Example Embodiment

[0021] Example 1

[0022] A method for detecting the decontamination efficiency of feather velvet fine washing water, including the following steps:

[0023] (1) The first-stage treatment of feather down essence washing and recycling water, the second-stage treatment of feather down essence washing and recycling water, down essence washing drainage and tap water sampling 1L, adding 2.5g compound detergent; stirring well, putting it in the water bath slowly Heat to 40°C to obtain the solution to be tested, set aside.

[0024] The composition of the composite detergent: anionic surfactant, nonionic surfactant, and foam stabilizer in a mass ratio of 10:2:0.5.

[0025] (2) Use a Roche foaming instrument to test the foaming performance of the solution to be tested; test the maximum foam volume and foam stability value (read the foam height after the foam is stable for 5 minutes) three times each, and take the average value; specific operation In order to stabilize the water temperature in...

Abstract

The invention discloses a method for detecting decontamination efficiency of feather down fine washing reuse water. The method includes sampling feather down fine washing reuse water and running water, adding a compound detergent respectively to obtain solutions to be tested, testing foaming performance of the solutions to be tested respectively with a Ross Miles foam analyzer, and finally detecting decontamination efficiency of feather down fine washing reuse water. Compared with the prior art, reverse thinking is adopted in the method, i.e.testing the foaming performance of feather down fine washing reuse water with the same detergent under the same testing condition so as to detect decontamination efficiency of the feather down fine washing reuse water. According to the method, analysis of compositions of feather down fine washing reuse water solution is not required, test procedures are reduced, degree of operational difficulty of testing is lowered, and detection accuracy of decontamination efficiency of feather down fine washing reuse water is increased.

Description

technical field [0001] The invention belongs to the field of down fine washing, and in particular relates to a method for detecting the decontamination efficiency of water used for down fine washing. Background technique [0002] The down fine washing process consumes a lot of water. If the water reuse technology for fine washing is not implemented, the cost of production enterprises will be greatly increased. At the same time, there will be great waste of water resources and environmental pollution. [0003] The drainage water quality after fine washing of down feathers contains oily substances, short down, ash and other components from feather washing, which has high biochemical properties. The research proves that the activated sludge biochemical treatment process can be used to treat fine washing wastewater, and the sewage after activated sludge biochemical treatment can meet the water quality discharge requirements. If the biochemically treated water continues to be us...
