Domestic Wastewater Regulation (QCVN 14: 2008/BTNMT)

What is the domestic wastewater regulation (QCVN 14: 2008/BTNMT)?

The domestic wastewater regulation QCVN 14: 2008/BTNMT was issued by the Ministry of Natural Resources and Environment in 2008 to specify the allowable limit values of pollution parameters in domestic wastewater before being discharged into the receiving environment.
This regulation applies to domestic wastewater discharged from residential areas, urban areas, industrial parks, villages, production, business and service establishments. The purpose of this regulation is to protect water resources and ensure the quality of water resources for human purposes.
Scope of application of QCVN 14: 2008/ BTNMT
  • This regulation applies to domestic wastewater after treatment discharged from residential areas, urban areas, industrial parks, craft villages, production, business and service facilities.
  • Not applicable to medical wastewater, industrial wastewater, stormwater overflow and other types of wastewater.

The provisions of QCVN 14: 2008/BTNMT

The regulation specifies the allowable limit value of pollution parameters in domestic wastewater before discharge into the receiving environment, including:
  • Temperature:
  • Color
  • Salinity
  • Alkali
  • Suspended Solids (TSS)
  • Sunfua
  • Amoni
  • Total Nitrogen
  • Total Phosphorus
  • Coliform
These parameters reflect the physical, chemical and microbial characteristics of domestic wastewater, affecting water quality.

The method of determining the value of pollution parameters

The standard specifies methods of sampling and sample analysis to determine the value of pollution parameters in domestic wastewater, including:
  • Temperature: On-site measurement with thermometer < 40 ℃
  • Color: Eye color comparison method < 50
  • Salinity: Capacitance measurement method < 1000 mg/ l
  • Alkali: pH titration method 5.5 – 9
  • Suspended solid (TSS): Dry weighing method < 100 mg/l
  • Sulfides: High performance liquid chromatography method < 1 mg/l
  • Ammonium: Voltage titration method < 10 mg/l
  • Total Nitrogen: Redox method < 40 mg/l
  • Total Phosphorus: Spectral adsorption method < 6 mg/l
  • Coliform: Colony count method < 5000 MPN/100ml
The meaning of the standard
  • Protect water sources, prevent and control water pollution caused by domestic wastewater.
  • Ensuring water resources meet standards and quality to serve the purposes of human activities.
  • It is the legal basis for state management agencies to inspect and inspect the compliance of organizations and individuals in waste discharge.
  • As a base for building domestic wastewater treatment works to meet standards

Subjects must comply with domestic wastewater regulation

  • Production, business and service facilities that generate domestic wastewater must have standard wastewater treatment measures before being discharged into the environment.
  • Urban areas, residential areas, industrial parks and villages must have centralized wastewater collection and treatment systems that meet standards before being discharged into the environment.
  • Concentrated wastewater treatment facilities must operate treatment systems to ensure that the wastewater output is always up to standard.
  • Organizations and individuals when discharging wastewater into water sources must observe, analyze and keep records in accordance with regulations.
  • State management agencies are responsible for inspection and inspection of compliance of organizations and individuals. Strictly handle cases of violations and environmental pollution.
Thus, the domestic wastewater regulation QCVN 14: 2008/BTNMT clearly specifies the permissible limits of pollution parameters in wastewater before discharge into the environment. Compliance with the provisions of the regulation is essential, helping to protect water resources and human living environment. All organizations and individuals must be responsible for treating wastewater in accordance with regulations before discharge into the environment.

Analysis unit for measurement of pollution in domestic wastewater

The analysis and measurement of pollution in domestic wastewater must be carried out by units with certificates of analysis and wastewater monitoring prescribed by the state to meet standards. Since then, the new analysis indicators ensure the standards set by the state, avoiding harming the environment.
