It should be noted that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments.

Example one
Referring to fig. 1 to 2, the present embodiment discloses a method for harmless minimization of hazardous waste, which includes the following steps:
1) the dangerous waste 1 is piled up in a centralized way, and a reaction container 2 for disposing the dangerous waste 1 is arranged outside the pile of the dangerous waste 1;
2) separating the stack of the dangerous waste 1 to separate the stack of the dangerous waste 1 into a block serving as a to-be-treated area, judging the state of the dangerous waste 1 in the to-be-treated area, and selecting one of the step 2A) and the step 2B) to implement;
2A) if the dangerous waste 1 in the area to be treated is solid and stable enough, the isolation treatment is not carried out;
2B) if the dangerous waste 1 in the area to be treated is in a liquid-like unstable state, building a fixed bank 3 between the area to be treated and the pile of the dangerous waste 1;
3) adding a harmless comprehensive treatment agent into the reaction container 2 in proportion, transferring the dangerous waste 1 in the area to be treated into the reaction container 2, mixing and stirring the dangerous waste 1 with the harmless comprehensive treatment agent, realizing the harmless treatment of the dangerous waste 1, and standing and curing;
4) building a wall body 4 around the treated area to be treated to enclose, and connecting and enclosing the wall body 4 and the part of the dike 3 which is bordered to form a reaction enclosed area 5;
5) repeatedly carrying out the steps 2) to 2A) or the steps 2) to 2B) on the adjacent area of the reaction enclosed area 5, adding a harmless comprehensive treatment agent into the reaction enclosed area 5 in proportion, transferring the dangerous waste 1 in the area to be treated into the reaction enclosed area 5, mixing and stirring the dangerous waste 1 with the harmless comprehensive treatment agent, and realizing the harmless treatment and standing solidification of the dangerous waste 1;
6) and (5) repeatedly carrying out the steps 4) to 5) until all the dangerous waste 1 in the stack of the dangerous waste 1 is harmlessly treated and solidified.
The present invention is most characterized in that the hazardous waste 1 is not simply put in a container for reaction treatment, but the hazardous waste 1 is divided into a plurality of blocks for batch treatment by a construction method, and a bank 3 is built at a boundary to separate the blocks if necessary, thereby stabilizing the hazardous waste 1.
Aiming at the hazardous waste 1 to be treated, the invention has the characteristics of extremely strong acidity or alkalinity, and extremely low or high pH value in general; the physical state is between oil state and solid state, the physical state change between different blocks is complex, and the oily hazardous waste 1 has high viscosity and a large amount of components. If most of the hazardous waste 1 in the block is oily, once the construction work is carried out by the excavating machine to transfer the hazardous waste 1 to the container, the hazardous waste 1 is dumped and spread from the gap in a large amount, and the work site becomes difficult to control and even damaged. In view of the instability of the hazardous waste 1, the operation site is inconvenient to use heavy operation equipment, and the operation difficulty is increased.
Therefore, the operation scheme of the invention is to stabilize the stack of the hazardous waste 1 and control the flowing of the hazardous waste 1. Specifically, in the step 2), the hazardous waste 1 in the divided areas to be treated is judged, and whether the physical state is stable enough is judged. In general, if the temperature and the humidity of the site are appropriate, the state of the hazardous waste 1 tends to be a solid state relatively, and is stable; if the conditions in the field are severe, the hazardous waste 1 may be melted into an oil-like liquid state by the influence of temperature, humidity, etc., and its stability is insufficient for the field treatment work. If the state of the dangerous waste 1 is not stable enough, the flow of the dangerous waste 1 pile can be stopped by constructing the bank 3 to prevent the dumping, so that the dangerous waste 1 can be conveniently transferred and the harmless comprehensive treatment agent is added to carry out stirring reaction in the step 3). On the premise that the dangerous waste 1 in the area is separated stably, operation of the operation machine on the dangerous waste 1 pile can be even realized, operation difficulty is greatly reduced, and the utilization rate of the machine is improved. If the hazardous waste 1 itself in the area is relatively stable in physical state, the isolation measure can be omitted to further enhance the process of the harmless operation. Then, the invention adopts the operation mode of gradually separating the stack of the dangerous waste 1, and repeatedly implements the steps 4) to 5) to carry out the following steps on the dangerous waste 1 one by one: stabilization, harmless treatment and solidification. And (5) repeating the process from the step 4) to the step 5), namely, performing harmless treatment on the dangerous waste 1 by regional emptying and transferring to an adjacent region, and then changing the originally emptied region into a new reaction enclosed region 5, so that the operation can be continuously extended until all the dangerous waste 1 is completely subjected to harmless treatment.
