Embodiment 1

[0028] In the present embodiment, the method for purifying polluted water into water for aquaculture comprises the following steps:

[0029] (1) After draining the remaining water in the pond, dig out the silt at the bottom of the pond, and dry-sprinkle bleaching powder on the bottom of the pond where the silt has been dug out (the dry-sprinkling amount of bleaching powder is 20 catties / mu), and then dry the bottom of the pond for 25 days;

[0030] (2) After drying the bottom of the pond, the pond is filled with water to a water depth of 80 cm; and on the day of water intake, copper-iron mixture is sprayed into the pool water. The amount of copper-iron mixture is 1.34 catties / mu of copper sulfate and 0.5 catties / mu;

[0031] (3) On the second day after entering the water, sprinkle sodium trichloroisocyanurate into the pool water to kill pathogenic bacteria in the pool water. The amount of sodium trichloroisocyanurate splashed is 2 catties / mu;

[0032] On the third day after en...

Embodiment 2

[0045] In the present embodiment, the method for purifying polluted water into water for aquaculture comprises the following steps:

[0046] (1) After draining the remaining water in the pond, dig out the silt at the bottom of the pond, and dry-sprinkle bleaching powder on the bottom of the pond where the silt has been dug out (the dry-sprinkling amount of bleaching powder is 20 catties / mu), and then dry the bottom of the pond for 25 days;

[0047] (2) After drying the bottom of the pond, the pond is filled with water to a water depth of 90 cm; and on the day of water intake, copper-iron mixture is sprayed into the pool water. The amount of copper-iron mixture is 1.4 catties / mu of copper sulfate and 0.52 catties / mu;

[0048] (3) On the second day after entering the water, sprinkle sodium trichloroisocyanurate into the pool water to kill pathogenic bacteria in the pool water. The amount of sodium trichloroisocyanurate splashed is 2.5 catties / mu;

[0049] On the third day after ...

Abstract

The invention relates to a method for purifying polluted water into aquaculture water. The method comprises the steps of: (1) draining water left in a pond, digging out sludge at the bottom of the pond, scattering bleaching powder to the bottom of the pond, and then drying the bottom of the pond in the sun; (2) after the bottom of the pond is dried in the sun, enabling water to enter the pond until the water depth is 80 to 100 cm; on the day of water inflow, applying copper-iron mixture to the water in the pond; (3) splashing sodium trichloroisocyanurate into the water in the pond on the second day after the water enters the pond; (4) spraying brofenvalerate into the water in the pond on the seventh day after the water enters the pond; (5) sprinkling EDTA into the water in the pond on the tenth day after the water enters the pond; (6) starting a waterwheel type aerator to stir water in the pond in the fourteenth day after the water enters the pond, and splashing fermented tea seed cakes into the water in the pond; and (7) observing the pond water on the eighteenth day after the water enters, and if copepoda zooplankton exists in the pond water, finishing the water treatment. According to the invention, water which is severely polluted can be purified and treated into aquaculture water, so that water can be taken from a polluted river nearby, and the water demand of aquaculture industry is met.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a method for purifying polluted water into water for aquaculture. Background technique [0002] Due to the substandard discharge of industrial sewage and domestic wastewater along the river, some rivers are seriously polluted. The Lianjiang River Basin where the applicant is located has been seriously polluted and the water quality is poor in recent years, making it difficult to obtain sufficient water sources for aquaculture, which seriously restricts the normal development and development of aquaculture on both sides of the Lianjiang River , Therefore, how to provide sufficient aquaculture water for the aquaculture industry has become an urgent problem to be solved. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for purifying polluted water into water for aquaculture, which can purify and treat se...
