AI Technical Summary

Technical Problem

When using the Fenton process to treat coal chemical wastewater in winter, the low ambient temperature leads to a prolonged reaction time, making it impossible to treat the wastewater transported from the upstream production system in a timely manner.

Method used

Wastewater treatment equipment is used to heat air via an electric heater and deliver it into the reaction tank, maintaining the oxygen content and temperature of the liquid layer inside the tank. Combined with temperature sensors and regulating valves, the reaction conditions are controlled to ensure that the Fenton reaction proceeds at a suitable temperature.

Benefits of technology

It shortens the Fenton reaction time, improves wastewater treatment efficiency, enables adaptive operation in different seasons, and enhances the equipment's working efficiency and economic benefits.

Abstract

This utility model relates to a wastewater treatment device, comprising a first buffer tank, several reaction tanks connected to the first buffer tank, a second buffer tank connected to the several reaction tanks, and several settling tanks connected to the second buffer tank. Each reaction tank is equipped with an aeration pipe and a first temperature sensor. An air supply main pipe is connected to the inlet end of each aeration pipe. A first air supply branch pipe is connected between each aeration pipe and the air supply main pipe. Each air supply branch pipe is equipped with a first regulating valve. The air supply main pipe is equipped with an air filter, a second temperature sensor, a blower, the inlet end of the second air supply branch pipe, a first shut-off valve, an electric heater, a third temperature sensor, a second shut-off valve, and the outlet end of the second air supply branch pipe. A third shut-off valve is also connected to the second air supply branch pipe. This device can compensate for the heat required by the Fenton reactor during winter operation. This utility model is easy to use and has broad market prospects.
