Embodiment Construction

[0023] The present invention will be further described below in conjunction with accompanying drawing:

[0024] Such as Figure 1-Figure 4 As shown, a process method for treating domestic sewage and paper mill sewage, the sewage is sent from the sewage inflow pipe 9 into the sewage settling chamber 10, and the settling pressure pump 11 pressurizes the sewage, so that the sewage in the sewage is settled. The settled matter enters the dirt collection chamber 12, and the settled sewage enters the chemical purification tank 4, the liquid level sensor 6 senses the amount of sewage entering the chemical purification tank 4, the concentration sensor 5 senses the concentration of chemical substances in the sewage, and The signal is transmitted to the operation control room 8, and the dosing amount calculation module 804 calculates the dosing amount, drives the medicine powder storage box 7 to dosing in the chemical purification box 4, and the sewage enters the secondary filter box 3 a...

Abstract

The invention discloses a technological method and apparatus for treating domestic sewage and sewage in a papermaking factory. The apparatus comprises a pure water outlet pipe, an electromagnetic flowvalve, a secondary filtering box, a chemical purifying box, a liquid level sensor, a chemical powder storage box and an operation control chamber, wherein the liquid level sensor is installed above aconcentration sensor, the chemical powder storage box is installed above the liquid level sensor, a sewage inlet pipe is installed below the operation control chamber, a sewage settling chamber is installed below the sewage inlet pipe, a settling pressurizing pump is installed below the sewage settling chamber, a pollutant collection chamber is installed below the settling pressurizing pump, anda chemical amount sensor is installed inside the chemical powder storage box. The apparatus has the beneficial effects that the amount of the sewage can be sensed, the appropriate amount of chemical powder can be fed, the problem of excessive chemical powder or insufficient chemical powder can be solved, the PH of the sewage can be adjusted, and the effect for purifying the sewage is good.

Description

technical field [0001] The invention relates to the field of sewage treatment equipment, and the invention relates to a process method and a device for treating domestic sewage and paper mill sewage. Background technique [0002] Papermaking wastewater refers to the wastewater generated during the pulping and papermaking process. Including pulping and cooking waste liquid, washing waste water, bleaching waste water and paper machine white water, etc. Papermaking wastewater has complex components and poor biodegradability. It belongs to difficult industrial wastewater and is one of the main sources of industrial pollution in my country. my country's paper industry mostly uses grass stalks, wood pulp, etc. as papermaking raw materials. Pulping and papermaking production generally consists of pulping, pulp washing, bleaching, and papermaking processes. Pulping in the paper industry includes alkaline pulping, chemical mechanical pulping and mechanical pulping. According to d...
