Description

Technical field

This invention belongs to the field of hazardous waste processing, more specifically, it relates to a device for processing hazardous liquid waste.

Technical problem

The technical problem that this invention solves is how to construct a device for the treatment of hazardous waste in a liquid or semi-liquid state, such as waste from water-oil separators, sludge from oil separators, waste containing oil, waste water containing dangerous substances, waste water and concentrated waste water resulting from the decontamination of groundwater, and especially waste water containing oily substances, whereby waste treatment can be carried out "in situ".

State of the art

In the area of hazardous waste treatment defined by the above text, there are several solutions, which use different filters with sorption materials, which can be renewable (reusable), or disposable, where they are incinerated after use. Most of these plants are bulky, which means that the medium to be purified must be transported to the plant in order to perform its purification, whereby, before the decision on purification is made, the waste must be concentrated at the disposal site.

The essence of the invention

It has been found that the shortcomings described in the above situation can be largely eliminated by applying a waste treatment device according to the technical solution described by this invention, which consists of a tank that receives the purification medium at one end, while releasing the purified medium at the other end. The tank is technologically divided by transverse walls into at least two, and preferably three chambers, which enable three levels of purification. Since the waste material (under pressure) is introduced into the first chamber in which the foam sediment removal partition and coalescing filters are located in the direction of the purification medium flow, and a relative decrease in the inflow occurs, the sedimentation of mechanical pollutants in this chamber and the partial separation of oily substances, which stand out on the surface, occur. The medium is then subjected to purification on coalescing filters and introduced into the second chamber where the sorption filters are placed. The purification medium is subjected to sorption filtration in this chamber, and then, if necessary, in the third chamber, the purification process is completed by filtration on activated carbon. The medium is then carried to the recipient through the system of outlet pipes through the sewage chamber.

The resulting hazardous waste can be further processed by one of the known methods, for example biodegradation.

It is desirable that the tank at the entrance to the feed has a filter for separating coarse waste (GPT) from the purification medium before entering the first chamber.

On the upper wall of the tank there are openings that allow control of the technological process and potential interventions.

For the device, sorption filters in commercial use, such as sorption liners and sorption baskets, can be used.

The main advantage of this device is that, thanks to its dimensions, it can be placed on a mobile support structure. This quality allows hazardous waste to be treated at the place of origin.

Detailed description with performance examples

Example 1

The device according to the mentioned technical solution was used to remove non-polar substances whose extraction is possible {non-polar extractable substances or NES) from water in the production facility in Dongjin Sebes God-Ujtelep ZJ-2. It was determined that the level of pollution by non-polar substances according to the ŠPP ORG-MV-06 GC type A method is 2,212,306 mg/l and the appropriate technological procedure was defined. The flow rate of the purification medium is regulated by the system. The device consists of a tank 1 with a derived inlet 11 by means of which the medium for purification is introduced under pressure, and an outlet 12, at the other end, for the output of the purified medium. Reservoir 1 is technically divided by partition walls into three working chambers 13, 14 and 15. In the first chamber there are placed a partition for removing foam sediment 131 and a coalescing filter 132 in the direction of the flow of the purification medium. In the second working chamber 14 are placed two sorption filters 141 and 141', which have the form of sorption baskets. Openings 171, 172 and 173 are made on the lid of the tank, which allow to monitor the purification process and to carry out potential external interventions, such as, for example, the replacement of contaminated sorption liners with new ones. A filter 151 with activated carbon is placed in the third working chamber.

Since the material for purification is introduced under pressure into the first chamber 13 in which the partition for removing the foam sediment 131 and the coalescing filter 132 are placed in the direction of the flow of the medium for purification, and a relative reduction in the inflow occurs, the sedimentation of mechanical pollutants in this chamber and the partial separation of oily substances on the partition for removing the foam sediment 131, and their separation on the surface. The medium is then subjected to purification on the coalescent filter 132 and introduced into the second chamber 14 in which the sorption filters 141 and 141' are placed, in the form of sorption jackets. The purification medium is subjected to sorption filtration in this chamber, and then in the third chamber 15, the purification process ends with filtration on activated carbon. The medium is then carried to the recipient through the drain 12 through the system of outlet pipes through the sewage chamber. The device is placed on a specially adapted support structure.

The level of pollution by non-polar substances (NES) according to the ŠPP ORG-MV-06 GC type A method at the exit from the mobile waste treatment device was 0.420 mg/l.

Example 2

The device according to the mentioned technical solution was used for the purification of oil-contaminated water in the production facility in Dongjin Sebes G6d-Ujtelep ZJ-2. It was determined that the level of pollution with non-polar substances according to ŠPP ORG-MV-06 GC type A method is 2,212,306 mg/l and the appropriate technological procedure was defined. The flow rate of the purification medium is regulated by the system. The device consists of a tank 1 with a derived inlet 11 by means of which the medium for purification is introduced under pressure, and a drain 12, at the other end, for the output of the purified medium. The tank 1 is technically divided by partition walls into three working chambers 13, 14 and 15. In the first chamber, a partition for removing foam sediment 131 and a coalescing filter 132 are placed in the direction of the flow of the purification medium. Two sorption filters 141 and 141', which have the form of sorption baskets, are placed in the second working chamber 14. Openings 171 and 172 are made on the lid of the tank, which allow the purification process to be monitored and potential external interventions to be carried out, such as, for example, the replacement of contaminated sorption liners with new ones. A filter with active carbon is placed in the third working chamber.

Since the material for purification is introduced under pressure into the first chamber 13 in which the partition for removing the foam sediment 131 and the coalescing filter 132 are placed in the direction of the flow of the medium for purification, and a relative reduction in the inflow occurs, the sedimentation of mechanical pollutants in this chamber and the partial separation of oily substances on the partition for removing the foam sediment 131, and their separation on the surface. The medium is then subjected to purification on the coalescent filter 132 and introduced into the second chamber 14, where the sorption filters 141 and 141' are placed in the form of sorption jackets. The medium is then carried to the recipient through the drain 12 through the system of outlet pipes through the sewage chamber. The device is placed on a specially adapted support structure. In this case, filtration on the active line

not executed.

The level of pollution by non-polar substances (NES) according to the ŠPP ORG-MV-06 GC type A method at the exit from the mobile waste treatment device was 4,754 mg/l.
