Embodiment 1

[0028] The embodiment is basically as attached figure 1 Shown:

[0029] The sewage treatment process adopts a coagulation machine for coagulation treatment, and the coagulation machine includes an outer bucket 1, an inner bucket 2 and a medicine bucket 7.

[0030] A water injection pipe 10 , a drain pipe 11 and an interlayer 8 are arranged between the outer tub 1 and the inner tub 2 . The water injection pipe 10 is located at the top of the outer barrel 1 and the inner barrel 2; the drain pipe 11 is located at the bottom of the outer barrel 1 and the inner barrel 2, and the drain pipe 11 is provided with a drain valve 110 .

[0031] The inner barrel 2 is provided with an upper stirring rod 3 , a middle stirring part and a lower stirring rod 5 . Both the upper stirring rod 3 and the lower stirring rod 5 are provided with a plurality of arc-shaped blades 31 . In this embodiment, each stirring rod is provided with four arc-shaped blades 31 , which are symmetrical left and righ...

Embodiment 2

[0041] The difference between this embodiment and embodiment 1 is: in step A, the coagulant includes 20kg aluminum sulfate and 5kg polyaluminium chloride by mass; in step B, the volume of sewage accounts for 9 / 10 of the volume of the inner barrel; The time is 10 minutes.

Abstract

The invention belongs to the technical field of sewage treatment, and specifically relates to a sewage treatment process; a coagulation machine is used for coagulation treatment, and the coagulation machine includes an outer barrel, an inner barrel and a medicine barrel; a water injection pipe and a drainage pipe are arranged between the outer barrel and the inner barrel and the interlayer; the upper stirring rod, the middle stirring part and the lower stirring rod are arranged in the inner barrel, and the leaking net for supporting the floc is arranged at the bottom of the inner barrel; the active rod, the passive rod and the pumping mechanism are arranged in the interlayer; the active rod is equipped with Screw rod, bevel gear 1 and water wheel; bevel gear 2, driving gear, first bevel gear pair and second bevel gear pair are arranged on the passive rod. The coagulation treatment steps include: A, adding coagulant; B, water injection; C, pumping water; D, standing still; E, draining. This scheme can automatically reduce the stirring speed according to the generation of flocs in the coagulation process, and simplify the coagulation process.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a sewage treatment process. Background technique [0002] Sewage treatment methods include physical treatment, chemical treatment and biological treatment. Among them, the chemical treatment method is a wastewater treatment method that separates and removes dissolved and colloidal pollutants in wastewater or converts them into harmless substances through chemical reactions and mass transfer. In the chemical treatment method, the treatment units based on the chemical reaction produced by adding chemicals are: coagulation, neutralization, redox, etc. [0003] Compared with other physical and chemical methods, the coagulation-sedimentation process has the advantages of good effluent quality, stable and reliable process operation, economical and practical, and easy operation. The principle of coagulation and sedimentation is to add some chemicals (commonly know...
