The invention relates to an animal husbandry sewage flocculating agent with natural ingredients. The animal husbandry sewage flocculating agent is prepared from, by weight, 3%-15% of chitosan, 10%-30% of moringa oleifera branch and trunk powder, 5%-20% of moringa oleifera seed powder, 5%-30% of potato skin powder and the balance zeolite powder. Chitosan, moringa oleifera branches and trunks, moringa oleifera seeds and zeolite powder have the water purifying effect, organic matter ingredients of a flocculating system are enhanced through potato skin, the flocculating agent can react with animal husbandry sewage with complex ingredients to generate large-particle flocculating precipitate, flocculating efficiency is improved, the flocculating precipitation effect is remarkable, the water purifying effect is remarkable, the flocculating precipitate can be degraded, cost is low, and no secondary pollution is caused.
