Embodiment 1
[0040] A covering material for slow-flowing shallow water channels with black and odorous bottom mud, which is made of the following raw materials in mass fraction:
[0041]
[0042] A preparation method of a black and odorous water restoration agent, the steps are:
[0043] 1) Soak the clay minerals in dilute hydrochloric acid with a mass fraction of 1 or 2 or 3 or 4 or 5% for 1 or 2 hours, then wash with water until neutral (pH=6.5 or 6.8 or 7 or 7.4 or 7.7 or 8), Place in a muffle furnace and bake at 200 or 220 or 240 or 260 or 280 or 300°C for 1 or 2 hours, and set aside;
[0044] 2) Mix heavy calcium carbonate, light calcium carbonate, modified clay mineral material, oxygenator and flocculant according to the above mass fractions to prepare a black and odorous water restoration agent;
[0045] Described clay mineral is montmorillonite;
[0046] The oxygen increasing agent is percarbamide;
[0047] The flocculant is polyferric chloride.
[0048] Through the above te...
