摘要： A multi-stage distillation plant consisting essentially of a multi-flash evaporator provided with a multi-flash chamber which is divided into a heat recovery section and a heat rejection section. In this multi-stage flash distillation plant, the aforesaid flash evaporator is provided with a deaerator for deaerating cold sea water, a thickener for separating brine containing a relatively great amount of seeds, from concentrated brine which has been extracted from a front chamber of the final stage flash chamber, and a seed mixing tank for obtaining a seed-mixed brine, whereby part of the sea water which has passed through the deaerator is supplied as a feed sea water to the rear chamber of the final stage flash chamber, while the brine containing a relatively great amount of seed and extracted from the thickener is joined to the seed-mixed brine fed from the seed mixing tank. Thus, the confluent brine thus joined together is discharged for deaeration into the final stage flash chamber from a distributor provided in the rear chamber thereof. According to another aspect of the invention, the aforesaid deaerator is omitted and the feed sea water which has not been subjected to deaeration is joined to the aforesaid confluent brine and is discharged for deaeration from the distributor.

摘要： The present invention relates to an apparatus for removing suspended matter, organic matter and nitrogen compounds in the sewage. A processing tank is provided with a floating-separation zone at the upper portion thereof and an electrolysis zone below the floating-separation zone. A bed of porous adsorbent is disposed in the electrolysis zone and electrodes are disposed among the adsorbent. Bubbles generated upon the feed of current to the electrodes rise up through the floating-separation zone to remove the suspended matter and the organic matter in the sewage before introducing the sewage into the electrolysis zone. The porous adsorbent is polarized by the feed of current to the electrodes and results in removing matter remaining in the sewages, especially nitrogen compounds.
