Abstract

The invention discloses a sewage treatment apparatus for environmental engineering. The sewage treatment apparatus comprises a sludge outlet, a heavy metal recovery box, a centrifugal mud sucking pump, a sludge placing box, a sewage inlet, an electromagnetic control valve and a first-stage treatment box, wherein the sewage inlet is arranged above an operation control box, the electromagnetic control valve is arranged above the sewage inlet, the first-stage treatment box is arranged above the electromagnetic control valve, a second-stage treatment box is arranged below the first-stage treatmentbox, an oxygen manufacturing machine is installed below the second-stage treatment box, a third-stage treatment box is installed below the oxygen manufacturing machine, a purified water outlet is installed below the third-stage treatment box, and a sludge outlet valve is installed below the purified water outlet. The sewage treatment apparatus of the present invention can effectively treat sewagecontaining oil stains and silt, and further has characteristics of high filtration flow rate, high degreasing efficiency and high filtration precision.

Description

technical field [0001] The invention relates to the field of sewage treatment equipment, in particular to a sewage treatment device for environmental engineering. Background technique [0002] Environmental engineering is a branch of environmental science. It mainly studies how to protect and rationally utilize natural resources, use scientific means to solve increasingly serious environmental problems, improve environmental quality, and promote environmental protection and social development. It is a science and technology that studies and engages in the prevention and control of environmental pollution and the improvement of environmental quality. Environmental engineering is related to ecology in biology, environmental hygiene and environmental medicine in medicine, and environmental physics and environmental chemistry. Since the Environmental Engineering Department is in its initial stage, the field of discipline is still developing, but its core is the control of envir...
