Matters needing attention in installation of sludge drying equipment in sewage plant

In the process of wastewater treatment, a large number of suspended solids will be produced, that is, sewage sludge, which has the characteristics of high humidity and high viscosity, so it is difficult to treat. After sludge thickening, sludge dewatering and other pretreatment, the water content is still very high, and the sludge volume is very large. It is necessary to improve the solid content of sludge cake through sludge drying equipment of sewage treatment plant, so as to reduce the area of sludge stacking and facilitate the transportation, storage and resource utilization of sludge. As an important device for material dehydration and drying, it is very important to install the sludge drying equipment.

1. Familiar with technical documents and equipment structure

Before formally installing the sludge drying equipment in the sewage plant, the technicians need to understand the installation drawings and relevant technical documents of the equipment, and be familiar with the components, assembly sequence and assembly technology of the equipment. Before the formal start of installation, prepare the tools needed in the installation process, determine the correct assembly sequence and method according to the actual situation in the installation process, and formulate the appropriate construction technical scheme.

2. Maintenance before installation

Before the installation of sludge drying equipment in sewage treatment plant, all parts need to be cleaned, coated with lubricating oil, and then sealed for storage. This is to prevent the parts of the equipment from rusting or being polluted.

3. Inspection before installation

After the arrival of all parts of the sludge drying equipment in the sewage plant, the technicians need to check the spare parts of the equipment to see whether the quantity of spare parts is enough, whether the quality of all parts of the equipment is qualified, and whether there is any damage to the spare parts in the process of transportation. After carefully checking the integrity and quality of the accessories, if there is no problem, the next step of installation can be carried out. If it is found that the number of parts is insufficient or there are defects in the process of manufacturing and storage, it is necessary to contact the manufacturer in time for treatment or correction.

4. Operation points during installation

In the process of installation, it is necessary to transport the parts of sludge drying equipment in sewage treatment plant. Steel wire rope, hook and other tools should be used. In the process of transportation, direct contact between steel wire rope and the working surface of parts should be avoided to ensure the balance of horizontal transportation of parts.
