Abstract
The invention discloses a treatment process and device for polyculture fishpond waste water, and belongs to the field of waste water treatment technologies. The treatment process includes the steps that the discharged waste water passes through a grating so that weeds and other substances can be removed, then enters a water collecting pond to be collected, sequentially passes through a first chemical adding barrel, a second chemical adding barrel, an aeration tank, a settling pond and a sand filtering pond and enters a recycling water pond after filtering, the water in the recycling water pond is purified through a secondary circulation purification device in a secondary mode, and therefore purified water capable of being recycled is obtained. According to the treatment process, the waste water passes through algae and others inside the first chemical adding barrel so as to be self-purified, then passes through biological activated water treating agents inside the second chemical adding barrel and sequentially passes through a microwave treatment device, the aeration tank, the settling pond and the sand filtering pond to be treated, and in this way, the clean water is obtained and conveyed back to the recycling water pond; the secondary circulation purification device is arranged inside the recycling water pond, through adsorbing of activated carbon inside the activated carbon filtering pond and treatment of a fine filter and a reverse osmosis pond, the treatment effect is good, the good water treatment effect can be guaranteed, the quality of the discharged water is stable, and finally the water body meets the requirements of aquaculture.
