Embodiment 1

[0036] The pretreatment composition for the treatment of urine regeneration water described in this embodiment includes:

[0037] Potassium persulfate 5.0mg and concentrated sulfuric acid 2.30mL.

[0038] The preparation method of the pretreatment composition for urine regeneration water treatment described in this embodiment includes mixing the potassium persulfate, concentrated sulfuric acid and urine.

[0039] Randomly pick fresh urine from an adult as a treatment sample, shake it well and take 1.000kg of urine, add 5.0mg of potassium persulfate and 2.30mL of concentrated sulfuric acid to it, mix well, and carry out urine pretreatment.

Embodiment 2

[0041] The pretreatment composition used for the treatment of urine regeneration water described in this example is the same as in Example 1. In order to verify the treatment effect of the composition of the present invention on the urine of different sampling personnel, this example randomly selects another adult's Fresh urine is the object of treatment. Shake well and take 1.000kg of urine, add 5.0mg of the above potassium persulfate and 2.30mL of concentrated sulfuric acid to it and mix well to pre-treat the urine.

Embodiment 3

[0043] The pretreatment composition used for the treatment of urine regeneration water described in this example is the same as that in Example 1. In order to verify the treatment effect of the composition of the present invention on the urine of different sampling personnel, this example randomly selects a third adult Fresh human urine is the object of treatment. Shake well and take 1.000kg of urine, add 5.0mg of the above potassium persulfate and 2.30mL of concentrated sulfuric acid to it and mix well to perform urine pretreatment.

Abstract

The invention relates to the technical field of urine recycling water treatment, and in particular relates to a pretreatment composition used for urine recycling water treatment as well as a preparation method, applicable ratio and application of the composition. The pretreatment composition used for the urine recycling water treatment provided by the invention uses potassium persulfate and concentrated sulfuric acid as effective ingredients, and the composition can be used for purifying pretreatment of urine; after pretreatment is performed, the urine is subjected to distillation, and a distillate has the water production ratio of 91.2% or more compared with original urine; and the composition can remove 97.2% or more of salts and 95.6% or more of organic matter in the urine. Compared with a urine purifying pretreatment method in the prior art, the method provided by the invention not only has stable quality and uses cheap raw materials easy to obtain, but also has a small medicine using amount, ideal water production ratio and ideal removing effects on the salts and the organic matter, and provides powerful technical support for water regeneration treatment of the urine.

Description

technical field [0001] The invention relates to the technical field of urine regeneration water treatment, in particular to a pretreatment composition for urine regeneration water treatment and its preparation method and application. Background technique [0002] Water resource is an essential resource in human life, and it is also 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 techn...
