Abstract

The invention relates to a mariculture wastewater treatment method and a mariculture wastewater treatment system for a higher-place pond. The mariculture wastewater treatment method for the higher-place pond comprises the following steps: adsorbing shellfish, adsorbing large seaweed, light degradation, and cyclic utilization of a water body. The mariculture wastewater treatment system for the higher-place pond comprises the higher-place pond of which the bottom is connected with a water outlet pipe, two culture troughs are respectively formed in the two sides of the higher-place pond, the higher-place pond is fixedly connected with the culture troughs through an illumination inclined plane, a water inlet pipe is connected onto a trough wall of each culture trough far away from the illumination inclined plane, two baffle plates are arranged in the culture trough, the baffle plate that is near to the water inlet pipe is a water inlet baffle plate, the baffle plate that is far away from the water inlet pipe is a water outlet baffle plate, the water inlet baffle plate is fixedly connected with the trough wall connected with the water inlet pipe, the water outlet baffle plate is fixedly connected with a trough wall at the other end of the culture trough, a gap is reserved between the water outlet baffle plate and the connected trough wall to from a compartment, a trapezoid-shaped mud storage bucket is arranged at the bottom of the culture trough, and a mud discharge pipeline is connected to the bottom of the mud storage bucket.

Description

technical field [0001] The invention relates to a treatment method for marine aquaculture wastewater, in particular to a treatment method and a treatment system for marine aquaculture wastewater in high-level ponds. Background technique [0002] Mariculture has a development history of more than 100 years. In recent years, the demand for seafood has been increasing, and the amount of fishing at sea is no longer enough to meet the demand of the market. As a result, the scale of artificial aquaculture in seawater is becoming larger and larger, and it tends to shift from extensive cultivation to Over-intensive. The problem of pollution has also arisen, and the environment of offshore waters has seriously deteriorated, which has led to an imbalance in the ecosystem of coastal waters. Mariculture wastewater pollution mainly comes from residual feed, excrement from cultured bodies, various chemicals and antibiotics, etc. The main polluting elements are nitrogen, phosphorus and or...
