[0015] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict. The following describes a shock-resistant odor biological deodorization treatment system provided by some embodiments of the utility model in combination with the accompanying drawings.
[0016] Example:
[0017] Combination Figure 1 As shown, the utility model provides an impact-resistant odor biological deodorization treatment system, comprising an anaerobic tank (1), an arched gas collecting hood (2) arranged above the anaerobic tank (1), the anaerobic tank (1) and the arched gas collecting hood (2) are connected to a gas collecting branch pipe (4), the gas collecting branch pipe (4) is connected to a gas collecting main pipe (5), a demister (7) installed on the vertical gas collecting main pipe (5) through a gradually widening pipe section (6) is arranged at the rear end of the centrifugal fan (3), a return pipe (8) is connected to the anaerobic tank (1), a biological deodorization spraying area (9) is connected to a biological treatment area (10), and a pH meter (11) and a salinity meter (13) are arranged in the spray water tank.
[0018] Specifically, pollutants such as hydrogen sulfide in the odor will change the pH of the spray water after dissolving in water. To prevent the acidity and alkalinity of the spray water from affecting the bacterial strains in the rear biological treatment area (10), when the pH meter (11) installed in the spray water tank detects that the pH of the spray water is acidic, an alkaline agent is added through the alkaline dosing device (12) to adjust the pH of the spray water to neutral; to prevent the spray water from being too saline due to continuous acid-base adjustment during operation, which affects the bacterial strains in the rear biological treatment area (10). When the salinity meter (13) installed in the spray water tank detects that the salinity is too high, the electric drain valve (14) is opened to discharge the spray water with too high salinity and replenish the spray water.
[0019] Working principle and use process of this utility model: The core design of the impact-resistant odor biological deodorization treatment system described in this utility model patent is to effectively deal with the situation where the anaerobic tank is unstable and produces a lot of foam due to the influence of temperature or influent water quality. Through a series of equipment and processing steps, the system can efficiently and stably remove pollutants in the odor to ensure that the final discharged gas meets environmental protection standards.
[0020] When a large amount of foam is generated in the anaerobic tank (1) due to the influence of temperature or influent water quality, the elevated arched air collecting hood (2) arranged above the tank body can effectively prevent the foam from being sucked into the centrifugal fan (3) and entering the air collecting main pipe (5) along with the odor.
[0021] The centrifugal fan (3) transports the odor to the demister (7) at the rear end through the gas collecting branch pipe (4) and the gas collecting main pipe (5). The demister (7) is installed on the vertical gas collecting main pipe (5) through a gradually widening pipe section (6), and can effectively remove foam in the odor. The foam on the demister (7) forms water droplets after condensation, and flows back to the anaerobic tank (1) through the return pipe (8), thereby realizing resource recycling.
[0022] The odor after defoaming first enters the biological deodorization spray area (9), and the spray water separates the water-soluble pollutants in the odor, such as hydrogen sulfide. The pH meter (11) in the spray water tank monitors the pH of the spray water in real time. When the pH is acidic, an alkaline agent is added through the alkaline dosing device (12) to adjust the pH of the spray water to neutral, so as to ensure the activity of the bacteria in the back-end biological treatment area (10).
[0023] In order to prevent the spray water tank from continuously adjusting the acidity and alkali during operation, which may cause the salinity of the spray water to be too high and affect the bacteria in the rear biological treatment area (10), the salinity meter (13) monitors the salinity of the spray water in real time. When the salinity is too high, the electric drain valve (14) automatically opens to discharge the spray water with too high salinity and replenish fresh spray water.
[0024] The odor after spraying treatment enters the biological treatment area (10) for deep biological deodorization. The microorganisms in the biological treatment area (10) can further decompose the organic pollutants in the odor to ensure that the final discharged gas meets the environmental protection standards.
[0025] The treated gas is discharged into the atmosphere through an exhaust pipe (15), thus meeting environmental protection requirements.
[0026] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
