The invention provides a dehydration and refining method and system for aged oil. The dehydration and refining method comprises the following steps: (1) carrying out primary extraction on aged oil byusing a primary extractant, then carrying out solid-liquid separation to obtain a primary extraction liquor and a primary extraction residue, wherein the component of the primary extractant comprisesan oleophilic hydrophilic organic solvent with a boiling point of 100 DEG C or below; (2) recovering the primary extractant in the primary extraction liquor, carrying out oil-water separation on the residual liquid to obtain a first oil phase and a first aqueous phase; and (3) carrying out secondary extraction on the primary extraction residue by using a secondary extraction agent, and then carrying out solid-liquid separation to obtain a secondary extraction residue and a secondary extraction liquor containing a second oil phase, wherein the component of the secondary extractant comprises polycyclic aromatic hydrocarbon. The method has good dehydration effect, high crude oil recovery rate, short process time and high separation efficiency, and has obvious advantages compared with the prior art.

The invention discloses a method for preparing and using a strippable cellulose-based radioactive pollution decontamination agent, which is characterized by: a. modifying the pre-prepared cellulose ether by grafting; then using the prepared fiber The detergent was prepared from the ether grafted product. b. Spray the decontamination agent evenly on the surface of the radioactively contaminated material, dry at 20-60°C for 15-22 hours to form a film, and peel off the film to complete the decontamination process. The detergent provided by the invention uses cellulose with abundant resources as a raw material, has a simple preparation method, and has obvious decontamination effect, and can resist a certain dose of radiation and show easy peeling and good decontamination properties; further is , After decontamination, the solid waste can be biodegraded or incinerated, with a high capacity reduction rate, which is convenient for storage and solidification treatment, meets the requirements of sustainable development, and has great economic and social benefits.

The invention relates to a solid waste plasma gasification treatment device and method. The treatment device includes a plasma gasification furnace, a secondary combustion chamber, a condenser, a spray tower and a bag filter; Second combustion chamber, condenser, spray tower and bag filter. The plasma gasification furnace is vertically inserted with a liftable plasma torch on the top to gasify solid waste and produce a large amount of synthesis gas; the synthesis gas is fully burned in the secondary combustion chamber to remove organic pollutants in the flue gas, such as dioxin Ying et al.; the flue gas after combustion first passes through the condenser to cool down rapidly to avoid the generation of dioxins, and then remove the acidic substances in the flue gas. Finally, through the bag filter, it can ensure that the treated flue gas reaches the treatment target. The system of the invention utilizes plasma to rapidly raise the temperature, and has the characteristics of strong raw material adaptability, full combustion, and thorough removal of pollutants; it is suitable for treating various solid wastes.

The invention discloses a method for muddy water dredging and in-situ efficient volume reduction and a device for achieving the method. A dredge pump (1), a two-stage serial hydrocyclone system (III), a coagulant mixing adding system (II) and a centrifugal hydroextractor (IV) are arranged on a dredge ship. The centrifugal hydroextractor is directly connected with the two-stage serial hydrocyclone system. Muddy water is drawn and dredged through the dredge pump (1) on the dredge ship and fed into the two-stage serial hydrocyclone system for concentration volume reduction treatment, concentrated underflow mud obtained after volume reduction is discharged into the centrifugal hydroextractor to be dehydrated, and overflow clear liquid is directly drained into water. Mud cakes obtained after dehydration are lightered to land to be treated, one part of dehydration filter liquor is reused in the coagulant mixing adding system (II), and the rest is directly drained to the water. The method for muddy water dredging and in-situ efficient volume reduction and the device for achieving the method are small in size, small in occupied area and high in solid-liquid separation efficiency, and effluent can be directly drained into the water.

The invention relates to a marine kitchen garbage treatment device. In the invention, an automatic control box controls a motor to be connected with a worm reducer so as to drive a blender in a machine body through a belt transmission device at one end of the machine body; the machine body above the blender is provided with a charging cover; the machine body is externally wrapped with an electricheat tracing belt; a discharging cover corresponding to the position of the blender is arranged on the side wall of the machine body; the machine body is internally provided with a filter screen; theinner cavity of the machine body is communicated with an induction unit through the filter screen and a three-way catalytic converter; the induction unit is connected with a suction inlet of a fan; and both the electric heat tracing belt and the fan are connected with the automatic control box. According to the invention, blending and strains are coordinated in the enclosed machine body to sufficiently digest the kitchen garbage; the mesophilic digestion environment in the machine body and the deodorization of the tail gas three-way catalytic converter are coordinately controlled to realize effective volume reduction and harmless treatment of the marine kitchen garbage; the device has the advantages of rational design and convenient and safe operation, so as to ensure that the volume reduction rate of the harmless treatment of the kitchen garbage is high and the tail gas discharge is pollution-free, therefore, the device is suitable for the marine kitchen garbage treatment.
