WASTEWATER TREATMENT EQUIPMENT AND WASTEWATER TREATMENT METHOD

To provide a wastewater treatment equipment or the like capable of obtaining vaporization-concentrated water which is less likely to cause trouble during transport to a solid content generation part and which is capable of efficiently generating a deposit at the solid content generation part.SOLUTION: A wastewater treatment equipment includes a vaporization concentration part to obtain vaporization-concentrated water by carrying out vaporization concentration treatment of wastewater, and a solid content generation part to generate a solid content from the vaporization-concentrated water. The vaporization-concentrated water is designed to be transported from the vaporization concentration part to the solid content generation part. The wastewater includes a soluble component that becomes a deposit by concentration. The solid content including the deposit is generated at the solid content generation part. Termination time of the vaporization concentration treatment is determined at the vaporization concentration part by at least one of relative density, moisture content and conductivity of the vaporization-concentrated water being subjected to the vaporization concentration treatment.SELECTED DRAWING: Figure 1 【課題】 固形分生成部への移送時にトラブルを起こしにくい蒸発濃縮水であって、固形分生成部において効率的に析出物を生成できる蒸発濃縮水を得ることができる排水処理設備などを提供することを課題としている。【解決手段】 排水に対して蒸発濃縮処理を施して蒸発濃縮水を得る蒸発濃縮部と、蒸発濃縮水から固形分を生成させる固形分生成部と、を備え、蒸発濃縮部から固形分生成部へ蒸発濃縮水が移送されるように構成され、排水は、濃縮によって析出物となる溶解成分を含み、固形分生成部では、析出物を含む固形分が生成され、蒸発濃縮部では、蒸発濃縮処理が行われている蒸発濃縮水の比重、含水率、又は導電率の少なくとも１つによって蒸発濃縮処理の終了時が決定される、排水処理設備などを提供する。【選択図】 図１
