Leachate back-spraying system

Abstract

The invention relates to the technical field of waste liquid spray treatment equipment and relates to a leachate back-spraying system. The system comprises a leachate collecting pool communicated witha garbage pool; the leachate collecting pool is communicated with a leachate intermediate storage tank; the leachate intermediate storage tank is communicated with an incinerator; a conveying pump set is arranged between the leachate intermediate storage tank and the incinerator; a filtering tank set is arranged between the leachate collecting pool and the leachate intermediate storage tank; theleachate collecting pool is communicated with a conveying pipe; the filtering tank set comprises a first filtering tank communicated with the conveying pipe, a second filtering tank communicated withthe first filtering tank and a third filtering tank. According to the leachate back-spraying system of the invention, leachate enters the leachate collecting pool; the leachate in the leachate collecting pool can sequentially enter the first filtering tank, the second filtering tank and the third filtering tank; the three filtering tanks can fully filter the leachate; the good spraying effect of spraying of a spraying gun is guaranteed, and meanwhile it is guaranteed that the whole back-spraying system is smoothly carried out.

Description

Technical field [0001] The invention relates to the technical field of waste liquid spray treatment equipment, in particular to a leachate back spray system. Background technique [0002] Leachate (also called leachate) is in the process of municipal solid waste incineration or landfill. Due to compaction and the action of microorganisms, the pollutants contained in the garbage will be dissolved out with water and together with rainfall, runoff, etc. form. [0003] The water quality of the leachate is more complicated, not only contains aerobic organic pollutants, various metals and phytonutrients (ammonia nitrogen, etc.), but may also contain toxic and harmful organic pollutants, and the concentration of pollutants in the leachate is relatively high and varies in range Large, COD and BOD can reach tens of thousands. The leachate generally needs to be treated before it can be discharged. In the prior art, an effective method for purifying the leachate is post-processing after fil...

AI Technical Summary

Problems solved by technology

[0005] Although the above technical solution can spray the leachate after filtration, the impurity in the leachate is only filtered through the filter during the spray treatment, and the impurity content in the leachate is relatively large, so the filter Filtration requirements are relatively high, and the filter alone may not be able to filter out the impurities remaining in the leachate

Therefore, the impurities remaining in the leachate may block the spray gun or pipeline, which will cause the spray gun to fail to spray liquid smoothly, resulting in the failure of the entire backspray system to run smoothly
