specific Embodiment approach 1

[0019] Specific embodiment one: this embodiment is the biological flocculation water quality control agent that can reduce the ammonia nitrogen of the freshwater pond by mass parts by 35~45 parts of cornstarch, 35~45 parts of glucose, 10~20 parts of montmorillonite and 0.03~0.08 parts EM bacteria mixed.

[0020] The beneficial effects of this embodiment are: the biofloc water quality regulator that can reduce ammonia nitrogen in freshwater ponds in this embodiment is a composite water quality regulator of carbon source and microecological preparations to reduce the levels of ammonia nitrogen and nitrite nitrogen in aquaculture ponds. The composite water quality regulator is composed of simple carbohydrate glucose, complex carbohydrate starch, montmorillonite and EM bacteria.

[0021] ①Glucose can be quickly utilized, and the response is fast;

[0022] ②Starch needs to be decomposed into small molecules by microorganisms before it can be used, stable and long-lasting;

[0023...

specific Embodiment approach 2

[0029] Specific embodiment two: The difference between this embodiment and specific embodiment one is: the biofloc water quality regulator that can reduce ammonia nitrogen in freshwater ponds consists of 42 parts of cornstarch, 42 parts of glucose, and 15.95 parts of Mongolian Destoned and 0.05 parts of EM bacteria mixed. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0030] Specific implementation mode three: a method for adding a biofloc water quality regulator that can reduce ammonia nitrogen in freshwater ponds described in this implementation mode is carried out in the following steps:

[0031] When the ammonia nitrogen content in the freshwater pond is 3mg / L~6mg / L, the dosage of the biofloc water quality regulator that can reduce the ammonia nitrogen in the freshwater pond is 10~15kg / mu·m. The dissolved oxygen content is not less than 4mg / L.

[0032] The dosage of the bio-floc water quality regulator that can reduce ammonia nitrogen in freshwater ponds described in this embodiment is 10-15 kg / mu·meter. Depth of freshwater pond.

[0033] The biofloc water quality control agent capable of reducing ammonia nitrogen in freshwater ponds in this embodiment can quickly and permanently produce biofloc and reduce the levels of ammonia nitrogen and nitrite nitrogen in water bodies through the combination of several substances.

Abstract

The invention provides a biofloc water quality regulating agent capable of reducing the ammonia nitrogen of a freshwater pool and an addition method of the biofloc water quality regulating agent, and relates to a pool water quality regulating agent and an addition method thereof. The biofloc water quality regulating agent is used for solving the problems of waste of water resources and pollution on surroundings due to the existing method of injecting new water to reduce the content of ammonia nitrogen in the freshwater pool, and the problem of limited ammonia nitrogen reduction action of independently added microecologics. The water quality regulating agent is prepared by mixing corn starch, glucose, montmorillonite and EM bacteria. The addition method comprises adding the biofloc water quality regulating agent capable of reducing the ammonia nitrogen of the freshwater pool by the dosage of 10-15kg / mu.m when the ammonia nitrogen content in the freshwater pool ranges from 3mg / L to 6mg / L.

Description

technical field [0001] The invention relates to a pond water quality regulating agent and an adding method thereof. Background technique [0002] With the development of large-scale and intensive aquaculture in our country, in the process of aquaculture, the problem of high ammonia nitrogen in the pond is often encountered, mainly due to the aging of the pond, excessive feeding of feed and abuse of fish medicine. This problem is exacerbated in culture ponds. At present, the ammonia nitrogen level in ponds is mainly reduced by adding new water and adding probiotics. Adding new water wastes a lot of water resources and pollutes the surrounding environment, which is contrary to the sustainable development of aquaculture. Under the condition of high ammonia nitrogen, the carbon source in the pond is insufficient, and the effect of adding probiotics alone to reduce ammonia nitrogen is limited. Contents of the invention [0003] The present invention aims to solve the existing...
