1. Overview of public pollution treatment facilities in Vietnam industrial parks

Industrial parks in Vietnam are usually equipped with public pollution treatment facilities to ensure that wastewater, waste gas and solid waste from enterprises in the park can be effectively treated. The main function of these facilities is to centrally treat pollutants generated by enterprises in the park and reduce the impact on the environment. The following is a detailed assessment of public pollution treatment facilities in Vietnam’s industrial parks.

2. Processing power

2.1 Wastewater treatment capacity

The wastewater treatment facilities in the industrial park are usually designed according to the scale of the industrial park and the number of enterprises. The treatment capacity usually ranges from thousands to tens of thousands of cubic meters per day. A combination of physical, chemical and biological treatment processes is used to remove suspended solids, heavy metals, organic pollutants, etc. in the water. The treated wastewater must meet Vietnam’s national discharge standards, and some industrial parks may have stricter internal standards.

2.2 Waste gas treatment capacity

Centralized waste gas treatment facilities may be set up in the industrial park, especially in chemical and heavy industrial parks. Adsorption, absorption, catalytic oxidation and other technologies are used to remove harmful substances in waste gas. The treated waste gas must meet national and local emission standards.

2.3 Solid waste treatment capacity

Facility types include landfills, incinerators and resource processing facilities. Processing process Solid waste needs to be collected and sorted, some can be recycled, and the rest needs to be treated harmlessly. Supervision requirements The park needs to regularly report waste treatment to the environmental protection department and accept inspections.

3. Cost Assessment

3.1 Processing Fees

The industrial park usually charges treatment fees based on the amount of wastewater, waste gas and solid waste discharged by the enterprise. The charging standards may vary depending on the difficulty of treatment and technical requirements. Including fixed fees and volume-based charges, some industrial parks may provide preferential policies to encourage enterprises to reduce emissions. Enterprises can reduce treatment costs by reducing emissions and improving the resource utilization rate of waste.

3.2 Government Subsidies

Some industrial parks may receive government subsidies to reduce the processing costs of enterprises, especially in the application of environmental protection technologies and facility upgrades. For enterprises that adopt advanced environmental protection technologies and achieve emission reduction targets, the industrial park may provide additional fee reductions or subsidies.

4. Special requirements for Vietnam Industrial Park

4.1 Stricter emission standards

Some industrial parks may set stricter emission standards than national standards to ensure higher environmental quality. Enterprises are required to adopt treatment technologies and equipment that meet industrial park standards.

4.2 Centralized treatment facilities

Enterprises in the park are required to use centralized treatment facilities to reduce the cost and complexity of individual enterprises’ own treatment. The park management agency is responsible for the daily operation and maintenance of the facilities to ensure the efficient operation of the treatment facilities.

4.3 Regular review and update

Enterprises are required to submit emission and treatment reports regularly and accept the review of the park and environmental protection department. According to the latest environmental protection requirements and technological developments, the park may require enterprises to participate in the upgrading and transformation of facilities.
