ABI-CASS SBR sewage treatment device and method consisting of a triple-type micro-nano bubble generation unit and a field intelligent control unit

摘要

The present invention discloses a conventional venturi tube type sludge decomposition type sewage treatment method, but the sludge is not crushed to a sufficiently small size by the venturi tube, so the sludge crushing efficiency is lowered, and the water treatment efficiency is lowered due to the decrease in the activity of microorganisms. , the entire water treatment process is centered on a uniform program rather than on-site. Bioreactor tank, secondary bioreactor tank, sludge storage, aeration pipe, decanter for discharge, triple-type micro-nano-bubble generator, underwater slide-type water quality detection sensor module, and on-site intelligent control unit are included. Due to the supply of micro-nano-sized oxygen from 10㎛ to 50㎛ from the direction to the bottom, and the sludge crushing of micro-nano bubble injection and bubble bursting, a large lump of sludge is crushed and divided into small pieces to feed the digestive microorganisms (substrate) By increasing the specific surface area of the sludge to be used, decomposition can be facilitated, and thus the activation rate of the microbial contact atmosphere can be improved by 80% compared to the existing ones, and after measuring the water quality in real time, the water quality Depending on the state, the operating time of each mode consisting of aeration/mixing mode (Fill-Aeration), micro/nano bubble injection mode, settling mode (Fill-Settle), discharge mode (Effluent Remova), and rest mode (Fill-Idle) and The purification and discharge cycle can be intelligently controlled 1:1 intelligently according to the water quality condition of the site, so that the treatment speed of wastewater can be increased by 1.5 to 3 times, and simultaneous nitrification and denitrification with phosphorus (P) removal It can be achieved, and the cultured microorganisms are transferred to the contact tank by controlling the supply and interruption of supply and supply of micro-nano-sized oxygen from the top to the bottom of the wastewater surface, and the control of the air supply and interruption of the air diffuser from the bottom to the top of the wastewater. When the wastewater treatment efficiency is improved by 80% by delaying or remarkably reducing the occurrence of factors impeding wastewater treatment by supplying it to the right place at the right time An object of the present invention is to provide an ABI-CASS SBR wastewater treatment apparatus and method comprising a triple-type micro-nano bubble generator and an intelligent on-site control unit that can be killed.
