Abstract
The invention discloses a novel composite demulsifier for environmental protection. The novel composite demulsifier comprises the following components in parts by weight: 10-15 parts of an initiating agent, 3-5 parts of a polymeric flocculation compound, 5-10 parts of sodium hydroxide, 10-15 parts of granular activated carbon, 5-10 parts of isobutanol, 3-5 parts of succinic acid, 8-15 parts of ethoxy polysilane and 3-5 parts of carboxymethyl cellulose. The invention provides the composite demulsifier and a preparation method thereof so as to overcome the defect that a conventional demulsifier is re-dissolved into water after demulsification.
Description
Technical field
The present invention relates to field of Environment Protection.It is more particularly related to a kind of NEW TYPE OF COMPOSITE demulsifier for environmental protection
And preparation method thereof.
Background technology
The mankind, animal and plant or even whole ecosystem are all exerted an adverse impact by oily waste water, and its harm is main
Show following two aspects:
1. the harm of pair enterprise.Waste water containing oil emulsion, can in process facility and pipe-line equipment with waste water in suspend
Grain and iron scale settle together, form normally entering of the greasy filth group with bigger stickiness, blocking pipeline and equipment impact production
OK.
2. the harm of pair environment.Oily substance is many on the impact of environment, such as polluted-water, is formed on the water surface
Oil film, can hinder water reoxygenation effect, reduces due to dissolved oxygen in water body, and algae photosynthesis is restricted, and affects aquatic life
The normal growth of thing, makes aquatic animals and plants have oily taste or toxicity, even makes water body foul, and destroys the value of water resource；Oil
Class is attached on the fish gill, and fish can be made to suffocate, and when concentration is 200mg/L, Fish can not survive；It is attached on algae, plankton,
Them can be made dead；Oils can suppress aquatic bird lay eggs and hatch, and makes birds mortality time serious；Agriculture is irrigated with oily waste water
Field, oil point and derivant thereof by mulching soil and the surface of plant, the hole of blocking soil, stop air to penetrate, make soil and
Microorganism can not be normally carried out metabolism, makes agricultural product quality and practical value decline, can cause crop production reduction time serious
Or dead, oils migrates downward in soil, it is also possible to cause serious underground water pollution.
Demulsifier mostly biases toward the simple process of breakdown of emulsion at present, and after result causes breakdown of emulsion, rear end can be redissolved in water,
Be not reaching to basic breakdown of emulsion purpose, so, market demand can demulsification good, and there is the compound of the purpose of elimination
Demulsifier.
Summary of the invention
It is an object of the invention to provide a kind of NEW TYPE OF COMPOSITE demulsifier for environmental protection and preparation method thereof, existing to overcome
The shortcoming that demulsifier exists " being re-dissolved in water after breakdown of emulsion ".
To achieve these goals, the technical solution used in the present invention is as follows:
A kind of NEW TYPE OF COMPOSITE demulsifier for environmental protection, including the component of following weight portion:

Preferably, the one during described initiator is selected from polyoxypropylene, polyoxyethylene or combination in any.
Preferably, during described polymerization flocculating compound is selected from aluminium polychlorid, polyaluminium sulfate, bodied ferric sulfate
Plant or combination in any.
It is a further object to provide the preparation method of a kind of use in waste water treatment demulsifier, comprise the steps:
Step (1): isobutanol, sodium hydroxide and initiator are simultaneously introduced, control temperature, at 30～60 DEG C, continues stirring
2～3 hours；
Step (2): the reactant of step (1) is mixed with ethyoxyl polysilane, and stirs 1～2 hour；
Step (3): above-mentioned product is added and remains other material and be sufficiently mixed, obtain use in waste water treatment demulsifier.
Beneficial effects of the present invention:
(1) present invention is possible not only to effectively have deoiling effect, and has flocculation concurrently, greatly reduces oily waste water
The back-end processing load of water, its practicality is stronger；
(2) preparation technology is simple, with low cost.
Detailed description of the invention
