Description

A biological equipment removing an organic and inorganic bad-smelling material according to inflow load control means

The present invention is to control the inflow concentration of odorous substances generated in environmental foundations and industrial sites in real time to maintain the treatment efficiency by the microorganisms in the biofilter at all times to maintain a constant level and to reduce the operating cost biological organic And an apparatus for removing inorganic odorous substances.

In the case of odor occurrence, the amount of odor-causing substances emitted by seasonal factors and operating conditions varies. In winter, the temperature is low, the emission of odor-causing substances discharged into the atmosphere is low, and in summer, the temperature is high, so that the reaction of microorganisms and chemical reactions is promoted, and the amount of evaporation is also increased, thereby increasing the emission of odor-causing substances.

In addition, in the case of environment-based facilities, the occurrence of odor-causing substances is high when inflow of sewage or wastewater, and relatively low when there is no or little inflow.

In the case of existing odor prevention facilities, the throughput is determined by selecting the collection facilities and the ducts based on the maximum generation amount. In this case, since a certain amount is always processed regardless of the degree of odor generation, even if no odor is generated or a small amount is always processed, a consumption of energy, i.e., a cost is continuously generated.

In addition, since a certain amount of biofilters are always processed, the concentration of inflow is severe and direct impact is applied to microorganisms, so it is often difficult to maintain its activity. Provide supplementary facilities such as pretreatment facilities to supplement this. In the case of Korea Patent Publication No. 2002-0070182, it is a system that charges and removes the adsorbent in the biological treatment at the same time as the load fluctuation control means, and its effect depends on the lifetime of the adsorbent. the cost occurs.

As such, the existing prevention facilities are limited to biofilters and are fixed at the concentration and throughput of the inflowing gas, and thus economical and practical control means are lacking.

The present invention is to solve the above problems, the purpose of the present invention is to collect the odor-causing substances in real time and then transfer to the duct to remove the biological organic and inorganic odorous substances according to the inflow load control means treated by a biofilter It is to provide a device.
