Embodiment 1

[0064]Randomly pick up fresh urine from an adult as a treatment sample, shake it well, weigh 1.000kg of urine on a balance into a distillation bottle, add 5.0mg of potassium persulfate and 2.30mL of concentrated sulfuric acid in sequence, mix well, and conduct urine Then install the distillation bottle on a rotary evaporator, set the temperature of the water bath at 59°C, set the rotation speed at 27rpm, carry out vacuum distillation at -0.09~-0.1MPa, collect the distillate, and obtain the product.

Embodiment 2

[0066] In order to verify the treatment effect of the treatment method of the present invention on the urine of different sampling personnel, this embodiment randomly selects the fresh urine of another adult as the treatment object, shakes it well and weighs 1.000kg of urine in a retort, and adds Mix 5.0 mg of potassium persulfate and 2.30 mL of concentrated sulfuric acid, then install the distillation bottle on a rotary evaporator, set the temperature of the water bath at 59 ° C, set the speed at 27 rpm, and conduct vacuum distillation at -0.09 to -0.1 MPa to collect Distillate, that is.

Embodiment 3

[0068] In order to verify the treatment effect of the treatment method of the present invention on the urine of different sampling personnel, this embodiment randomly selects the fresh urine of the third adult as the treatment object, shakes it well and weighs 1.000kg of urine in a retort , add 5.0 mg of the above potassium persulfate and 2.30 mL of concentrated sulfuric acid and mix well, then install the distillation bottle on a rotary evaporator, set the temperature of the water bath at 59 ° C, set the speed at 27 rpm, and depressurize at -0.09 to -0.1 MPa Distillation, distillate collection, that is.

Abstract

The invention relates to the technical field of urine recycled water treatment, in particular to a treatment method for purifying urine recycled water. The treatment method for purifying the urine recycled water comprises the steps of utilizing a composition of peroxysulphate and concentrated sulfuric acid as a pretreatment agent for pretreating urine; carrying out reduced pressure distillation oratmospheric distillation treatment on the pretreated urine. Compared with the original urine, the water productivity of a distillate exceeds 91.2 percent, meanwhile, 94.11 percent or more of salt and95.6 percent or more of organic matters in the urine can be removed, and a strong technical support is provided for water recycling treatment of the urine.

Description

technical field [0001] The invention relates to the technical field of urine regeneration water treatment, in particular to a treatment method for purifying water in urine. Background technique [0002] Water resources are an essential resource for human life, and one of the most precious resources that nature bestows on human beings. However, with the increasing industrial pollution, the shortage of water resources has become increasingly prominent. Especially in an environment where specific water resources are particularly precious, water sources are scarce or water costs are very high, and people's water consumption only depends on water storage and frequent and regular replenishment, which is uneconomical and unrealistic, and requires water recycling and water regeneration Only technology can realize the recycling of water. How to maximize the reuse of potential water resources has become a key technology to solve the problem of water shortage under specific environme...
