The project is planned to start construction in October 2015, November 2015 completed use.

2 construction project on the environment may affect Overview
Construction dust, construction noise, construction waste water and solid waste: The project under reasonable control measures to strengthen the environmental management of the premise, the construction period will not cause a serious impact on the environment.

Exhaust gas: pour melted wax molding process to produce volatile organic waste (VOCs), when silver silver oil painting oil step, organic components of volatile oil silver organic waste generated by two 15m high exhaust emission purification after activated carbon adsorption, their emission rates, emission concentrations meet the Tianjin local standards "Industrial enterprises volatile organic emission control standards" (DB12 / 524-2014) limit requirements.

Pour molding process provided in the pickling process after processing chamber, electroforming process provided in the pickling process hanging indoor color, the use of a mixed solution of oxalic acid, hydrochloric acid and sulfuric acid are. Pickling washed with tap water, the pickling process carried out in a fume hood, oxalic acid and hydrochloric acid, sulfuric acid was produced volatiles. After all volatiles by lye purification device purifying spray absorption by the two 15m high exhaust emissions, their emission rates and emission concentrations meet the "Air Pollutant Emission Standards" (two) requirements.

The project to build a medium-sized two-story factory canteen, kitchen cooking process will produce a certain amount of smoke, mainly from cooking, frying and other food processing. After canteen fumes fume emission purification apparatus for processing, to meet the "cooking fume emission standards" (GB18483-2001) of 2.0mg / m3 requirements.

Wastewater: The project is mainly domestic sewage discharge wastewater and polish washing wastewater containing gypsum waste water cleaning, pour molding acid-containing cleaning water, lye spray mist scrubber wastewater wastewater. The project sewage through septic tanks, grease traps and sewage treatment facility by the plant after production mix treated wastewater, drainage water quality meet DB12 / 356-2008 "Integrated Wastewater Discharge Standard" (Grade 3).

Noise: The main noise source is the press, tableting machines, hydraulic machines, cable trombone machines, cars spend machines, washing machines, polishing machines and other equipment and ground source heat pumps, fans and other canteen soot emissions, which are set in the various production facilities inside the plant and the use of low-noise equipment, plant a variety of devices within the predicted noise source intensity of about 60 ~ 80dB (A), by building insulation, the external environment has little effect after the distance attenuation.

Solid Waste: Solid waste generated by the project in the factory classification, storage alone, after which the general packaging and other recyclable waste materials collected separately sold outside recycling sector recycling; cyanide waste, waste acid and acid washing wastewater containing silver , neutralization tank sludge, waste bottles, waste activated carbon and other hazardous waste disposal hazardous waste entrust qualified units unified disposal; collect gold dust, gold scrap, scrap, waste recycling paraffin; waste gypsum and silver recovered by the original supplier recycling; garbage removal by the local sanitation department unified process. Solid waste disposal project can be reasonably, it will not impact on the surrounding environment.

Point 3 to prevent or mitigate adverse environmental impacts of policies and measures
3.1 Construction Period

Dust control measures during construction: The construction of the dust is mainly decorative installation, construction dust construction garbage removal, transportation building decoration materials and equipment, such as produce. Therefore, the construction dust take timely watering, timely removal of construction waste and other measures to prevent and reduce the environmental impact of construction dust. The project in the renovation process, the use of protective equipment for decoration dust, while controlling the decoration and construction time. In summary, by strengthening construction management, taking over a series of measures can significantly reduce air pollution caused by construction.

Construction of noise control measures: Avoid at night (the day 22:00 to 6:00 the next day) of construction work generated serious noise pollution; use of low-noise machinery and equipment, while strengthening the maintenance and management of equipment to keep it in good working condition, the reduce noise pollution to a minimum, all types of machinery and equipment should stop working off the engine; strictly implement the relevant provisions of GB12523-2011 "Construction Site environmental noise emission standards" standards.

Construction of wastewater prevention measures: fewer construction workers sewage generation, relying on the existing plant sewers into municipal sewage pipe network; vehicle after removing silt washing wastewater reuse for construction site dust suppression. Less the amount of wastewater generated during construction, and water quality is simple, easy to handle, by taking the necessary measures to deal with no significant impact on surface water environment.

Construction of the solid waste prevention measures: focus stacking and promptly clean up, Sinotrans to the relevant departments designated place, to prevent secondary pollution outdoor long pile that may arise.

3.2 operation period
