1、 Advantages
Membrane microporous aerator is a new type of aerator developed in the 21st century. The aerator has small bubble diameter, large gas-liquid boundary area, uniform bubble diffusion, no pore blockage and strong corrosion resistance. It has been tested by the school of environmental engineering, Tongji University of Shanghai and the North China Design Institute of municipal engineering for oxygen charging of clean water and sewage, and has been used by more than 50 users for many years Fixed spiral aerator, diffused aerator and perforated pipe aerator can reduce energy consumption by 40%, or increase sewage treatment capacity by 40%). It is especially suitable for the construction and expansion of urban sewage and large-scale factories and the reconstruction of old aeration tank, and the aeration tank can operate intermittently.
2、 Connection and installation of aeration pipe
The aerator consists of aerator, gas distribution pipe, tee, cross, elbow, regulator, connector, cleaning device, etc. The air distribution pipeline is arranged in the usual ring, the aerator is arranged in the density according to the air supply volume and pool shape, the connection between the aerator and the air distribution pipeline is G3 / 4 thread, the base is internal thread (fixed on the air distribution pipeline) and the aerator is external thread. When installing, fix the regulator at the bottom of the pool with the expansion bolt according to the required size, and then fix the air distribution pipeline on the regulator with the hoop to prevent In other operations such as electric welding sparks and civil engineering, when concrete and other heavy objects damage the aerator, the aerator must be installed before water discharge after the completion of civil engineering. In order to prevent air leakage of pipeline and connecting part, the water shall be discharged to a depth of about 10cm above the bottom of the aerator for leakage test. If air leakage is found in the connecting part of the pipeline, it shall be removed in time and then put into operation formally.
