Embodiment 1
[0032] The present invention specifically degrades the polluted Liaohe Estuary wetland water body, and the water quality is: NH 4 -N concentration up to 35mg / L, NO 2 -N concentration is 12mg / L, NO 3 -The concentration of N is 28mg / L, the concentration of TN is 85mg / L, the concentration of petroleum hydrocarbon is 20mg / L, and the salinity is controlled at 10‰. The shaking treatment is carried out at a temperature of 10°C, including the following steps:
[0033] (1) Preparation of biochar spheres: Weigh 200 g of corn stalks, wash them with deionized water, dry them to constant weight, crush the reed stalks with a plant stalk grinder and pass through a 20-mesh sieve to obtain reed stalk powder. Furnace firing into biochar. The firing conditions of the muffle furnace are: the heating rate is 10°C / min, the temperature is 300°C, and the holding time is 180min; in order to increase the specific surface area of the biochar, that is, to increase the porosity of the biochar and rem...
Embodiment 2
[0041] Sampling a river polluted by ammonia nitrogen and petroleum hydrocarbons, by detecting NH 4 -N concentration up to 5.6mg / L, NO 2 — N concentration is 1.9mg / L, NO 3 — The concentration of N is 3.8mg / L, the concentration of TN is 16.6mg / L, the concentration of petroleum hydrocarbons is 2.1mg / L and the salinity is controlled at 10‰, and the combination of immobilized salt-tolerant and cold-resistant mixed strains is used to degrade ammonia nitrogen and petroleum hydrocarbons. The method is to carry out shaking treatment under the condition of temperature of 15°C, including the following steps:
[0042] (1) Preparation of biochar pellets: Preparation of biochar pellets: Weigh 100 g of reed straw, wash it with deionized water, dry to constant weight, crush the reed straw with a plant straw grinder and pass it through a 20-mesh sieve to obtain Reed straw powder is fired in a muffle furnace to become biochar. The firing conditions of the muffle furnace are: the heating ra...
