II. Implementation of requirements on environmental protection facilities and measures of the projects

The required environmental protection facilities and measures have been built and put in place according to EIA requirements, and the environmental protection facilities and measures were as follows:

1. For waste gases:

(1) Waste gases from the production line for water-based adhesives

Waste gases from the production line for water-based adhesives mainly come from the processes of materials feeding, reaction and canning. For each of the steps, gas gathering devices have been installed to collect the waste gases. The main pollutants therein are volatile organic compounds and particulates, which are continuously discharged. And the waste gases are collected intensively, treated by a set of down-flow filter cartridge dust collectors in the workshop and then by a set of molecular sieve adsorption and concentration runner +RTO devices commonly used by the factory before being discharged through an exhaust pipe of 15m in height.

(2) Waste gases from the production line for canning

The waste gas generated from the production line for cans mainly come from the welding, glue injection and coating drying. For each of the processes, gas gathering devices have been installed to collect the waste gases. And the main pollutants in the waste gases are non-methane total hydrocarbons and particulates which are continuously discharged. The waste gases are collected intensively, treated by a set of down-flow filter cartridge dust collectors in the workshop and by a set of molecular sieve adsorption and concentration runner +RTO devices used in the factory before being discharged through an exhaust pipe of 15m in height.

(3) Waste gases from the production line for wood paints

The waste gases produced in the production line for wood paints mainly come from the feeding and canning processes. For each of the processes, gas gathering devices have been installed to collect the waste gases. The main pollutants therein are non-methane total hydrocarbons, particulates, toluene and xylene, which are continuously discharged. The waste gases are collected intensively, treated by a set of down-flow filter cartridge dust collector in the workshop and by a set of molecular sieve adsorption and concentration runner +RTO devices commonly used in the factory before being discharged through an exhaust pipe of 15m in height.

(4) Waste gases from the production line for curing agents

For curing agents only a simple dilution process is involved, and the waste gases produced from the production line for curing agents mainly come from feeding and canning. For each of the processes, gas gathering devices have been installed to collect the waste gases. The main pollutants therein are non-methane total hydrocarbons, particulates, toluene and xylene, which are continuously discharged. Also the waste gases are collected intensively, treated by a set of down-flow filter cartridge dust collectors in the workshop and by a set of molecular sieve adsorption and concentration runner +RTO devices commonly used in the factory before being discharged through an exhaust pipe of 15m in height.

(5) Waste gases from boiler

A 2t/h steam boiler is designed in the project using natural gas as fuel from which the main pollutants are SO2, NOx, particulates, etc., which are discharged through an exhaust pipe of 10 meters in height.

2. Waste water:

For the project rain and waste water are separated. And the waste water mainly includes water from equipment cleaning, floor flushing and domestic sewage produced by employees in the workshops for production of water-based adhesives.

Both the waste water from production and domestic sewage will enter the sewage treatment station in the factory with a treatment capacity of 200m3/d. And water from equipment cleaning, floor washing and domestic sewage of employees in the workshop for production of water-based adhesives is discharged into the sewage treatment station together with water from the production lines for emulsion paints, water-based wood paints, natural stone texture paints, water for cleaning of putty powder equipment and floor washing at the Phase I project, which is treated by "high efficiency air flotation+micro-electrolysis", and then discharged together with domestic sewage.

3. Noise and solid waste:

For the projects measures have been taken such as sound insulation, noise elimination and vibration reduction against the main sources of noise; solid wastes are collected and stored in a standardized way, and hazardous wastes are handed over to qualified units for disposal.

III. Results of assessment before approval from monitoring and investigation

According to the Environmental Protection Monitoring Report on Assessment and Approval of Construction Projects (Chuan Huan Jian Yan Zi (2017) No. YS17040) prepared by Sichuan Environmental Monitoring General Station, the conclusion of assessment and approval by monitoring is as follows:

1. Waste gases
