Problems solved by technology

However, when the wastewater contains volatile organic compounds, harmful gases will enter the air with aeration, resulting in secondary pollution; on the other hand, the microorganisms attached to the filter material will also produce ammonia nitrogen, hydrogen sulfide and other harmful gas
Due to the odor caused by the escaping gas, the use of traditional biofilters in residential areas is limited
In order to remove the odor generated during the operation of the biofilter, the main measures currently taken are to seal the biofilter, and then introduce all the generated gas into an odor treatment device through an air pump, which consumes power Larger, and due to the suction effect, the rise rate of dissolved oxygen at the bottom of the biofilter is accelerated, and the utilization rate of oxygen is reduced

Abstract

The invention discloses a quasi-ecological biologic filtration pool capable of purifying escaping gas, comprising a biologic filtration pool and a gas processing device, wherein the gas processing device comprises a casing, a porous connecting plate, a flow diversion bottom plate and a flow diversion plate, the porous connecting plate is positioned at the lower side of the casing, and a plurality of connecting plate hole openings are arranged on the porous connecting plate; the upper side of the casing is provided with an air vent, both the flow diversion bottom plate and the flow diversion plate are arranged in the casing, the flow diversion bottom plate is positioned at the bottom, the inside of the casing forms at least two layers of space structures by the flow diversion plate horizontally arranged, and a filler is arranged on the flow diversion plate; and the gas processing device is communicated with the biologic filtration pool by the connecting plate hole openings. The invention integrates source collection, in situ processing and an integral reactor, adopts the stereo installation of sewage treatment and stench treatment, can be widely applied to the deep treatment and reclamation of sewage in a residential area and has the advantages of simple installation, easy acquirement of the filler, convenient replacement of the filler, good treatment effect, and the like.

Description

technical field [0001] The invention relates to a quasi-ecological biological filter capable of purifying escaped gas, belonging to the technical field of sewage treatment. Background technique [0002] At present, biofilters have been widely used in the advanced treatment and reuse of domestic sewage. The biofilters in the prior art are generally composed of filter beds, aeration systems, pulse backwashing sludge discharge systems, water distribution and effluent collection systems. , high degree of automation and easy maintenance. However, when the wastewater contains volatile organic compounds, harmful gases will enter the air with aeration, resulting in secondary pollution; on the other hand, the microorganisms attached to the filter material will also produce ammonia nitrogen, hydrogen sulfide and other harmful gas. Due to the odor caused by the escaping gas, the use of traditional biofilters in residential areas is limited. In order to remove the odor generated duri...
