• Water supply:
  The water source of the existing project is supplied by the local centralized water supply project. The water used in the existing project is mainly domestic water and boiler water, and the fresh water consumption is 6.0m³/d.
• Boiler water replenishment:
  The project uses the reverse osmosis process to prepare soft water. The fresh water consumption of the soft water equipment is 5.2m3/d, and the soft water 3m3/d is used for boiler water replenishment.

The 12 t/h premix feed mill in United States project waste gas was mainly dust generated in the production process and gas boiler flue gas.

• During the production process of the project, the pellet unloading process will generate dust. The dust is collected through a gas collecting hood on the top of the pellet discharge pit and then processed by a bag dust collector.
• Dust will be generated in the initial cleaning of granules, the initial cleaning of powder, the warehouse to be crushed, the batching warehouse, and the warehouse to be granulated. Each generation point is equipped with an air collection hood and shares a bag dust collector. The designed air volume is 12000m3/h.
• The crushing process will produce dust, which needs to be treated with 1 air collection hood + 1 cyclone dust collector + 1 bag dust collector + 1 15m high exhaust pipe (P2). The design air volume of the cyclone dust collector and bag dust collector is 6000m3/ h.
• The hopper feeding process of the mixer will generate dust. It is equipped with an air collecting hood and is processed by a bag dust collector. The designed air volume of the bag dust collector is 3000m3/h.
• The countercurrent cooling and granulation process will generate dust. The dusty waste gas is collected by a gas collecting hood and processed by a bag dust collector. The design air volume of the bag dust collector is 5000m3/h.
• The blanking process during packaging will produce a certain amount of dust. The dusty exhaust gas is collected by a gas collecting hood and processed by a bag dust collector. The bag dust collector has a designed air volume of 3000m3/h.

The USA premix feed plant project set up a 0.5t/h gas steam boiler for granulation heat, and the factory set up a 1.2m3 LNG (0.5t) storage tank to store compressed natural gas. The sulfur content of the natural gas used in the project was 200mg/m3.

The project year The gas consumption is 84,000m3, and the main pollutants in the flue gas generated are SO2, NOX and particulate matter. The flue gas is emitted from an 8m high chimney.

The project produced no production wastewater. The wastewater was mainly boiler soft water equipment drainage, employee toilet wastewater and boiler drainage. Domestic sewage is mainly employee toilet wastewater with simple water quality.

It is temporarily stored in a 30m3 sedimentation tank in the factory area and used for factory greening and dust suppression, with little impact on the surrounding water environment.

The noise of the 12 t/h premix feed mill in United States project was mainly the noise of production equipment, and the noise values of the original project equipment were between 75dB-95dB.

By banning whistles in the factory area, selecting low-noise equipment, installing basic shock absorption, and sound insulation of the factory and other measures, and after distance attenuation, the company's existing test report shows that the daytime noise range at the factory boundary of this project is 52.3 ~57.4dB (A), in line with the Category 2 standard (daytime ≤ 60dB (A)) in the "Environmental Noise Emission Standard for Industrial Enterprises at Boundaries".

The noise at the factory boundary meets the requirements of the "Environmental Noise Emission Standard for Industrial Enterprises at Factory Boundaries" (Class 2 standard) and has little impact on the surrounding acoustic environment.

The solid waste generated by the 12 t/h premix feed mill in United States project mainly includes debris generated by the initial cleaning of the screen, the initial cleaning of granular materials, and the initial cleaning of powder materials, material dust removal, iron filings generated by the permanent magnet cylinder iron removal process, and employee domestic waste.

Among them, the dust, iron filings and debris are general industrial solid waste. The dust removal of the materials is collected and reused for production. The iron filings are collected and sold for comprehensive utilization.

The debris is collected and handed over to the environmental sanitation department for unified processing. Domestic waste is collected centrally. It will then be handed over to the environmental sanitation department for unified processing.

During the operation period of the project, all solid waste will be properly disposed of and will not have any adverse impact on the surrounding environment.
