Embodiment 1

[0057] A high-salt desalination evaporation equipment, refer to figure 1 , according to the order of leachate treatment, including pretreatment unit, DTRO unit and evaporation unit. The leachate discharge is irregular, and the water quality is also significantly different. Therefore, before the leachate desalination treatment, it needs to flow into the adjustment tank first, and in the adjustment tank, the water volume and water quality of the leachate tend to be stable after staying, deflecting, aeration and mixing. state.

[0058] The pretreatment unit includes a coagulation sedimentation tank and a stripping tower arranged through pipelines in sequence, and the water inlet end of the coagulation sedimentation tank is connected with the regulating tank. By adding flocculants into the coagulation sedimentation tank, the flocculants include but not limited to polyferric chloride and polyaluminum sulfate, so that the particles that are difficult to settle in the leachate are a...

Embodiment 2-5

[0084] A high-salt desalination evaporation equipment differs from Example 1 in that the selection of admixture, coarse aggregate, and fine aggregate is different, and the input amount of each raw material is different. See Table B for details.

[0085] Form B

[0086]

Embodiment 6

[0088] A kind of high-salt desalination evaporation equipment, the difference with embodiment 5 is that the admixture is that slag powder and silicon powder are mixed in a ratio of 1: 0.2 by weight, that is, the input amount of slag powder is 40kg, and the input of silicon powder The amount is 8kg.

Abstract

The invention relates to the field of sewage desalination and evaporation, in particular to high-salt desalination and evaporation equipment and a high-salt desalination and evaporation method. The high-salt desalting evaporation equipment comprises a DTRO (Disk Tubular Reverse Osmosis) unit and an evaporation unit, the DTRO unit comprises a sand filter system, a two-stage DTRO membrane and a degassing tower, the water inlet end of the sand filter system is connected with the adjusting tank, the water outlet end of the sand filter system is connected with the two-stage DTRO membrane, and the two-stage DTRO membrane is connected with the degassing tower; the evaporation unit comprises an MVR evaporation system, a precipitation standing pool and a dryer, the MVR evaporation system is respectively connected with the degassing tower and the precipitation standing pool, the precipitation standing pool is connected with the dryer, and the dryer is connected with the adjusting pool. The method has the advantage that the problem that the salt content of the landfill leachate is high is solved.

Description

technical field [0001] The application relates to the field of sewage desalination evaporation, more specifically, it relates to high-salt desalination evaporation equipment and methods. Background technique [0002] At present, landfill, incineration and composting are the main treatment methods for municipal solid waste. The sanitary landfill method has the advantages of large processing capacity, wide application range, simple process, low cost and mature technology, and has become a recognized waste disposal technology. During the landfill process, due to the moisture carried by the garbage itself, the decomposition of organic matter during anaerobic decomposition, the immersion of groundwater, and the leaching of rainwater, a large amount of highly polluting and refractory landfill leachate is produced, which contains a large amount of Organic matter, heavy metal salts and ammonia nitrogen, so landfill leachate must undergo necessary treatment to avoid pollution to the...
