Problems solved by technology

If the agent is highly toxic, it may cause acute poisoning or subacute poisoning, and even cause life-threatening
Although some agents are not acutely toxic, if they are stable in nature and difficult to decompose and disappear after use, they will remain in water, air, crops, agricultural or aquatic products, and animal products, and eventually enter the human body, causing chronic poisoning
At the same time, pesticide pollution can also cause poisoning or even death of other organisms, so as to destroy the ecological balance. Therefore, pesticide residues and pollution must be controlled to reduce the impact and harm on human society

Embodiment

[0026] First, 0.5% by weight of caustic soda is added to the closed biogas slurry tank to promote the fermentation of the biogas slurry. After one year of fermentation, the high-concentration biogas slurry fermentation residue deposited at the bottom is drawn out from the biogas slurry tank, passed into the filter tank and passed through The filter set in the filter tank filters layer by layer to remove impurities in the biogas slurry, and stores the filtered biogas slurry in the liquid storage tank, and then adds 1% by weight of spices into the liquid storage tank to remove foreign matter in the biogas slurry , reduce the stimulation to the user, and use the 2500KW motor rack equipped with dispersing tablets to homogenize the biogas slurry at high speed in the liquid storage tank. After stirring evenly, filter the biogas slurry through a filter, and finally add 0.5% dispersant by weight and stir evenly, and then add 0.6% by weight of curing agent and stir evenly to obtain a fi...

Abstract

The invention discloses a method for preparing a pesticide from biogas slurry, belonging to technical field of pesticide production. The pesticide prepared by the method solves the problem that the pesticide in the prior art can jeopardize people, livestock and the like and pollute the environment. The method comprises the following steps: (1) adding sodium hydroxide, which accounts for 0.3-0.5 wt% of biogas slurry, into the biogas slurry, and fermenting in a closed environment for one year; (2) filtering out impurities to obtain a filtrate; (3) adding fragrance, which accounts for 0.6-1.0 wt% of the filtrate; (4) evenly stirring, and filtering to obtain a mixed liquid; and (5) sequentially adding a dispersant, which accounts for 0.4-0.5 wt% of the mixed liquid, and a curing agent, which accounts for 0.5-0.6 wt% of the mixed liquid, and evenly mixing to obtain the finished product. The invention has the advantages of wide raw material sources, simple manufacturing technique, low energy consumption and low preparation cost.

Description

technical field [0001] The invention belongs to the technical field of pesticide production, and in particular relates to a method for preparing pesticides from biogas slurry. Background technique [0002] At present, pesticides are biologically active chemical substances, most of which are toxic to humans and animals. Usually, people apply pesticides to the natural environment in order to prevent and control the harm of harmful organisms such as pests and weeds. Although the desired purpose is achieved, it also brings pollution problems. If the amount of pesticide residues in the environment and food exceeds the standard, it will have adverse effects on humans, other organisms and even the entire ecosystem. [0003] After pesticides enter the natural ecological environment, they can enter the human body through the respiratory tract, digestive tract, skin and other channels. If the agent is highly toxic, it may cause acute poisoning or subacute poisoning, and even cause l...
