Embodiment 1

[0023] (1) Add 10 parts of lignocellulose and 0.5 parts of asbestos wool to 30 parts of 80-100 mesh wheat straw dry powder, heat to 110-120 °C and mix for 10 minutes, then add 1 part of polyvinyl alcohol resin and 1 part of polystyrene Methyldiallyl ammonium chloride, continue to insulate and mix for 10min to obtain material I;

[0024] (2) Add 2 parts of polyethylene oxide and 2 parts of squash gum to 4 parts of pregelatinized starch, heat to 80-90°C and mix for 15 minutes, then cool in an ice-water bath at a rate of 10-15°C / min , after the temperature drops to 30-35°C, heat-preserve and mix for 30 minutes, then heat again to 100-110°C and heat-preserve and mix for 15 minutes to obtain material II;

[0025] (3) Add material II, 6 parts of acrylic macroporous adsorption resin, 3 parts of dried bean dregs, 3 parts of ceramic micropowder and 2 parts of water-soluble chitosan to material I, and mix well.

[0026] Modification treatment of acrylic macroporous adsorption resin: ad...

Embodiment 2

[0029] (1) Add 10 parts of lignocellulose and 0.5 parts of asbestos wool to 30 parts of 80-100 mesh wheat straw dry powder, heat to 110-120 °C and mix for 15 minutes, then add 2 parts of polyvinyl alcohol resin and 1 part of polystyrene Methyldiallyl ammonium chloride, continue to insulate and mix for 10min to obtain material I;

[0030] (2) Add 2 parts of polyethylene oxide and 2 parts of squash gum to 6 parts of pregelatinized starch, heat to 80-90°C and mix for 15 minutes, then cool in an ice-water bath at a rate of 10-15°C / min , after the temperature drops to 30-35°C, heat-preserve and mix for 15 minutes, then heat again to 100-110°C and heat-preserve and mix for 15 minutes to obtain material II;

[0031] (3) Add material II, 8 parts of acrylic macroporous adsorption resin, 3 parts of dried bean dregs, 3 parts of ceramic micropowder and 2 parts of water-soluble chitosan to material I, and mix well.

[0032] Modification treatment of acrylic macroporous adsorption resin: a...

Embodiment 3

[0035] The precipitants prepared in Examples 1 and 2 of the present invention were used in the same batch of poultry wastewater treatment, and compared with the same amount of commercially available polyacrylamide and polyaluminum chloride, and their treatment effects were measured. The results are shown in Table 1 .

[0036] The waste water treatment effect of precipitant prepared by table 1 embodiment 1 and 2

[0037] project Example 1 Example 2 polyacrylamide PAC Suspended particle removal rate 98％ 97％ 90％ 88％ Ammonia nitrogen organic matter removal rate 85％ 88％ 45％ 32％ Organic phosphorus removal rate 82％ 80％ 18％ 15％

[0038]It can be seen from Table 1 that the primary treatment effect of the precipitants prepared in Examples 1 and 2 of the present invention on poultry wastewater is far superior to that of polyacrylamide and polyaluminum chloride, which are widely used at present, and the removal rate of suspended particles re...

Abstract

The invention discloses a primary precipitator for waste water treatment of livestock breeding, and relates to the technical field of breeding waste water treatment. The primary precipitator is prepared from, by weight, 25-30 parts of wheat straw dry powder, 10-15 parts of lignocellulose, 4-8 parts of pregelatinized starch, 4-8 parts of acrylic acid macroreticular resin, 3-6 parts of dry bean dregs, 3-6 parts of ceramic micro powder, 2-4 parts of polyoxyethylene, 2-4 parts of sesbania gum, 2-4 parts of water-soluble chitosan, 1-2 parts of polyving akohol resin, 1-2 parts of poly dimethyl diallyl ammonium chloride, and 0.5-1 part of asbestos wool. Through the absorption and flocculation, the precipitator can effectively precipitate fine grains in the waste water, ammonia nitrogen, and organic phosphorus matters, and fully play the primary treatment effect, greatly lighten the subsequent treatment difficulty of waste water, and reduce the waste water treatment cost.

Description

[0001] Technical field: [0002] The invention relates to the technical field of aquaculture wastewater treatment, in particular to a primary precipitant for poultry and livestock aquaculture wastewater treatment. [0003] Background technique: [0004] Livestock breeding wastewater mainly comes from poultry manure and cage flushing water. It has the characteristics of deep color, strong odor, high suspended solids, and contains a large number of bacteria, ammonia nitrogen and high organic phosphorus content. If it is directly discharged, it will not only pollute the surface water body , cause eutrophication of water bodies, and also cause damage to groundwater and farmland ecosystems, and even endanger human health. Strict treatment is required before discharge. The treatment methods of livestock breeding wastewater mainly include filtration, interception, sedimentation, physical and chemical adsorption, chemical decomposition, biological oxidation and absorption, etc., and th...