Preferably, in the step 1), the reaction vessel 2 is a reaction tank made of cement. The reaction vessel 2 is not necessarily cement-based in principle, but since the amount of the hazardous waste 1 is large, it is preferable to construct a cement-based reaction tank on site to improve efficiency. In addition, in the step 1), the hazardous waste 1 is preferably relatively intensively piled in the dug stockpiling pit to be treated, so that the stability of the pile of the hazardous waste 1 can be further improved, and the operation is facilitated.
The present invention innovatively uses the hazardous waste 1 itself as a raw material for the construction method of the bank 3. Referring to fig. 3, preferably, the step 2B) includes:
2B.1) digging a groove 6 extending along the boundary at the edge of the area to be processed;
2B.2) adding a mixture of the harmless comprehensive treatment agent and the hazardous waste 1 into the groove 6, and standing and curing the mixture in the groove 6 to form a curing block 7 with the shape matched with that of the groove 6;
2B.3) in situ sedimentation of the solidified blocks 7 obtained in step 2B.2) into the pile of hazardous waste 1;
2b.4) repeating steps 2b.1) to 2b.3), constructing the bottom layer of the bank 3 along the boundary;
2B.5) digging a groove 6 extending along the boundary above the bottom layer of the bank 3 in the step 2B.4), adding a mixture of a harmless comprehensive treatment agent and the hazardous waste 1 which are fully mixed into the groove 6, standing and curing the mixture in the groove 6 to form a curing block 7 with the shape matched with the groove 6, and making the curing block 7 sink onto the bottom layer of the bank 3 until a plurality of layers of curing blocks 7 are stacked to form the complete bank 3.
When step 2b.1) is carried out, the recess 6 is excavated, which corresponds in practice to the creation of a "mould" at the parting line for the production of the solidified mass 7. Then step 2B.2) is carried out, because the hazardous waste 1 reacts with the harmless comprehensive treatment agent, the hazardous waste is finally solidified into a hard and stable solidified block 7 after being harmlessly treated, and the process of standing and solidifying is generally over 12 hours. The shape of the solidified blocks 7 corresponds to the shape of the recesses 6, which corresponds to the "bricks" used to form the banks 3. In step 2b.3) and step 2b.5), the solidified block 7 is settled due to its own weight because the exhaust gas reactant is not solid. In order to make the sedimentation smoother, in step 2b.1), the bottom of the groove 6 is preferably in a sharp knife edge shape, that is, the bottom of the bottom solidified block 7 is in a knife edge shape, and the bottom of the bottom solidified block 7 discharges the dangerous waste 1 during the sedimentation process. When the viscosity of the hazardous waste 1 below the solidified block 7 is too high to be settled, the solidified block 7 can be settled downwards by digging the hazardous waste 1 below the solidified block 7 through an excavator in the step 2B.3) and the step 2 B.5).
Specifically, the above-mentioned harmless comprehensive treating agent includes a neutralizing agent, a coagulating agent and a comprehensive treating agent. Since the hazardous waste 1 is a highly corrosive substance of strong acid or strong alkali, a neutralizing agent is required for the neutralization reaction. The coagulant can solidify the dangerous waste 1 into hard and stable solidified blocks 7, and is also an important ingredient of the harmless comprehensive treatment agent in the invention. The comprehensive treatment agent is mainly used for stabilizing heavy metals, mineral oil and the like in the hazardous waste 1.
As a further preference, the harmless comprehensive treatment agent can also be added with a flocculating agent. The flocculant is mainly applied to the treatment of polluted water bodies to remove harmful pollutants dissolved in polluted liquid, so that the harmful pollutants are gathered and solidified to be separated from the water bodies.
Furthermore, the harmless comprehensive treatment agent also comprises a compacting agent, and the compacting agent has the function of gathering and compacting the internal tissues of the dangerous waste 1, so that the solidified hazardous waste has smaller volume and lighter weight, and the storage space is saved. The densification agent is also called as a weight reducing agent, and has a certain shrinkage rate in a densification effect, so that the hazardous waste 1 stacked in a large area can be changed into a harmless condensate with a reduced volume proportion after being treated, and the hazardous waste can be conveniently stacked in a smaller occupied area.
Since the specific components of the harmless comprehensive treatment agent are prepared according to the needs and are not the technical key points of the invention, the specific components and the proportion of the harmless comprehensive treatment agent are not repeated.
According to the harmless reduction treatment method for the hazardous waste, provided by the invention, the hazardous waste 1 is subjected to large-scale centralized treatment on the operation site, the efficiency is high, and the hazardous waste 1 can be harmless and can be stably solidified. Unique construction operation forms stable structure, and this stable structure is built through the solidification piece 7 that hazardous waste 1 self innoxious formation forms, makes hazardous waste 1 pile keep stable, prevents that hazardous waste 1 from pouring and diffusing, the field operation of being convenient for.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
