Recently, the Bureau of Ecology and Environment of Jiujiang City, Jiangxi Province, approved the environmental impact report on the change of the first phase of the public wharf project in Chihu Operating Area, West Port Area of Jiujiang Port City. It is understood that the wharf project is located in the riverside area of Chihu Industrial Park, Chaisang District, Jiujiang City, and the construction unit is Jiangxi 8893 Commerce and Trade Co., Ltd.
The project plans to build two 5000-ton general berths (the hydraulic structure is designed to berth 10000DWT ships), with an annual cargo throughput of 5.7 million tons and a designed annual throughput capacity of 6 million tons. Among them, the bulk import is 1.4 million tons/year, the bulk export is 4 million tons/year, the breakbulk import is 100,000 tons/year, and the breakbulk export is 200,000 tons/year. The bulk cargo includes sand and stone aggregate and iron ore, while the general cargo includes building materials, timber, textiles, prefabricated pipe piles, biomedicine and agricultural, forestry, animal husbandry and fishery products. It does not involve the transportation of dangerous chemicals. Occupying 245m of shoreline. The main environmental impacts of the
project and the countermeasures and measures to prevent or mitigate the adverse environmental impacts are as follows:
1. Waste water
project: bilge oil sewage of ships arriving at the port, ballast water of ships arriving at the port, The domestic sewage from ships arriving at the port shall be handed over to the ship pollutant receiving unit recognized by the local maritime department for centralized collection and disposal; The washing wastewater from the wharf platform enters the washing wastewater collection tank, and enters the self-built wastewater treatment station in the harbor area together with the vehicle washing wastewater after passing through the oil-water separator for treatment (with a design capacity of 50t/d), and the treatment process is "regulating sedimentation + coagulating sedimentation + filtration". After reaching the water standard for road cleaning and urban greening in the Reuse of Urban Recycling Water Water Quality Standard for Urban Miscellaneous Water (GB/T18920-2002), the water shall be reused for vehicle washing and dust suppression in the plant area, and shall not be discharged. The domestic sewage in
the port area is pretreated by oil separator and septic tank, and then enters the sewage treatment plant of Chihu Industrial Park for further treatment after meeting the water quality requirements of the sewage treatment plant of Chihu Industrial Park; The rainwater in the initial stage of the project is collected through the rainwater pipe network in the port area, and then diverted to the rainwater sedimentation tank (with a volume of about 4500 cubic meters) by the rainwater diversion well for treatment. After sedimentation treatment, the upper clear water is discharged to the rainwater pipe network (in rainy days) or reused for washing, dust suppression, greening, etc. In the port area. The clean rainwater in the later stage is collected to the municipal rainwater pipe network through the rainwater pipe network.
2. The waste gas produced by the waste gas
project is mainly the particulate matter produced by bulk cargo loading and unloading, transshipment and transportation, as well as the exhaust gas of automobiles and ships arriving at the port. Dust emission is controlled by a series of measures such as setting up closed bulk storage yard (spraying dust in the storage yard), closed transfer station (setting up dry fog dust suppression in the transfer station), closed conveying corridor, setting up wind shield (or closed chute) for loading and unloading machinery and dry fog dust suppression; In addition, the emission of pollutants from ships arriving at the port is reduced by selecting diesel oil with low sulfur content, reducing the operation load of auxiliary engines, and setting shore power facilities; the emission of dust and exhaust gas from ships arriving at the port is subject to the emission standard limits of Shanghai Integrated Emission Standard of Air Pollutants (DB31-933-2015).
3. Noise
This project further reduces the impact of noise on the surrounding environment by selecting low-noise equipment, taking sound insulation and vibration reduction measures, and optimizing the layout and setting up green belts.
4. Solid waste
This project does not accept the solid waste of ships arriving at the port. The solid waste of ships arriving at the port shall be entrusted to the ship pollutant receiving unit recognized by the maritime department for collection and disposal; The waste engine oil, waste engine oil drums, oil-containing rags and gloves collected by classification of the project shall be regularly transported and disposed by qualified units after being stored in the land hazardous waste temporary storage room. A hazardous waste temporary storage room with an area of about 5 square meters (volume of about 10 cubic meters) is set up beside the sewage treatment facilities in the
plant area, which can accommodate the hazardous waste of this project. The temporary storage room shall be designed, constructed and managed in strict accordance with the design principles of storage facilities, hazardous waste stacking specifications and other relevant requirements in the Standard for Pollution Control on Hazardous Waste Storage (GB18597-2023). The warehouse shall be sealed, windproof, rain-proof and sun-proof, and the ground shall be subject to anti-seepage treatment. The stored hazardous wastes shall be regularly handed over to qualified units for treatment. The solid wastes generated from
loading and unloading shall be comprehensively utilized by the rear storage yard; the iron-bearing sundries shall be temporarily stored and regularly sold after collection; the sludge generated by the sewage treatment station shall be sold or comprehensively utilized after drying; and the domestic garbage shall be daily cleaned and transported by the environmental sanitation department. A temporary storage room for general solid wastes (with a volume of about 20 cubic meters) covering an area of about 10 square meters is set up next to the sewage treatment facilities in the plant area, which can accommodate the general industrial solid wastes of the project. The storage process of general industrial solid waste shall meet the corresponding environmental protection requirements such as leakage prevention, rain prevention and dust prevention.
