Embodiment Construction

[0032] Cannery wastewater pretreatment method: Cannery wastewater needs to be pretreated before it is used for algae cultivation. The method is: first filter the wastewater with a 60-mesh sieve to remove floating objects, glass slag, hair, silt, leaves, plastic bags, etc. For larger solids, the sewage is introduced into the cement aeration tank with a length of 30 meters, a width of 20 meters and a depth of 0.7 meters. The pool is oriented east-west to receive more sunlight; the water depth is kept at 60 cm; Add 50 grams of quicklime to the sewage and evenly sprinkle quicklime (it is best to add 1 kg of quicklime to 5 liters of pure water in advance, dissolve, dilute, stir in a plastic bucket, and then sprinkle the whole pool), every 60 minutes. Add 80 grams of rice sewage to the whole pond and sprinkle alum (alum is preferably dissolved in a plastic bucket in the amount of 100 grams plus 4 liters of pure water in advance, diluted and stirred evenly, and then sprinkled in the w...

Abstract

The invention discloses a culture medium and a culture method for culturing amphora ovalis by using wastewater in a canning plant, and the culture medium and the culture method can be used for treating the wastewater in the canning plant with low cost, utilizing wastes and obtaining microalgae with important bait value. The amphora ovalis traditionally cultured by adopting a Liao's improved culture solution and an open runway pool is slow in growth, low in yield, easy to contaminate and low in benefit, whereas aerated culture with transparent 1.5cm<3> cylindrical food-grade plastic drums is capable of realizing low cost and quick growth, avoiding pollution contamination and is easy to operate; the wastewater in the canning plant, sodium silicate, ammonium ferric citrate, ammonium molybdate, potassium chromate, fish meal, sodium carboxymethyl cellulose, L-arginine, potassium dihydrogen phosphate, medical stone meal, 920-type plant growth substance, vitamin S-3 solution, M-F trace element solution, sodium thioglycollate and the like are added in the culture medium, namely organic fertilizers and inorganic fertilizers are used together, so that the nutrition is more comprehensive and balanced, the growth rate of the amphora ovalis is greatly improved, and the yield is improved by 420%.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a medium and a cultivation method for cultivating Amphica ellipsoides by using waste water from a cannery. Background technique [0002] The cannery discharges a large amount of wastewater every year, which contains high concentrations of sugar, organic acids, pectin, acids, alkalis and other organic substances. If it is directly discharged into rivers, rivers, lakes, and reservoirs without treatment, it will consume a large amount of dissolved oxygen and cause water shortages. Oxygen kills fish and other aquatic organisms. With the rapid development of the canned food industry, the problem of wastewater treatment has increasingly attracted people's attention. [0003] The cannery mainly has four major categories of products, fruits, vegetables, meat, and aquatic products. The quality and quantity of the wastewater discharged by the four products are very different. The w...
