2. Main production process and equipment for 240,000 tons per year feed mill factory plant for cattle & poultry

(1) Complete poultry and cattle fed production process

This large cattle & poultry feed processing plant project mainly produces feed for cattle and poultry. The raw materials (corn, soybean meal, fish meal, etc.) that meet the production requirements are purchased, and they are directly transported and stored in a vertical silo by conveying equipment in a sealed manner. The conveying device is used for feeding; It is sent to the bucket elevator by the scraper conveyor and lifted to the top of the main car, and iron is removed from the permanent magnet cylinder, and then sent to the silo for standby. The raw materials such as corn, soybean meal and other granular items are crushed by a crusher in the crushing section, and then sent to the respective intermediate storage bins after crushing. According to the ratio of the feed formula, all powdered raw materials (including feed additives, fish meal) are electronically metered from their respective intermediate bins and then sent to the double-shaft high-efficiency feed mixer for sufficient mixing, and the mixed powdered materials enter the pellets. Warehouse spare. The powdered material is fed into the granulator to pass steam for granulation. After granulation, it is cooled to room temperature by a countercurrent cooler. The finished product is sieved and then packaged. The sieved material is put into the raw material feeding port together with the raw material. Dust removal facilities are installed above the production equipment in the feeding, crushing, mixing, and screening sections of this project, and the collected dust is returned to the feeding stage for recycling.

3. Main pollution process

(1) Construction period:

①Exhaust gas: leveling the ground, bulk material storage yard, construction bare surface, dust caused by transportation vehicles and concrete mixers, will cause air pollution in the local environment.

②Wastewater: domestic sewage of construction workers, the main pollutants are COD, ammonia nitrogen, BOD5, etc.

③Noise: It comes from the noise generated by the mechanical equipment during the construction period and the noise generated by the transportation, which has a limited impact on the quality of the regional acoustic environment and is short-term and reversible.

④Solid waste: construction waste generated during construction and domestic waste generated by construction workers.

(2) Operating period:

①Exhaust gas: The exhaust gas of this project is mainly boiler flue gas and dust produced in the process of feeding, crushing, mixing and screening.

②Wastewater: There is no production wastewater in this project, and the main wastewater is domestic sewage from employees.

③Noise: The noise of this cattle and poultry feed machine plant project is mainly the mechanical noise generated by the operation of hoist, conveyor, grading screen, air compressor, fan and other poultry cattle feed equipment.

④Solid waste: The main solid waste of this annual output of 240,000 tons feed processing plant for cattle & poultry project includes dust collected by the dust collector during the production process, waste packaging materials, and domestic garbage generated by the cattle & poultry feed production factory staff.

4. Environmental impact analysis during construction period

(1) Construction dust

The dust generated during the construction period will have a short-term impact on the surrounding atmospheric environment. In order to reduce the impact of dust on the surroundings, the excavation and stacking of the earth must be standardized and orderly, and the spoil must be cleaned up and transported in time. The areas that cannot be cleaned up in time can be sprayed or covered to suppress dust. Loading and unloading in strong winds is prohibited. , The transportation and stacking of materials should be carried out in an organized and planned manner, and the open-air stacking of materials should be minimized. If it is necessary to store in the open air, temporary shelters, simple sheds or tarpaulins should be added around, etc., during construction, water should be properly sprayed before operation. Air pollution during the construction period is short-term and temporary. Once the construction is over, the dust will disappear.

(2) Wastewater

The wastewater generated during the construction period is mainly domestic sewage and construction wastewater. Domestic sewage is mainly cleaning wastewater, which produces a small amount; construction wastewater mainly comes from the washing of building materials such as loaders and stones, and the main pollutant is SS. According to the analog monitoring survey, the SS is 1000～3000mg/L. The discharge characteristic of this wastewater is intermittent discharge, and the amount of wastewater is unstable. The main pollutants in domestic sewage produced by construction workers are COD, BOD5, and NH3-N. It is recommended to establish a wastewater sedimentation tank, which is used to collect various types of wastewater discharged during construction. The wastewater can be reused as construction water after sedimentation in the sedimentation tank. This not only saves water resources, but also reduces pollution to the surface water environment.

(3) Noise

Noise pollution is the main environmental pollution during the construction period. The pollution is concentrated in the earthwork phase, foundation engineering phase, structural engineering phase and various construction phases. During the construction period, various noise sources are outdoors, which has a large impact on the surrounding acoustic environment, especially the noise generated by the pile driver. Construction noise is staged, temporary and unstable. Different construction equipment has different noise effects. When multiple mechanical equipment is operated at the same time, the noise generated by each equipment will be superimposed. In different construction stages, the noise superimposed value of various construction machinery is also different. See Table 10 for the main construction stages, noise sources and sound levels. During the construction period, the sound sources are all outdoors, with a long range of influence; during the decoration period, most of the sound sources are indoors, with walls blocking noise. Comprehensive analysis shows that construction noise is staged, temporary and unstable. Different construction equipment has different noise effects. When multiple mechanical equipment is operated at the same time, the noise generated by each equipment will be superimposed.

Because the mechanical noise travels far in the open area, the construction noise pollution is short-term and temporary. Once the construction is completed, the construction noise will disappear. Considering the source intensity superposition combination when the fixed strong noise source is used synchronously on the construction site, it is predicted that the possible combination influence distance will be about 50m during the day and 150m at night. Since construction is prohibited at night, a prescription at a distance of 50m from the noise source can meet the relevant regulations in the "Environmental Noise Emission Standard for Construction Site Boundaries" (GB12523-2011).

(4) Solid waste

The solid waste during the construction period is mainly the domestic garbage generated by the constructors and the construction garbage generated during the construction process. Construction waste mainly includes civil engineering waste, metal waste from decoration projects, etc. It is basically non-toxic and is general solid waste. It should be disposed of in accordance with local construction waste management methods. Civil engineering waste can generally be backfilled after construction. Metal waste from decoration projects Can be recycled and reused.

5. Environmental protection investment estimate

The total investment of large production capacity cattle and poultry feed manufacturing factory project is 120 million yuan, of which environmental protection investment is 1.37 million yuan, accounting for about 1.14% of the total investment.
