Preparation method of bactericide capable of purifying water

Abstract

The invention discloses a preparation method of a bactericide capable of purifying water. The preparation method comprises the following steps: preparing a Chinese herbal preparation from raw Chineseherbs by microwave extraction, alcohol precipitation and decolorization, mixing with dibromohydantoin, dried alum, sulfur suspension and bamboo vinegar uniformly, adding a binder, stirring uniformly,then granulating and drying to obtain the bactericide, wherein the binder contains bentonite, sodium paraben and D-mannose. The preparation method of the bactericide capable of purifying water is simple, easy, readily available in raw materials, high in yield and raw material utilization, high in production efficiency, fast in granulation and low in production energy consumption; and the preparedbactericide has broad-spectrum bactericidal and bacteriostatic activity and good granule stability, and can quickly achieve the purposes of sterilization, water purification and water fertilization.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a preparation method of a fungicide capable of purifying water. technical background [0002] With the rapid development of aquaculture in my country, the proportion of aquaculture in the aquaculture industry is increasing continuously. Due to the continuous expansion of market demand, the breeding density of aquaculture farmers is also increasing. The increase in breeding density has accelerated the cycle of water quality aging and water quality deterioration. The first is the pollution of the aquaculture water environment: Due to the abuse of clear pond disinfectants, insecticides, random sewage discharge at the bottom of high ponds, and biological pollution of offshore red tides, some water quality problems in the seawater included in the aquaculture pond or the surface well water extracted in recent years have been affected. Indicators such as beneficial microorganisms, algae spec...

Increased breeding density speeds up the cycle of water quality aging and water quality deterioration

The first is the pollution of the aquaculture water environment: Due to the abuse of clear pond disinfectants, insecticides, random sewage discharge at the bottom of high ponds, and biological pollution of offshore red tides, some water quality problems in the seawater included in the aquaculture pond or the surface well water extracted in recent years have been affected. Indicators such as beneficial microorganisms, algae species, water hardness and alkalinity, and heavy metal indicators are increasingly unsuitable for the growth of algae. It is difficult for beneficial algae to reproduce as a population advantage, resulting in difficulties in fertilization and water.

The second is the aging and acidification of the bottom of old earth ponds: After nearly ten years of development and breeding, most of the bottoms of earth ponds have been seriously acidified, the bottom mud is highly viscous, acidic, hardened, and the exchange of sediment nutrients and water energy and substances stagnates, resulting in algae It is difficult to continuously absorb balanced nutrients, resulting in unstable algae phase, easy to clear water, moss on the bottom of the pool, and the reverse side of the mud skin, etc.

Third, there is a mixed bag of fertilizer and aquatic products in the market. There is no clear industry production and use standards, and no clear ideas for product promotion and use; The fertilizer and water given to shrimp by compound fertilizer is the cause of the imbalance of algae and bacteria, and the difficulty of cultivating beneficial algae into dominant populations
