Embodiment 1

[0027] A flocculant preparation process for aquaculture sewage treatment:

[0028] Step 1: According to the formula, it consists of the following mass components: 11% polysilicate iron (PSF), 11.5% methacrylic acid, 6% chlorate, 3.5% silane coupling agent, 9.5% polydimethyl Diallyl ammonium chloride, 7% cellulose, 25% polyferric chloride (PFC), 5% coagulant, 7% chitosan, 2.5% medium molecular weight polyacrylamide and 12% Aspergillus sojae, The sum of the above components is 100%. First take 11% polysilicate ferric silicate (PSF), 11.5% methacrylic acid, 6% chlorate and 25% polyferric chloride (PFC) and add them into the reaction kettle for airtight mixing, and use 800r / min stirring equipment for mixing. Stir for 2 minutes, then use ultrasonic vibration for 5 minutes, the ultrasonic frequency during ultrasonic vibration is 25kHz, then seal and react in the reactor for 2 hours, the oxygen content in the air in the sealer is the oxygen content in the normal atmosphere.

Abstract

The invention relates to a formula and a preparation process thereof and in particular relates to a flocculant formula for treating sewage in a breeding industry and a preparation process of the flocculant formula. The invention aims to provide the flocculant formula with the characteristics of environmental protection, good use effect and low dosage for treating sewage in the breeding industry and the preparation process of the flocculant formula. The flocculant formula for treating the sewage in the breeding industry is prepared from the following components in percentage by mass: 8 to 13 percent of polysilicate ferrite (PSF), 10 to 15 percent of methacrylic acid, 2 to 8 percent of chlorate, 1 to 6 percent of silane coupling agent and the like. The preparation process comprises five steps. According to the flocculant formula disclosed by the invention, the effects of facilitation for environmental protection, good use effect and low dosage are realized; the flocculant is low in dosage and has good flocculation effect; the method is simple, easy to operate and cost-saving; in addition, colloidal particles can be strongly adsorbed; the condensation can be achieved by adsorbing, bridging and cross-linking effects.

Description

technical field [0001] The invention relates to a formula and a preparation process thereof, in particular to a flocculant formula and a preparation process thereof for aquaculture sewage treatment. Background technique [0002] Breeding is the use of livestock and poultry and other animals that have been domesticated by humans, or the physiological functions of wild animals such as deer, musk deer, fox, mink, otter, quail, etc., through artificial feeding and breeding, so that they can transform plants such as pasture and feed into Animals can obtain livestock products such as meat, eggs, milk, wool, cashmere, hides, silk and medicinal materials. [0003] Sewage, usually refers to certain polluted discharge water from domestic and production. Sewage mainly includes domestic sewage, industrial wastewater and initial rainwater. The main pollutants of sewage are pathogenic pollutants, oxygen-consuming pollutants, plant nutrients and toxic pollutants. [0004] The flocculant...
