Embodiment Construction

[0020] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.

[0021] The invention provides a rapid detection method for high-concentration ammonia nitrogen and heavy metals in industrial wastewater, comprising the following steps:

[0022] (1) Take wastewater samples according to standard sampling methods;

[0023] (2) The detection and evaluation rate of wastewater samples shall be determined according to the production cycle. If the production cycle is within 8 hours, sampling shall be performed every 2 hours; if the production cycle is greater than 8 hours, sampling shall be performed every 4 hours. The maximum allowable dischar...

Abstract

The invention discloses a quick detection method for high concentration ammonia and nitrogen and heavy metals in industrial wastewater. The quick detection method comprises the following steps: (1) sampling a waste water sample by a standard sampling method; (2) determining the detection frequency of the waste water sample according to a production period, and sampling the sample once every 2h with the production period within 8h, sampling the sample once every 4h with the production period longer than 8h, and calculating the highest permitted discharged solution according to a daily average value; (3) filtering the waste water sample, removing precipitates and solid suspensions in the waste water, and adding activated carbon to further adsorb and settle to obtain waste water clean liquor;(4) detecting the content of heavy metals in the waste water by mean of a heavy metal detection device; and (5) carrying out an absorbancy experiment on the waste water sample to determine the ammonia nitrogen content in the waste water. Compared with the prior art, the method can detect the ammonia nitrogen content and the heavy metal content, the detection sensitivity is higher than that of a conventional testing method, and the detection method is quicker, more intuitive, easy to operate, low in cost and accurate and stable in testing result.

Description

technical field [0001] The invention relates to a detection method for industrial wastewater, in particular to a rapid detection method for high-concentration ammonia nitrogen and heavy metals in industrial wastewater. Background technique [0002] Water is the blood of industry, but with the development of industry, the waste water produced is becoming more and more serious, which is an important cause of environmental pollution, especially water pollution. Therefore, industrial wastewater must meet certain standards before it can be discharged or enter wastewater treatment plants for treatment. The detection of industrial wastewater is mainly the general term for the detection of wastewater, wastewater and aquatic organisms discharged from the production process of the enterprise factory. Process wastewater testing includes production wastewater and production sewage. Traditional chemical and physical analysis methods can quantitatively analyze the content of main compon...
