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...

Abstract

The invention discloses a black and odorous water body restoration agent as well as a preparation method and application thereof. The black and odorous water body restoration agent is prepared from heavy calcium carbonate, light calcium carbonate, modified clay mineral materials, oxygenating agents and flocculants according to a certain proportion. The preparation method comprises the steps that 1, the heavy calcium carbonate, the light calcium carbonate, the modified clay mineral materials, the oxygenating agents and the flocculants are mixed according to a certain proportion; an ecological restoration agent is prepared; 2, the ecological restoration agent is uniformly paved and sprinkled on the water surface of the black and odorous water body into the bottom; (3) after a period of time,aquatic plants are planted in a covering region; the aquatic plants are scientifically managed and maintained. The formula is reasonable; the use is convenient; the cost is low; the environment-friendly effect is achieved; the restoration effect is good; the ecological and environment-friendly effects are achieved; the method is easy to implement; the operation is simple and convenient. The problems that the aquatic plants in a black and odorous bottom mud water body are difficult to survive and grow, and the like are solved; pollutants such as bottom mud organic matters are subjected to in-situ removal, so that the recovery of water ecological environment is facilitated; the recovery and the healthy development of the water ecological system are accelerated.

Description

technical field [0001] The invention belongs to the technical field of water body ecological restoration, and more specifically relates to a black and odorous water body restoration agent, and also relates to a preparation method of a black and odorous water body restoration agent, and also relates to a use of a black and odorous water body restoration agent, a black and odorous water body restoration agent The water restoration agent can be widely used in restoration projects of black and odorous lakes and river courses. Background technique [0002] The black and odorous water body is mainly the result of the imbalance of oxygen supply and oxygen consumption caused by excessive pollution. The self-purification ability of the black and odorous water body is poor. The water body is under anoxic or even anaerobic conditions for a long time. A large number of retained pollutants are transformed and produce ammonia nitrogen, hydrogen sulfide, and Smelly and malodorous substance...
