The maximum allowable discharge concentration of pollutants in the water of the enterprise and the maximum allowable discharge volume of the landscape are the natural and age-related pollutants. The concentration is gradually increasing. The chemical oxygen demand (mR:L) of the product is the standard and classification.

Sampling In natural rubber processing enterprises, permanent non-discharge detection and wastewater sampling devices must be installed at the outlet:
5.2 Sampling frequency
The sampling rate should be determined according to the production period. Within the production period, the sampling rate should be once every 2 production periods, and once every 1 production period. The daily average discharge concentration is the highest permissible concentration. 5.3 Drainage water
The production volume is based on the full number of tons of products or the highest permissible non-water volume. The monthly average is calculated. 5.4 Statistics
The output of raw materials and products of the enterprise, etc., shall be based on the monthly or annual report: 5.5
