Embodiment 1

[0038] The waste oil separation and water purification device has the advantages of high efficiency in extracting waste oil and high efficiency in water purification, such as figure 1 , figure 2 As shown, specifically set to the following structure:

[0039] Including underwater car 1, dosing system 2, sewage purification system 3.

[0040] The underwater car 1 includes a base 1a made of a stainless steel plate, the base 1a is equipped with driving equipment for driving the underwater car back and forth, and the base 1a is equipped with a steering wheel for realizing the left and right steering of the underwater car. The equipment has a support 1g on one side of the base 1a, and an extraction pipeline for sucking sewage and dirty oil is installed on the support 1g. The suction port of the extraction pipeline is set towards the water surface, and the extraction pipeline can be a water hose. Cargo bellows. The extraction pipeline is connected with a mud pump, the mud pump is...

Embodiment 2

[0048] This embodiment provides a method for separating dirty oil and purifying water based on the above structure, comprising the following steps:

[0049] Step S1: Place the underwater car on the bottom of the pool, and control the underwater car to walk on the bottom of the pool to reach the predetermined area;

[0050] Step S2: Start the mud pump to extract the waste oil through the extraction pipeline and pump it to the dissolved air flotation machine;

Abstract

The invention provides a dirty oil separation and purification device and method, relates to the technical field of sewage treatment, and aims to solve the problems of low dirty oil extraction efficiency and low sewage treatment efficiency. The dirty oil separation and purification device comprises an underwater trolley, a dosing system and a sewage purification system, wherein an extraction pipeline is mounted on the underwater trolley; the extraction pipeline is connected with a sludge pump; the sludge pump is connected with the sewage purification system through a sludge pipeline; the dosing system is connected with the sewage purification system through a dosing pipeline; and the suction hole of the extraction pipeline faces a water level. The underwater trolley is moved to an area with a high oil content and few sludge, sewage and dirty oil can be directly sucked into the sewage purification system for treatment, and the dirty oil extraction efficiency and the water purification efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage oil separation and water purification device and method. Background technique [0002] The treatment and disposal of sludge in sewage treatment plants should follow the principles of reduction, harmlessness, stabilization and resource utilization. With the rapid development of my country's economy and society, the pace of urbanization and industrialization is accelerating, the public's requirements for environmental quality are getting higher and higher, and the public's awareness of environmental protection is also increasing. Environmental protection and governance are the key to implementing the "five major development" concepts important work. According to the statistics of the Ministry of Housing and Urban-Rural Development, as of the end of September 2016, the number of sewage treatment plants in my country was 3,976, with a daily processing capacity of 17...
