Animal husbandry sewage flocculating agent with natural ingredients

Abstract

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.

Description

technical field [0001] The invention belongs to the field of sewage treatment, in particular to a flocculant for animal husbandry sewage with natural ingredients. Background technique [0002] Animal husbandry sewage is the main source of animal husbandry farms polluting the surrounding environment. Large farms pollute very seriously, while small farms and even individual farmers, the sewage discharged from them is also the main factor leading to the pollution of the surrounding environment. Animal husbandry sewage mainly includes livestock excrement, pen flushing water, pipe flushing water, waste drinking water, etc. Among them, livestock excrement is the main source of pollution. There have been a lot of research and related products and complete sets of equipment around the treatment of livestock excrement. However, the sewage produced by animal husbandry also includes the flushing water of pens, which contains a large amount of disinfectants and insecticides; it also inc...

AI Technical Summary

Problems solved by technology

At present, there are generally several methods of natural precipitation, inorganic flocculant precipitation, microbial precipitation, and organic flocculant precipitation, but the natural precipitation method is inefficient, and the pollutant index in the discharged sewage is high, which causes great pressure on subsequent treatment; the inorganic flocculant adopts Chemical products are likely to cause more serious secondary pollution to the settled sludge and the upper water body; microbial flocculants are greatly affected by the use environment, and the effect is unstable; organic flocculants are a better way of sedimentation treatment, but the use of Organic flocculants need to be adapted to local conditions. If artificially synthesized organic substances are used, adding them to complex sewage may cause secondary pollution. It is best to use natural organic substances.

Chinese patent 201310481165.0 discloses a flocculant for sewage treatment of animal husbandry farms. Celery leaf powder and dendrobium leaf powder are used to flocculate and precipitate the sewage of animal husbandry farms, and a relatively ideal effect has been achieved. However, dendrobium is a rare and precious species produced in my country. Chinese herbal medicine, this type of plant uses stems as medicine, and originally has relatively few leaves. In commercial breeding, more emphasis is placed on long stems and small and few leaves. Therefore, it is not easy to obtain dendrobium leaf powder; and celery leaf powder is also relatively difficult. Because celery is sold with leaves, and there is no commercial celery leaf or celery leaf powder for sale, the production and promotion of such natural organic flocculants are restricted
