Problems solved by technology

[0004] The purpose of the present invention is to overcome the above-mentioned existing sewage treatment, because the sewage treatment equipment needs power supply, so there are cables, but the method of cable laying and cable head production is unreasonable, resulting in unstable power supply and low sewage treatment efficiency. A method for cable laying and cable head production in sewage treatment is designed. The cable head produced by this method meets the requirements, the quality of the cable after laying meets the requirements, and the efficiency of sewage treatment is guaranteed.

Embodiment

[0014] The cable laying and cable head manufacturing method in sewage treatment includes the following steps:

[0015] (1) Be fully familiar with the drawings before laying the cables, and compile the cable construction sequence table and the cross-sectional arrangement diagram according to the design requirements to prevent the cables from being improperly placed and crossed;

[0016] (2) The cable should start from the power distribution room, and the cable should be laid far and then near. The margin during the cable laying process should be appropriate and should not be tightened. The terminal head should be reserved for a spare length of 1-1.5m. Fasten the signs in time, and seal the saw fracture to prevent moisture;

[0017] (3) When cables are laid in a horizontal bridge, they should be fixed with PVC cable ties. When they are laid in a vertical bridge, they should be fixed with clips. The arrangement of cables, power cables and control cables should not be arranged on the sam...

Abstract

The invention discloses a cable laying and cable head manufacturing method in sewage treatment. The cables are laid from a far position to a new position, and are in different sections and areas by taking the power distribution chamber as a starting point, the sealing and damp-proof measures are carried out on the saw fracture; when the cables are laid in a bridge frame at the vertical position, the cables are clamped by clamps, the cables are arranged in such a way that the electric power cables and the control cables are not required to be arranged on the same layer of support, a high-low voltage power cable, strong current, weak current and weak current control cables are arranged in layers sequentially, alternating current single-core power cables are arranged on the supports at the same side and are arranged in a manner of a tightly attached triangle, and are fastened with bandages every 1m, the fixing clamps of the single-core power cables cannot form a closed ferromagnetic loopwith non-magnetic clamps; and after the cables are laid, the cable grooves and the cable protection tubes, and the flame-retardant blocking materials for the flammable places are subjected to fireproof sealing and blocking at the port of the building, and the cover plate can be timely in time. The cable head manufactured by the method meets the requirements, the quality of the cables after being laid is met, and the sewage treatment efficiency is guaranteed.

Description

Technical field [0001] The invention relates to a method, in particular to a method for laying cables and making cable heads in sewage treatment. Background technique [0002] Sewage usually refers to polluted water discharged from life and production. Sewage mainly includes domestic sewage, industrial wastewater and initial rainwater. The main pollutants of sewage include pathogenic pollutants, oxygen-consuming pollutants, plant nutrients and toxic pollutants. From the perspective of the source of sewage, sewage can be defined as liquid or water discharged from residential, government, commercial, or industrial areas mixed with groundwater, surface water, snowstorms, etc. that carry waste. There are many types of sewage, and there are many technologies and processes to reduce the environmental impact of sewage. According to the source of sewage, sewage can be divided into these four categories. The first category: industrial wastewater wastewater from manufacturing, mining a...
