The issue of enterprise pollution prevention has drawn the attention of relevant departments. Proper water pollution prevention efforts can effectively mitigate the expansion of water contamination. Therefore, it is crucial to understand the requirements for pollutant discharge pipelines and water supply pipelines in enterprise water pollution prevention facilities. This article will delve into these requirements.
What are the requirements for pollutant discharge pipelines?
1.Different types of pollutant discharge pipelines, from the source to the wastewater treatment facilities, must be distinguished using different colors.
2.Arrow-labeled rectangular identification color signboards should be used on pollutant discharge pipelines to indicate the main pollutants and flow direction of the wastewater.
3.Where should pollutant discharge pipelines be labeled? Key locations include the starting point, intersections, turns, wall penetrations, valves, and endpoints of wastewater pipelines.
4.Pollutant discharge pipelines must be installed as exposed piping. If underground trenches are used, measures must be taken to prevent rainwater ingress, and the trench covers should facilitate inspection and maintenance.
5.All similar wastewater streams must converge into a single pipeline before entering the treatment facilities, with only one discharge pipeline allowed.
6.Flow meters must be installed for all types of wastewater before they enter the treatment facilities to monitor the wastewater content.
7.Initial rainwater must be directed to the comprehensive wastewater treatment station for processing to ensure all parameters meet standards before discharge.
8.No other pollutant discharge pipelines should be laid within rainwater drainage channels.
9.The routes of rainwater and domestic sewage drainage systems must be clearly marked on the ground in white, with inspection points set up as required.
10.All pollutant discharge pipelines must be fixed, and any abandoned pipelines must be dismantled.
Having covered the requirements for pollutant discharge pipelines, what about the requirements for water supply pipelines? These are relatively fewer, with the following four points:
1.Enterprise water supply pipelines are primarily divided into three types: domestic water, industrial water, and firefighting water. Each type must have a separate water meter to record usage.
2.All water supply pipelines must be clearly labeled in accordance with GB7231 standards.
3.In existing water supply systems, if outdoor firefighting water pipelines are combined with domestic and industrial water pipelines under low-pressure conditions, the number of valves for converting industrial water to firefighting water must not exceed two. These valves should be installed in easily accessible locations, clearly marked, and equipped with water meters to record the conversion volume.
4.For newly constructed pollution sources, firefighting water systems must not be combined with domestic and industrial water supply pipelines.
As a manufacturer of water quality online monitoring instruments, Hangzhou Modi–Tech would like to remind relevant personnel that after preliminary water pollution prevention efforts, wastewater treatment and water quality monitoring remain essential. Key areas include domestic sewage monitoring, medical wastewater online monitoring, and industrial process water monitoring.
