Orange segment type micro-porous aeration system

Abstract

The invention discloses an orange segment type micro-porous aeration system, which comprises a reaction tank, an aeration main pipe, a plurality of aeration branch pipes and a plurality of aeration discs, wherein the aeration main pipe is fixedly arranged on the reaction tank; the aeration branch pipes are uniformly arranged on the aeration main pipe; the aeration discs are arranged on each aeration branch pipe; the pipe cavity of each aeration branch pipe is uniformly divided into a plurality of cavities by a partition plate to form a plurality of orange segment pipes of which the sectional shapes are similar to orange segments; and each aeration disc and the orange segment pipe are provided with corresponding serial numbers. According to the orange segment type micro-porous aeration system, the aeration discs can independently work without affecting mutually, and high reliability is guaranteed. As long as no more than three aeration discs on a single branch pipe are damaged, the entire system can normally operate and is maintenance-free; and the aeration of the aeration system is also extremely uniform and the aeration stability is extremely excellent. Each aeration disc and the orange segment pipe in the corresponding aeration branch pipe have corresponding serial numbers; and if one of the aeration discs is damaged, only one tailor-made air blockage sheet is required to be closely embedded in a corresponding through hole of a control valve without affecting the use of other aeration discs.

Description

Technical field: [0001] The invention relates to the technical field of sewage treatment, in particular to an orange petal microporous aeration system with easy maintenance and good aeration stability. Background technique: [0002] In the treatment of domestic sewage, industrial wastewater, and landfill leachate, in order to ensure the normal operation of the activated sludge in the biological pool, aeration is usually required to ensure sufficient oxygen supply. Microporous aerators (such as aeration tubes, aeration Pan, etc.) is a commonly used aeration equipment. Aeration equipment can save energy and make the oxygen transfer rate better, the air bubbles are evenly distributed, forming a uniform and gentle stirring state, and will not break the biological flocs due to excessive shearing, which is beneficial to the sedimentation of the secondary sedimentation tank and the sludge. Dehydration can also avoid various problems such as freezing and inconvenient management cau...

AI Technical Summary

Problems solved by technology

Although this microporous aeration system process mode has the above-mentioned advantages, it is an integrated control, which has problems such as inconvenient maintenance and poor aeration stability.

Taking the aeration pan as an example, assuming that the air velocity in the branch pipe is v=10-15m / s, the number of serving aeration pans is about 170, if 3 to 6 of the aeration pans are broken, in the aeration state Under normal conditions, the air volume will be extremely uneven, and most of the air will flow out from the damaged 3 to 6 aeration pans; in the state of no aeration, sewage will enter the damaged aeration pan, corrode the pipes, and even damage other aeration pans. Aeration disc

In addition, maintenance is inconvenient, and the entire aeration system needs to be stopped before maintenance can be performed, which greatly reduces the production capacity of the entire process and greatly increases its maintenance cost
