Environment-friendly sewage purifying method

Abstract

The invention discloses an environment-friendly sewage purification method, which comprises a box body, a first partition board and a second partition board are arranged in sequence from top to bottom inside the box body, and the inside of the box body is located at the lower layer of the second partition board A sewage bin is provided, and a disinfectant liquid bin is arranged inside the box and on the left side of the upper upper layer of the first partition. The lower right corner of the disinfectant liquid bin is connected with a discharge pipe, and the left end of the discharge pipe runs through the disinfectant liquid bin The right wall extends to the bottom of the disinfectant tank. The invention relates to the technical field of sewage treatment. The environmentally friendly sewage purification device can completely suck out the disinfectant and coagulant by setting a certain inclination to the bottom of the disinfectant tank and the coagulant aid, reducing waste, using the disinfectant to disinfect the sewage, and using the auxiliary The coagulant accelerates the adsorption of toxic particles such as heavy metals. The combined use of disinfectant and coagulant aid not only enhances the disinfection ability, but also shortens the precipitation time of particles and improves the purification efficiency.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an environment-friendly sewage purification method. Background technique [0002] 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. Acids, alkalis, oxidants, and compounds such as copper, cadmium, mercury, and arsenic in sewage, organic poisons such as benzene, dichloroethane, and ethylene glycol, will poison aquatic organisms to death, affect drinking water sources, scenic spots, and sewage When the organic matter in the water is decomposed by microorganisms, the oxygen in the water is consumed, which affects the life of aquatic organisms. After the dissolved oxygen in the water is exhausted, the organic matter undergoes ana...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides an environmentally friendly sewage purification method, which solves the problem of manual spraying of disinfectant, uneven mixing of disinfectant and sewage, and incomplete disinfection. Some sewage purification measures use a separate water pump to spray disinfectant, Waste of energy, moreover, it takes too long to settle and settle, and the removal of particles such as heavy metals is not complete
