1. Insect pests are contaminated.
Insect pests can cause loss of feed nutrients or leave toxins in the feed. In the case of suitable temperature and high humidity, mites are more harmful to feed. Rodent damage not only causes loss of feed, but also causes feed pollution and spreads diseases.
2. Microbial contamination.
The feed breeds harmful microorganisms such as Aspergillus flavus, Gibberella and Fusarium, which produce toxins such as aflatoxin, gibberellin and gibberellin which are harmful to livestock and poultry. Among them, aflatoxin is the most toxic.
3. Anti-nutritional factor pollution.
Anti-nutritional factors in feed mainly include protease inhibitors, carbohydrate inhibitors, mineral element bioavailability inhibitors, antagonistic vitamin action factors, and stimulating animal immune system action factors. Their presence can interfere with the digestion, absorption and utilization of feed nutrients by livestock and poultry.
4. Harmful chemical contamination.
It mainly includes three types of harmful chemical substances such as pesticide pollution, industrial “three wastes†pollution, and nutritive mineral additive pollution.
5. Non-nutritive additive contamination.
The effects of antibiotics, hormones, antioxidants, anti-mold agents and sedatives have a great effect on preventing diseases, improving feed utilization and growth rate, but if the principles of use are not strictly adhered to and the safe use and withdrawal time are controlled, the drugs and Its metabolites remain in meat, eggs, and milk, and pollute the environment through livestock waste.
6. Cross-contamination of poisons generated during processing.
Improper control of the processing technology, complex additives in the feed in the special processing such as crushing, conveying, mixing, granulating, puffing, etc. will undergo degradation reactions, redox reactions, etc., to produce some complex compounds.
In addition, contaminant contamination in feed production is also an important factor affecting feed hygiene and quality. Therefore, in the process of feed processing, care should be taken to clean the equipment to avoid decomposition and residue of the feed during transportation and mixing.
Super-low Ash Coal Activated Carbon
coal-based activated carbon for water purification is widely used in the deep purification of drinking water, industrial water and wastewater. Industrial water purification and gas phase adsorption, such as power plant, petrochemical, oil refinery, food and beverage, sugar wine, medicine, electronics, fish, marine and other industries water purification treatment, can effectively absorb the water in the free, sulfur and other organic pollution special The price of the coal-activated carbon filter material, especially the precursor of the Mutant (THM), is to purify the impurity and remove the odor. can also be used for industrial exhaust purification, gas desulfurization, petroleum catalytic reforming, gas separation, pressure swing adsorption, air drying, food preservation, gas masks, media carrier recovery solvent Coal activated carbon, industrial solvent filtration, decolorization, purification and so on.
Use: Used in the purification of drinking water, deodorizing, brewing industry, decoloring of pharmaceutical and chemical products.
