MICRO BUBBLE DIFFUSER FOR TREATMENT OF WASTEWATER

摘要

A micro bubble diffuser for wastewater treatment is provided to improve efficiency of dissolved oxygen by supplying the oxygen with low cost smoothly, and to perform a dissolving, a denitrification and a dephosphorization processes of ammonia gas materials effectively. A micro bubble diffuser for wastewater treatment includes a micro bubble generating unit(100) and a gas-liquid amplification spreader(102). The micro bubble generating unit includes a head(104) and a baffle part(106). The heat is connected with an air supply pipe(110) and a waste inlet(108). The baffle part makes micro bubbles by mixing the air and waste water with the head. The gas-liquid amplification spreader comprises a housing(126) and a gas-liquid amplification spreading unit(130). The housing has a cylindrical pipe shape, and connected with the bottom of the micro bubble generating unit. The gas-liquid amplification spreading unit is inserted into the housing, and a plurality of pin-fins(132) are formed on an outer circumference of the gas-liquid amplification spreading unit.
