AI Technical Summary

Technical Problem

Existing BDO wastewater treatment facilities fail to effectively treat sludge, leading to environmental pollution and resource waste. They also fail to collect and treat harmful gases inside, endangering human health and causing energy waste.

Method used

A BDO wastewater treatment device was designed, comprising an equalization tank, an aerobic biological treatment tank, a disinfection tank, an anaerobic digestion tank, a drying tank, and a gas collection system. The device uses a centrifugal pump to treat sludge, an electrochemical gas sensor to detect gas concentration, and an air intake to collect harmful gases, thereby achieving sludge stabilization and gas recovery and utilization.

Benefits of technology

It has achieved the harmless treatment and resource recycling of sludge, protected human health, reduced environmental pollution and energy waste, and improved wastewater treatment efficiency.

Abstract

This utility model relates to the field of wastewater treatment devices and discloses a BDO wastewater treatment device, including an equalization tank. An inlet pipe is fixedly connected to the top of the equalization tank, and a drain pipe is fixedly connected through and to the right side of the equalization tank. An aerobic biological treatment tank is fixedly connected to one side of the drain pipe. A disinfection tank is located on the right side of the aerobic biological treatment tank, and an outlet pipe is fixedly connected to the middle of the right side of the disinfection tank. In this utility model, sludge is sucked out through a sludge pipe, a centrifugal pump, an anaerobic digester, a drying box, a hot air pipe, and a hot air blower. The sludge is then fed into the anaerobic digester for reaction and degradation of organic matter, reducing COD and BOD. The sludge is then dried in the drying box by a hot air blower, achieving harmless treatment of the sludge and facilitating transportation. An electrochemical gas sensor, a gas suction machine, a gas storage tank, a gas suction head, and a controller are used to monitor and store toxic and harmful gas concentrations, ensuring personnel safety.
