A device for deodorizing and harmless treatment of feces, its automatic control system and treatment method

Abstract

The invention provides equipment for deodorization and harmless treatment of excrement, an automatic control system and a treatment method of the equipment. The equipment adopts potassium alum or polyaluminium chloride for excrement treatment. pH of feces liquid is monitored, and a signal is transmitted to a microprocessor which controls the opening and closing of a solenoid valve switch, so as to control the amount of potassium alum, polyaluminium chloride, polymerization ferric chloride or poly ferric sulfate and water to be added and ensure that excrement treatment is completed. Moreover, the microprocessor controls the solenoid valve at a discharge hole which is opened for discharge of treated excrement. The equipment realizes fully automated harmless treatment process without manual control.

Description

technical field [0001] The invention relates to the field of feces harmless treatment, in particular to equipment for deodorizing and harmless treatment of feces, an automatic control system and a treatment method thereof. Background technique [0002] With the rapid development of my country's pig industry and the continuous expansion of the scale of pig herds, the discharge of pig manure and urine is also increasing sharply. If a large amount of pig manure and urine wastewater is not treated properly, the water quality will be affected. Because pig manure and urine contain a large amount of Organic matter and organisms will consume dissolved oxygen in water during decomposition, thereby destroying the ecological balance. For example, when the source of tap water is polluted by pig feces and urine wastewater, the water will contain odor, which will affect people's drinking; second, it will hinder environmental sanitation, because Pig manure will emit a pungent odor, and it is...

[0002] With the rapid development of my country's pig industry and the continuous expansion of the scale of pig herds, the discharge of pig manure and urine is also increasing sharply. If a large amount of pig manure and urine wastewater is not treated properly, the water quality will be affected. Because pig manure and urine contain a large amount of Organic matter and organisms will consume dissolved oxygen in water during decomposition, thereby destroying the ecological balance. For example, when the source of tap water is polluted by pig feces and urine wastewater, the water will contain odor, which will affect people's drinking; second, it will hinder environmental sanitation, because Pig manure will emit a pungent odor, and it is easy to breed mosquitoes and flies, which seriously affects the quality of living environment in neighboring communities and is harmful to health. , if it is not treated and directly used for crop irrigation or directly discharged into rivers, there is a great potential for disease transmission
