Problems solved by technology

[0006] The present invention aims at the problem in the prior art that the waste water still does not meet the standard after treatment, and the system will not further process it, but will directly put the treated water that has not reached the standard into use, making it difficult to achieve an ideal breeding environment. It provides a method based on ammonia nitrogen and Aquaculture circulating water treatment system with precise control of dissolved oxygen

Embodiment 1

[0048] Such as figure 1 As shown, the aquaculture circulating water treatment system based on precise control of ammonia nitrogen and dissolved oxygen includes water inlet detection module, parameter analysis module, water outlet detection module, water treatment detection module, water outlet analysis module, treatment analysis module, control management module, execution module, strategy adjustment module, program update module, storage module and early warning module.

[0049] Among them, the water inlet detection module and parameter analysis module are integrated on the water inlet perception subsystem; the water outlet detection module, water treatment detection module and outlet water analysis module are integrated on the outlet water perception subsystem; the processing analysis module, control management module, and strategy adjustment module , program update module, storage module and early warning module are integrated on the intelligent management subsystem; the ex...

Embodiment 2

[0068] Different from Embodiment 1, this embodiment also includes an impurity detection unit and an execution controller, and the impurity detection unit is used to detect the impurity concentration on the surface of the culture pond; in this embodiment, the water inlet pipe and the water outlet pipe are located opposite to each other in the culture pond. On both sides, the water inlet pipe is divided into M pieces from top to bottom, and the water outlet pipe is also divided into M pieces from top to bottom. Each water inlet pipe and each water outlet pipe are respectively electrically connected to the execution controller, and the impurity detection unit is connected to the execution control unit. The electrical connection of the device; the executive controller is used to control the water inlet speed of the water inlet pipe, and is also used to control the water outlet speed of the water outlet pipe.

[0069] During the water change process, when the detection data fed back...

Abstract

The invention belongs to the technical field of aquaculture circulating water treatment, and particularly relates to an aquaculture circulating water treatment system based on precise control of ammonia nitrogen and dissolved oxygen. The system comprises a water inlet detection module for detecting the quality of inlet water, a processing analysis module for generating a preliminary processing scheme, a control management module for generating a control signal according to the preliminary processing scheme, an execution module for performing water quality treatment according to the control signal, an effluent detection module for detecting the quality of effluent, a water treatment detection module for analyzing the water quality of the effluent, a strategy adjustment module for generatingan adjustment control strategy when the analysis result of the water treatment detection module does not meet the water outlet standard, and a scheme updating module for generating a new processing scheme. The control management module is also used for updating the control signal according to the new processing scheme. By using the system, the quality of water entering the culture area can be ensured.

Description

technical field [0001] The invention belongs to the technical field of aquaculture circulating water treatment, and in particular relates to an aquaculture circulating water treatment system based on precise control of ammonia nitrogen and dissolved oxygen. Background technique [0002] Circulating aquaculture is a new type of aquaculture model that is currently being vigorously developed and promoted in my country. This model uses a series of water treatment mechanisms, such as sludge return cleaning mechanism, DO (dissolved oxygen) mechanism, ammonia nitrogen treatment mechanism and water outlet mechanism, etc. to aquaculture. After the wastewater generated in the pool is treated, it is recycled again. [0003] Through recirculating aquaculture, the current aquaculture, especially the water pollution problem of marine aquaculture in the offshore field has been greatly improved, and the pollution caused by the discharge of aquaculture wastewater to the surrounding environmen...
