Problems solved by technology

[0003] Compared with industrial wastewater or domestic sewage, mariculture wastewater has the characteristics of low content of potential pollutants and large water volume, and due to the salinity effect of seawater and the particularity of the pollution structure of mariculture wastewater, the treatment of aquaculture wastewater is more difficult. , when the conventional method is applied to mariculture wastewater, there are problems such as long time-consuming, high energy consumption and high cost, and the concentration of ammonia nitrogen after treatment still does not meet the requirements.

Abstract

The invention discloses a wastewater treatment device and technology for mariculture. The device comprises a mixing unit, a microwave flocculation unit and a solid-liquid separation unit. The mixing unit is used for mixing mariculture wastewater with an agent for obtaining a mixed solution; the microwave flocculation unit is used for making contaminant in the mixed solution receive microwaves forgenerating floccule sediment; the solid-liquid separation unit is used for separating floccule in the mixed solution from water. According to the wastewater treatment device and technology for mariculture, after a flocculant is mixed with the mariculture wastewater in the mixing unit, the mixed solution enters the microwave flocculation unit, and under the effect of microwaves, a sludge structureis subjected to destabilization and sufficient flocculation in a short time. Then the mixed solution enters the solid-liquid separation unit, and under the laminar condition, sludge in the wastewateris precipitated on an inclined plate. The whole device is low in cost and small in occupation floor, and continuous treatment of the mariculture wastewater is achieved.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment, and in particular relates to a device and process for treating wastewater from marine aquaculture. Background technique [0002] Aquaculture wastewater in marine aquaculture mainly includes pollutants such as feces, residual bait, and dead bodies produced by aquatic products during the aquaculture process. These pollutants are rich in ammonia nitrogen. Ammonia nitrogen can affect the normal growth and metabolism of aquatic products, so for aquaculture seawater, ammonia nitrogen concentration is one of the main control indicators. At first, farmers adopted the method of discharging the aquaculture wastewater with poor water quality into the sea and then injecting it into the fresh water body to ensure the water quality and meet the growth requirements of aquatic products. However, in recent years, with the rapid development of high-density artificial aquaculture and the increasing po...
