Problems solved by technology

[0004] Technical problem to be solved: This application mainly proposes a resource utilization method of aquaculture waste, which solves the waste of water resources caused by the water-changing aquaculture mode existing in the prior art, and the accumulation of a large amount of ammonia nitrogen in the bottom mud tends to accelerate the deterioration of water quality. Technical problems such as time-consuming and labor-intensive effects are not good

Embodiment 1

[0025] A method for resource utilization of aquaculture waste, comprising the steps of:

[0026] Step 1: Use microporous aerator BioMat and air-driven hydraulic stirring AirLD to ensure that the dissolved oxygen in the water body is high in dissolved oxygen at 4.5-5.5 mg / L and water circulation, use sucrose as the carbon source, adjust the carbon-nitrogen ratio C / N to 15, and cultivate Basic biofloc aquaculture water suitable for the growth of aquaculture animals;

[0027] Step 2: Purchase commercial bacillus on the market such as Nanhua Qianmu compound bacillus powder, soak in 10kg of normal temperature water for 4 hours according to the dose per 500g to obtain the bacterial liquid, and feed it into the water body every week to promote the water body. PHB generation in;

[0028] Step 3: Conduct a 30-day breeding experiment. The experiment is divided into a control group and an experimental group. Each group has 3 indoor cement pools of 3.0 m × 1.0 m × 0.8 m, with an average ...

Abstract

The invention discloses a resource utilization method of aquaculture waste. A microporous aerator BioMat and an air-pushed hydraulic stirring shore circulating water pump AirLD are adopted to ensure high dissolved oxygen of 5 mg / L and water circulation of a water body, sucrose is used as a carbon source, the carbon-nitrogen ratio C / N is regulated to be 15, and a basic biofloc culture water body suitable for growth of cultured animals is cultured; commercialized bacillus South Ranch compound bacillus raw powder on the market is purchased, the bacillus South Ranch compound bacillus raw powder issoaked in 10 kg of normal-temperature water for 4 h according to the dosage for per 500 g and then splashed to a whole pond, the available water surface is 20 mu, the bacillus South Ranch compound bacillus raw powder is fed into a water body every week, and production of PHB in the water body is promoted.

Description

technical field [0001] The invention belongs to the field of environmental technology, in particular to a resource utilization method of aquaculture waste. Background technique [0002] my country's aquaculture industry is developing rapidly. Although there are many restrictions on quality, disease and safety risks, the pursuit of profit and resource pressure make farmers always pursue high yields. However, high-density farming for the purpose of high yield will inevitably lead to high feed consumption, high water pollution and high discharge to the environment, and the continuous farming of the water body will also cause an overload of waste nitrogen. The aquaculture industry is facing many limitations and bottlenecks. Traditional aquaculture techniques such as watching water to raise fish and relying on algae to control water quality are far from being able to adapt and meet the reality of industrial development. [0003] The removal of ammonia nitrogen in the traditional...
