A natural ingredient farm sewage flocculant

Abstract

The invention relates to a natural ingredient farm sewage flocculant which is composed of, by weight, 3-15% of chitosan, 10-30% of eucalyptus leaf powder, 5-20% of eucalyptus fruit powder, 5-30% of potato peel powder and the balance of zeolite powder. Chitosan, eucalyptus leaves, eucalyptus fruits and the zeolite powder have water purifying efficacy, and potato peel improves organic matter ingredients of a flocculation system, so that the flocculant can react with animal husbandry sewage complex ingredient to generate large-particle flocculation precipitate, flocculation efficiency is improved, flocculation and precipitation effect is remarkable, water purifying effect is remarkable, the flocculation precipitate is degradable, cost is low, and no secondary pollution is caused.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and in particular relates to a natural ingredient farm sewage flocculant. Background technique [0002] Sewage from animal husbandry farms is the main source of pollution to the surrounding environment by livestock farms. Large farms are very polluted, 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 includes...

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
