Abstract

The invention provides a multistage sewage treatment device and a sewage purification system and relates to the field of sewage purification. The multistage sewage treatment device comprises a device body, an oxygen supply device, a dissolved oxygen measurement device and a control system, wherein a sewage inlet and a purified water outlet is arranged on the device body; the device body further includes a settling section, a swirling oil-gas separation section, a large particulate matter filtration section, and a fine-particle filtration section which are sequentially arranged from top to bottom; the sewage inlet is arranged on the settling section and the purified water outlet is arranged on the fine-particle filtration section; the oxygen supply device is connected to the swirling oil-gas separation section through an oxygen supply pipe; the dissolved oxygen measurement device comprises a dissolved oxygen electrode which is arranged in the swirling oil-gas separation section and a dissolved oxygen meter which is electrically connected with the dissolved oxygen electrode and is arranged outside the device body; the dissolved oxygen meter and the oxygen supply device are electrically connected to the control system. The multi-stage sewage treatment device has the advantages that usage is simple, automation degree is high, sewage treatment effect is good, industrial production value is greater.

Description

technical field [0001] The invention relates to the field of sewage purification, in particular to a multi-stage sewage treatment device and a sewage purification system. Background technique [0002] With the rapid development of my country's economic construction, the problem of environmental pollution is becoming more and more serious, and the problem of water pollution has brought more and more serious impact on the environment. With the continuous development of China's oilfields, the average comprehensive water content of the produced fluid has exceeded 80%, the amount of sewage treatment continues to increase, and the types of sewage are complex and diverse, which puts forward higher requirements for sewage treatment technology and equipment. Whether sewage treatment meets the national environmental protection standards has become one of the important factors restricting the sustainable development of the petrochemical industry. [0003] However, the sewage treatment...
