Example Embodiment

[0037] Example 1:

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

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

[0040] The underwater trolley 1 includes a base 1a made of stainless steel plate. The base 1a is equipped with a driving device for driving the front and rear stroke of the underwater trolley, and the base 1a is equipped with a steering for realizing the left and right steering of the underwater trolley. The equipment has a bracket 1g on one side of the base 1a. The bracket 1g is equipped with an extraction pipe for sucking sewage and dirty oil. The suction port of the extraction pipe is set toward the water surface. The extraction pipe can be a hose Cargo bellows. The extraction pipeline is connected with a mud pump, the mu...

Example Embodiment

[0047] Example 2:

[0048] This embodiment provides a sewage oil separation and water purification method based on the above structure, which includes the following steps:

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

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

[0051] Step S3: Add the stirred inorganic flocculant to the dissolved air flotation machine through the first dosing tank, and stir in the first dosing tank for 15 minutes in advance;

[0052] Step S4: Add the stirred organic flocculant to the dissolved air flotation machine through the second dosing tank and stir in the second dosing tank for 30 minutes in advance;

[0053] Step S5: Stir the inorganic flocculant and organic flocculant evenly in the dissolved air flotation machine, separate the dirty oi...

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...
