Waterpurifler tank that highten aerotropism the microbial sticking amount and force of survival that use net style overhang contact ashes.

摘要

The present invention relates to a septic tank that increases the adhesion amount and viability of aerobic microorganisms using a reticulated suspension contact material, and has a high flow rate with a sedimentation tank and a flow control function by blocking a plurality of diaphragms inside the body. The final settling tank including the adjusting column, the first contact aeration tank, the second contact aeration tank, the third contact aeration tank and the filtration tank is formed, and the compressed air supply pipe connecting the air ejection pipe installed in the final settling tank is installed long to the flow regulating tank. A vertical pipe is connected in the middle of the compressed air supply pipe located in the flow regulating tank, the first contact aeration tank, the second contact aeration tank, and the third contact aeration tank, and the diffuser is connected at the lower end of the vertical pipe to equalize the sewage concentration in the flow adjustment tank. And raise the sewage dissolved oxygen to increase the activation of microorganisms, and suspending hangers inside the first contact aeration tank, the second contact aeration tank and the third contact aeration tank. By installing a hanging rod and installing the contact medium of microbial contact media in each of the hanging hanger units in a vertical direction and horizontally, the aerobic microorganisms are increased, and the flow rate of sewage flowing in the body 10 is lowered. By extending the decomposition time of organic matter, the wastewater purification efficiency is very high.
