Description
Technical Field
The invention relates to the technical field of environmental protection and resource regeneration and comprehensive utilization, in particular to a zero-emission recycling treatment method for organic waste liquid.
Background
The tin-stripping waste liquid is one of various organic waste liquids, is also one of typical wastes in the PCB industry, belongs to dangerous waste liquid which is generated in the PCB production process, has very high acidity, contains a large amount of metal compounds such as tin, copper, iron and the like, and various organic matters such as a stabilizer, a corrosion inhibitor and the like, and has complex components.
The invention patent of patent application publication No. CN 108070720B discloses a comprehensive recovery method of tin-stripping waste liquid, which comprises the following steps: 1. decompressing and distilling the tin-stripping waste liquid to recover nitric acid therein to obtain distilled residual liquid, and recovering tin powder from the distilled residual liquid; or directly adjusting the pH value of the tin stripping waste liquid to recover tin powder; 2. oxidizing the Fenton reagent to remove organic matters in the solution after tin removal; 3. extracting, electrolyzing or evaporating to extract copper; 4. removing iron and lead from raffinate; 5. evaporating and recovering the sodium nitrate.
Compared with the prior art, the method mainly solves the problems that the comprehensive recovery rate of tin, copper and other substances is not high, the process is complex, secondary pollution is high and all components in the tin-stripping waste liquid cannot be fully recovered in the tin-stripping waste liquid recovery process.
However, the above method finds some disadvantages after being actually used by those skilled in the art, and it is obvious that when the crude tin powder is separated from the distillation residual liquid by centrifugation or filtration, a certain amount of distillation residual liquid remains on the surface of the crude tin powder, and the remaining of the distillation residual liquid not only causes the surface of the crude tin powder to be moist and easily oxidized, which is not favorable for subsequent storage, but also causes the crude tin powder in a moist state to be more inconvenient to take out from the inside of the filtration device, which increases the operation difficulty and also easily causes incomplete recovery.
In addition, the residual distillation residual liquid does not meet the direct discharge standard, so that secondary pollution is easily caused when the residual distillation residual liquid is cleaned subsequently.
Therefore, it is necessary to invent a zero-emission recycling treatment method for organic waste liquid to solve the above problems.
