Problems solved by technology

For the test of the transparency of reused water, it is greatly affected by the tester; for COD and BOD, the test operation is complicated, the test time is long, and the price is high, which will increase the production cost of the enterprise
The biggest problem with the above test method is that it only pays attention to the clarity of the reused water, the amount of reductive and biodegradable organic matter contained in it, and does not directly answer the question of whether the quality of the reused water will affect the fine cleaning performance in the next use

Embodiment 1

[0022] A method for detecting the decontamination performance of water used for fine washing of feather and down, comprising the following steps:

[0023] (1) Take a sample of 1L of water for the first-stage treatment of feather and down fine washing, and the second-stage treatment of the water for feather and down fine washing. Heated to 40°C to obtain the solution to be tested for use.

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

[0025] (2) Carry out the test of the foaming performance of the solution to be tested with the Roche Foaming Apparatus; respectively test the maximum foam volume and the foam stability value (read the foam height after the foam is stable for 5 minutes), and take the average value respectively; specific operations To: keep the temperature of the water in the graduated tube (jacketed measuring cylinder) stable at 40±0.5°C, rinse the inner wall of the g...

Embodiment 2

[0047] The detection sample is tap water, and the steps of Example 1 are repeated to test the foaming stability of the composite detergent.

[0048] The foaming stability performance test (unit: ml) of compound detergent of table 5

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...
