewater, a...
