Problems solved by technology

[0003] Municipal solid waste includes kitchen waste, fruit and vegetable waste, and other domestic waste, which contains a large amount of organic solid waste, landfill leachate and other organic waste water, oily water, and heavy metal waste. Oxygen fermentation or aerobic fermentation, etc., but it is difficult to treat sewage, it occupies a large area, it is difficult to process residual fertilizers, and the treatment efficiency is low. high energy consumption, low processing efficiency, and high processing difficulty

Embodiment 1

[0029] A process treatment method and system for oily water treatment and desalination of garbage:

[0030] 1) Degreasing unit: For components including the lipophilic film and the disc, the lipophilic film and the disc are stacked one after the other (such as figure 1 As shown in the combination of lipophilic film and disc), the oil and water first pass through the lipophilic film to absorb the oil, and the adsorbed oil is removed by rotating the disc through the rotating machine to degrease the garbage;

[0031] The lipophilic membrane is made of electrospun nanofiber membrane, epoxy-modified silicone resin, acrylate and hydrophobic hydroxyethyl cellulose, the proportions are respectively 2:6:5:3, and the organic solvent DMF is used for dissolution. Thoroughly stir evenly and dry to form a film;

[0032] The porosity of the obtained lipophilic membrane is 70-80%;

[0033] 2) Deodorization unit: including degradative enzyme tank and photocatalyst material to degrade the bio...

[0039] A process treatment method for oily water treatment and desalination of garbage

[0040] Take 5kg of crushed municipal solid waste for the following treatment:

[0041] 1) Oil removal treatment: For the components including the lipophilic film and the disc, the lipophilic film and the disc are stacked in the form of one after the other, the oil and water first pass through the lipophilic film to absorb the oil, and the rotating disc removes the adsorbed oil Carry out degreasing treatment of garbage;

[0042] The lipophilic membrane is made of electrospun nanofiber membrane, epoxy-modified silicone resin, acrylate and hydrophobic hydroxyethyl cellulose, the proportions are respectively 4:8:2:2, and the organic solvent DMF is used for dissolution. Thoroughly stir evenly and dry to form a film;

[0043] The porosity of the obtained lipophilic membrane is 70-80%;

[0044] 2) Deodorization treatment: use degradative enzymes and photocatalyst materials to degrade and catal...

Abstract

The invention belongs to the technical field of garbage treatment, and particularly relates to a process treatment method and system for oil-water separation and desalination of garbage. The method comprises the following steps of 1) oil removal treatment: comprising combining a micron-sized oleophylic membrane with a disc, and removing oil in an oil absorption and rotation combined manner; 2) deodorization treatment: comprising conducting deodorization on the oil-removed garbage by adopting a degrading enzyme and a photocatalyst material; 3) desalination treatment: comprising conducting desalting and heavy metal removing by adopting a direct-current electrolysis mode; and (4) filtering and collecting: comprising filtering the treated garbage through a PVDF (Polyvinylidene Fluoride) plate-type membrane, and carrying out oxygenation treatment. By combining the oil removal treatment mode, the deodorization mode and the desalination mode with the PVDF plate-type membrane filtration and water drainage mode, separation of oil and water in garbage can be realized, peculiar smell is reduced, 30-40% of reduction is realized, and compared with the traditional technology, the method of the invention has the advantages of greenness, high efficiency, high utilization rate, recyclability, cost reduction and the like.

Description

technical field [0001] The invention belongs to the technical field of garbage treatment, and in particular relates to a process treatment method and system for oil-water separation and desalination of garbage. Background technique [0002] With the development of urban population and people's living needs, more and more domestic waste is produced. According to statistics from relevant agencies, in 2019, the country produced a total of more than 240 million tons of biomass waste, of which 37 million tons were municipal sludge, food waste There are 99 million tons of kitchen waste, 12.99 million tons of septic tank excrement, and 100 million tons of fruit and vegetable waste. Garbage siege has become a major problem for the government. [0003] Municipal solid waste includes kitchen waste, fruit and vegetable waste, and other domestic waste, which contains a large amount of organic solid waste, landfill leachate and other organic waste water, oily water, and heavy metal waste...
