Embodiment 1

[0012] ① Filtration: Use a 200-mesh filter to remove large impurities in the spirulina wastewater, and then use a 360-mesh filter to remove small impurities;

[0013] ②Determination of dissolved oxygen: Measure the dissolved oxygen of the spirulina wastewater at 8 o'clock in the morning, and the measured dissolved oxygen is less than 8g / L;

[0014] ③Chemical treatment: Spirulina wastewater enters the treatment pool, and the water level in the treatment pool is 1-2 meters. Under dark conditions, add bleaching essence, stir evenly, and make the available chlorine concentration 0.08g / L, let stand for 18 hours, and then stir until The concentration of available chlorine is 0.0005g / L, and the bottom water is discarded after standing for 2 hours;

[0015] ④Adjust the pH value: adjust the pH value of the culture medium to 10 with sodium bicarbonate for the chemically treated spirulina wastewater;

[0016] ⑤Adjust the amount of nitrogen: use a mixture of sodium nitrate and ammonium b...

Embodiment 2

[0018] ① Filtration: Use a 200-mesh filter to remove large impurities in the spirulina wastewater, and then use a 360-mesh filter to remove small impurities;

[0019] ② Determination of dissolved oxygen: Measure the dissolved oxygen of the spirulina wastewater at 7:30 in the morning, and the measured dissolved oxygen is greater than 8g / L;

[0020] ③Adjust the pH value: use sodium bicarbonate to adjust the pH value of the medium to 9.9 in the spirulina wastewater;

[0021] ④Adjust the amount of nitrogen: use a mixture of sodium nitrate and ammonium bicarbonate in a mass ratio of 10:1 to adjust the pH value of the spirulina wastewater, and adjust the nitrogen content of the medium to 1g / L, so that the medium can be inoculated with spirulina , continue to be used in Spirulina cultivation.

Abstract

The invention provides an overwintering, rejuvenation and conservation culture medium for culturing spiral seaweed, which comprises a nutritional carbon source, nutritional nitrogen sources, nutritional phosphorus and potassium, mineral nutrition, vitamins, oligosaccharide and a complexing agent. The overwintering, rejuvenation and conservation culture medium for culturing the spiral seaweed is characterized in that sodium bicarbonate is used as the carbon source, and the concentration of the sodium bicarbonate is 500g-1000g per cubic meter of culture solution; sodium nitrate and urea are used as the nitrogen sources, and the concentrations of the sodium nitrate and the urea are 50g-150g per cubic meter of culture solution and 50g-100g per cubic meter of culture solution respectively; monopotassium phosphate is used as the nutritional phosphorus and potassium, and the concentration of the monopotassium phosphate is 50g-100g per cubic meter of culture solution; ferric chloride and manganese chloride are used as the mineral nutrition, and the concentrations of the ferric chloride and the manganese chloride are 10g-30g per cubic meter of culture solution and 1g-3g per cubic meter of culture solution respectively; the concentrations of the vitamins B1 and B2 are 0.05g-0.15g per cubic meter of culture solution respectively; and the concentrations of the oligosaccharide and the ethylene diamine tetraacetic acid-disodium (EDTA-2Na) complexing agent are 10g-20g per cubic meter of culture solution respectively. The spiral seaweed cultured by the method provided by the invention is capable of safety overwinter under the natural conditions in winter and is capable of increasing rejuvenation rate.

Description

Technical field: [0001] The invention relates to a method for recycling spirulina medium. Background technique: [0002] Spirulina is a natural health food rich in protein and mineral nutrition. Spirulina is cultured in a culture solution composed of nutrient carbon source, nutrient nitrogen source, nutrient phosphorus and potassium, mineral nutrition, vitamins, oligosaccharides, complexing agent, etc. under appropriate conditions. After the spirulina is harvested, the culture fluid becomes waste water. Some small-scale production enterprises simply treat it as agricultural irrigation water, and some even discharge it directly, which not only causes environmental pollution, but also causes waste of production raw materials. In order to deal with the spirulina culture wastewater, the treatment method similar to that of chemical industry and domestic wastewater is mainly adopted at present, as the publication (announcement) number is CN1903751, and the invention patent appli...
