II. Project construction content

the project is a new project. The main construction content is: two single-layer light steel plants, warehouses, office buildings, etc. see Table 1 for the technical and economic indicators of the project planning and table 2 for the construction content of the project

Table 1 technical and economic indicators of the project planning

1. Construction period

the development and construction period of the whole plot of the project will take about 2 years. During this period, it will inevitably have a certain impact on the surrounding environment, mainly focusing on the noise of construction machinery, the noise of incoming and outgoing transport vehicles, dust on roads and construction sites, stacking of construction waste, etc., especially in the absence of strict management, Pollution control measures will be more prominent if they are not implemented in place

2. During the completion and operation period

the main production pollutants of the project come from the smoke and SO2 produced by gas generators and glass kilns, the dust produced by batching machines and mixers, and the oil smoke produced by staff canteens. After treatment, they can be discharged up to the standard. The waste water is mainly domestic sewage. If there is no information signal, it should be easy to find out that the production waste water is discharged. Noise equipment mainly includes air compressors and various fans. The solid wastes are mainly waste glass, which can be recycled, and the coal cinder can be comprehensively utilized. The tar residue is sold, and the tar residue is sent to a qualified unit for disposal. In addition, the domestic garbage is sent to a landfill for disposal

see Table 3 for the summary of pollutant emissions during the operation period of the project

Table 3 summary of pollutant emissions unit: t/a

a. noise

the construction unit of the project shall strictly implement the law of the people's Republic of China on the prevention and control of noise pollution and GB noise limits at the boundary of construction sites, adopt low-noise construction equipment and advanced technology for construction, and adopt static pressure piles for foundation piling. At the same time, the working hours of various construction machinery must be reasonably arranged during construction, and the application and approval procedures for night construction must be carefully implemented and reported to the environmental protection department for filing

b. fugitive dust

during construction, special attention shall be paid to the prevention and control of construction fugitive dust, and necessary prevention measures shall be developed to reduce the impact of construction fugitive dust on the surrounding environment

c. waste water

the construction unit shall connect the sewage pipe before construction. A large amount of slurry water and rainwater generated during construction contain a large amount of SS. All external drainage must be settled in the tank before being discharged into the urban sewer, so as to avoid the blockage of the urban sewer

d. solid wastes

during the construction period of the project, it is necessary to transport waste soil and various building materials (such as sand, stone, cement, brick, wood, etc.), which will produce a large amount of waste soil, brick and various construction wastes. The solid wastes must be transported to the designated points for proper disposal in time to prevent the creation of new "waste yards"

2. Pollution prevention and control measures during operation period

a. air pollution prevention and control measures

(1) dust treatment

① the transportation of raw materials is mainly airtight, mechanized and automated. Transfer points have been minimized in the design, and pneumatic transportation is used to transport powder

② dust hoods are set at each dust raising point. Each batching system is equipped with three bag type dust collectors with a processing air volume of 2800~3000m3/h, with a dust removal efficiency of 99%. After treatment, the dust emission concentration is 100mg/m3, the emission is 0.149kg/h, and the annual emission is 1.28t

(2) treatment of flue gas from the gas producer

the gas producer is equipped with a cyclone dust removal system in the products purchased from the manufacturer. The environmental impact assessment of the project suggests that the desulfurization tower on the gas producer should adopt the activated carbon desulfurization technology, so that the smoke and SO2 in the local waste gas can be discharged up to the standard

(3) treatment of kiln dust and SO2 waste gas

the gas produced by the gas generator is sent to the glass furnace as fuel after dedusting and desulfurization. The smoke concentration in the flue gas is 51 mg/m3 and the SO2 concentration is 100mg/m3, meeting the class II emission standard in the emission standard of air pollutants for industrial kilns (GB)

key new functional materials and device R & D and utilization, advanced structure and composite utilization and other projects will also be launched

(4) canteen oil fume treatment

the designed exhaust volume of the canteen of this project. Therefore, the energy consumption cost in the plastic granulation industry has become the second largest cost in the plastic granulation cost after raw materials, which is 8000nm3/h. If the oil fume purification device with a treatment efficiency of 80% is adopted, the oil fume emission is 0.015t/a and the emission rate is 0.014kg/h. The generated concentration is 8.75mg/m3, and the discharge concentration is 1.75mg/m3, which can meet the discharge standard

b. prevention and control measures for wastewater pollution

the wastewater of the project mainly includes staff domestic wastewater, ground flushing wastewater and a small amount of phenol containing wastewater

circulating cooling water is used for the cooling of gas generators, glass kilns, machine-made molding machines, air compressors and other equipment in the project. The circulating water is reused and will not be discharged

a certain amount of phenol liquid will be produced in the process of gas production of the project, i.e. gas condensate. This part of waste water has a small amount, and its production is about 1.2m3/d. The main pollutant is phenol. The concentration of phenol in the phenol liquid is between 300~500mg/l. For such high concentration and low emission phenol containing waste water, the common domestic practice is to recycle all the phenol liquid to the gas generator for recycling and combustion, and incinerate it

in this project, the ground flushing water can be recycled or discharged as workshop ground flushing water after sedimentation. The ground flushing water mainly contains SS, which can be discharged after sedimentation in the sedimentation tank

for the treatment of domestic sewage in this project, the EIA suggests to use the buried powered domestic sewage treatment device for treatment. After treatment by this device, the effluent quality can meet the requirements of class I discharge standard in the integrated wastewater discharge standard (GB)

c. noise pollution prevention countermeasures

(1) for the batching, mixing and conveying mechanical equipment and dust removal fans in the raw material workshop, sound insulation and double-layer sound insulation glass shall be adopted for the plant building, and separate operation room and monitoring room shall be set up; Sound insulation cover and shock absorption foundation shall be adopted for dust removal fan

(2) water pump

the water pump shall be low-noise equipment, connected with soft joints, and the pump base shall be equipped with damping pads, or the circulating water pump shall be set in a separate sound insulation room with damping foundation

(3) air compressor noise

unit silencing: mufflers with a certain amount of noise shall be installed at the air inlet, exhaust port and vent port

sound insulation of station building: if necessary, air compressor room can be set and certain sound insulation and absorption measures can be taken

(4) fan noise

for power equipment such as fans, low-noise equipment will be selected as far as possible, and appropriate supporting noise elimination, vibration reduction and sound insulation devices will be adopted

if necessary, the fan room can be set and certain sound insulation and absorption measures can be taken

(5) general layout and greening

reasonable general layout is an effective measure to reduce noise pollution. Reasonable greening can also reduce noise pollution. Planting all kinds of evergreen hardwood around the high noise section can reduce the impact of noise on the external environment

d. prevention and control measures for solid waste pollution
