<p>The wastewater treatment agent with oxidative effect for drainage area with limited or non-existing supply of atmospheric oxygen, consists of inorganic nitrates, iron salts and/or aluminum chloride, polyaluminum chloride and/or aluminum nitrate. The nitrates of sodium, potassium, magnesium, aluminum, iron and/or calcium and iron chloride, iron sulfate and/or iron nitrate are contained in the agent. The inorganic salt is present in a common solution, where iron-ions are contained in the presence of nitrates. The wastewater treatment agent with oxidative effect for drainage area with limited or non-existing supply of atmospheric oxygen, consists of inorganic nitrates, iron salts and/or aluminum chloride, polyaluminum chloride and/or aluminum nitrate. The nitrates of sodium, potassium, magnesium, aluminum, iron and/or calcium and iron chloride, iron sulfate and/or iron nitrate are contained in the agent. The inorganic salt is present in a common solution, where iron-ions are contained in the presence of nitrates. The common solution consists of 43-46 mass.% of calcium nitrate, 10-15 mass% of iron-III-chloride or iron-III-nitrate and 5-8 mass% of polyaluminum chloride or aluminum nitrate. The total solid materials in the solution are 60%. An independent claim is included for a method for the treatment of wastewater in drainage area.</p> |
