Embodiment 1

[0022] A rapid treatment method for oily sewage in ports (wherein the oily sewage is seawater), comprising the following steps.

[0023] Step 1. Sewage collection: Use a pump to transport the oily sewage to the emergency sump. After the sewage in the emergency sump is stabilized and stratified, use the oil pump to remove the upper oil phase. The equipment and procedures used in this step are prior art and belong to the known category, so they will not be repeated here.

[0024] Step 2, adsorption of oil-absorbing felt: spread the oil-absorbing felt on the treated sewage water surface in step 1, and use the oil-absorbing felt to absorb the oil in the sewage. The oil-absorbing felt is a polypropylene fiber oil-absorbing felt.

[0025] Step 3, oil-water separation: the sewage treated in step 2 is passed into an oil-water separator for oil-water separation.

[0026] Step 4, air flotation degreasing: pump the sewage treated in step 3 to the air flotation device for air flotation t...

Embodiment 2

[0036] A rapid treatment method for oily sewage in ports (wherein the oily sewage is seawater), comprising the following steps:

[0037] Step 1. Sewage collection: Use a pump to transport the oily sewage to the emergency sump. After the sewage in the emergency sump is stabilized and stratified, use the oil pump to remove the upper oil phase.

[0038]Step 2, adsorption of oil-absorbing felt: spread the oil-absorbing felt on the treated sewage water surface in step 1, and use the oil-absorbing felt to absorb the oil in the sewage. The oil-absorbing felt is a polypropylene fiber oil-absorbing felt.

[0039] The preparation steps of the polypropylene fiber oil-absorbing felt are as follows: dissolve 30 parts by weight of polypropylene in 300 parts by weight of tetrahydrofuran, stir at 60°C for 8 hours to obtain a polypropylene solution; dissolve 25 parts by weight of polymethyl methacrylate Dissolve in 300 parts by weight of dimethylacetamide, stir at 50°C for 2 hours to obtain a ...

Abstract

The invention discloses a method for rapidly treating oily sewage in a port. Oily sewage in the port is sequentially subjected to nine procedures including sewage collection, adsorption by an oil absorbent felt, oil-water separation, air-floating oil removal, ultrasonic oxidation, flocculation reaction, adsorption reaction, filtering for impurity removal and sterilization treatment, so that the oily sewage in the port can be rapidly treated, the removal efficiency is high, the effluent quality is stable, pollutants are basically removed, and the requirements for recycled water can be met. The method has remarkable time efficiency, can rapidly treat polluted water, and avoids the expansion of pollution range of oil.

Description

technical field [0001] The invention belongs to the field of port water pollution treatment, in particular to a rapid treatment method for port oily sewage. Background technique [0002] At present, the world's major trade transportation is completed by various seaports. When bulk commodities such as oil are in transit in the port, sometimes there will be sudden spills, which will lead to water pollution in the port. Oily sewage in ports has triple hazards of poisoning, environmental pollution and invasion of alien organisms. [0003] The above problems have attracted great attention from the government. Due to the promotion of environmental protection emergency plans and the implementation of the International Ocean Convention, people are eager to have emergency treatment, deep purification and reuse, and the elimination of foreign organisms on the premise of retaining and upgrading the existing biochemical system. Invasion and other three functions, and the cost and oper...
