Novel sewage suction purification vehicle

Abstract

The invention discloses a novel sewage suction purification vehicle which includes a vacuum box and a sewage box that are installed on a second-class chassis, wherein a transition hole is formed between the vacuum box and the sewage box, the solid-liquid separator is communicated with the vacuum box, the coagulation box is communicated with the sewage box, and the screw stacking machine is used for carrying out solid-liquid separation on liquid dung in the coagulation box and liquid dung flocculated by chemical agents. The excrement liquid is subjected to coarse filtration through the solid-liquid separator to obtain tail water and excrement residues, wherein the separated tail water can be directly discharged to the first grid of the septic tank, fermentation precipitation is conducted through the function of the septic tank, and finally the tail water is discharged into a sewage pipe network. For a pit toilet which cannot discharge tail water or a septic tank with clear water discharge intention, the tail water obtained by coarse filtration enters the coagulation tank and is fully reacted and flocculated with a blended chemical agent, and then solid-liquid separation is carried out again by utilizing the volute machine to obtain clear water and excrement residues. Excrement residues separated by the coarse filtration and screw stacking machine are used as organic fertilizer raw materials, and clear water separated by the screw stacking machine can be recycled.

Description

technical field [0001] The invention relates to the technical field of environmental sanitation, in particular to a novel sewage suction and purification vehicle. Background technique [0002] Fertilizers for crops and plant growth will be produced in septic tanks, which are directly scooped and used for fertilization, which not only smells bad, but also carries a variety of pathogenic bacteria that endanger the environment and affect people's healthy life. Direct discharge of sewage will also pollute groundwater and soil . Existing conventional vehicles use rotating drums to roughly filter the dung water, and then carry out solid-liquid separation after flocculation with chemical agents. Due to the structural limitation of the drum coarse filter, not only the filtration accuracy is low, but also it is easy to block and the efficiency is low; and according to a vacuum suction type screw extrusion solid-liquid separation system disclosed in the patent, the tail water needs t...
