Bottom-exposed micro-aerobic biological treatment machine for degrading cyclic compounds in coal pyrolysis wastewater

Abstract

The invention discloses a bottom-exposed micro-aerobic biological treatment machine for degrading cyclic compounds in coal pyrolysis wastewater. The structure of the micro-aerobic biological treatmentmachine comprises a side baffle frame, a double-air-duct bottom-exposed tank, a pressing buckle plate, a pool bottom plate, a fan box, a wastewater tank and a tank top cover plate. The cooperation between the double-air-duct bottom-exposed tank and the fan box is realized; a folded plate frame is matched with an inner air duct to form a gap pushing and pressing effect; carbon dioxide is continuously output through an exhaust wheel barrel groove; oxygen sustained supply sinks, when the cyclic compound in the coal pyrolysis wastewater is degraded, the autonomous oxidation aeration satisfactionrate of a micro-aerobic biological treatment system is improved; the operation effect is improved; the chain key hot air pressure decomposition operation of the wastewater cyclic compound is also improved, so that the internal circulation air pressure is matched with the aeration of an aeration disc bottom frame, the internal heat effect is also improved, the bottom aeration of the biologically filtered oxidation wastewater pool is efficient, the hot aeration biological area is wide, and the large-batch purification efficiency of the wastewater is improved.

Description

technical field [0001] The invention relates to a bottom-exposure micro-aerobic biological processor for degrading coal pyrolysis wastewater cyclic compounds, belonging to the field of biological filtration. Background technique [0002] The micro-aerobic biological treatment system uses the cultivation area of ​​biological filtration to promote the effect of wastewater filtration and purification, and also facilitates the biological oxidation and degradation of coal and pyrolysis wastewater cyclic compounds, so that the overall water source can be clarified and treated, ensuring the harmlessness of biological aeration and filtration The shortcomings of the current technology that need to be optimized are: [0003] Degradation of cyclic compounds in coal pyrolysis wastewater will produce carbon dioxide gas, which will have an inhibitory effect on the microaeric organisms at the bottom, resulting in a reduction in the area of ​​biological reproduction, and a large number of n...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a micro-aerobic biological processor for degrading coal pyrolysis wastewater cyclic compounds to solve the problem of carbon dioxide gas generated by degrading coal pyrolysis wastewater cyclic compounds. The micro-aerobic organisms at the bottom will produce an inhibitory effect, resulting in a reduction in the biological reproduction area, and the organisms are oppressed to survive without oxygen and necrosis, which affects the quality of water biological filtration, and the filtration area is small, resulting in the extrapolation of the incoming oxygen by a large amount of carbon dioxide accumulation. , resulting in low aeration quality of micro-aerobic organisms, insufficient oxidation degree, and the amount of carbon dioxide in the internal circulation is degraded by degradation of coal pyrolysis wastewater cyclic compounds still continue to increase, resulting in low efficiency of biological filtration in the pool
