Septic tank sewage odor-resistant discharge device for municipal environmental protection engineering

Abstract

The invention provides a septic tank sewage odor-resistant discharge device for municipal environmental protection engineering, and belongs to the field of septic tank. The septic tank sewage odor-resistant discharge device comprises a septic tank body, a sewage inlet pipe, a partial pressure deodorization discharge mechanism for discharging sewage and a biogas collection mechanism for collectingbiogas, wherein the partial pressure deodorization discharge mechanism is located below the septic tank body, the biogas collection mechanism is located above the septic tank body, and a first partition plate is fixedly connected to the inner wall of the septic tank body. According to the septic tank sewage odor-resistant discharge device for municipal environmental protection engineering, throughthe discharge mechanism, gas and sewage discharge of the whole septic tank is integrally communicated; pressure dynamic balance is kept between gas and liquid; gas leakage can be avoided, discharge pressure can be relieved, and therefore the problems that a common septic tank discharge device bears large pressure, a large amount of biogas dissolved in sewage easily occupies the conveying space and even causes pipeline leakage, and the septic tank and a pipeline are prone to biogas leakage to pollute soil and air are effectively solved.

Description

technical field [0001] The invention relates to the technical field of septic tanks, in particular to a deodorizing discharge device for septic tank sewage used in municipal environmental protection projects. Background technique [0002] The septic tank is a device for treating feces and filtering sediment. The solidified matter decomposes at the bottom of the pool, and the hydrated objects on the upper layer flow into the pipeline. Since the septic tank will generate a huge amount of methane during the sedimentation reaction, even in the pipeline When transporting the settled sewage, there will still be a large amount of biogas that will be integrated into the water and flow away. During the process of transporting the sewage full of vitality, the flow of sewage will generate a large amount of biogas. These gases are difficult to release, and the breakthrough is often found at the joints of the pipelines. When vented, a pungent smell can often be smelled near the sewage pi...
