Abstract

Abstract

In order to solve the problems existing in traditional centralized treatment system, such as heavy workload, high maintenance cost and resource waste, hydrothermal carbonization in source separation treatment of toilet blackwater was studied. A treatment system of toilet black water based on hydrothermal carbonization was proposed. Subsequently, the test was set up at five temperature gradients of 200, 210, 220, 230, and 240 ℃, and two reaction residence times of 20 min and 30 min. The vacuum filtration time of the reaction product and the moisture content of the filter residue were analyzed and compared. The results showed that the time of vacuum filtration was longer than 3 minutes under the conditions of 200 ℃-20 min, 200 ℃-30 min and 210 ℃-20 min. The remaining reaction conditions were less than one minutes. With the increase of reaction temperature, the water content of filter residue decreased. The cost and energy consumption of the system were estimated with 200 person/day. The system cost and per capita processing cost were 103000 RMB and 0.08 RMB, respectively. Finally, it was pointed out that the solid products could be used as resources, the wastewater and exhaust gas could be treated by vacuum evaporation and catalytic combustion respectively.
