The pretreatment equipment mainly includes: mechanical filtration (quartz sand filtration), activated carbon adsorption filter, and precision filter.
The mechanical filter is mainly used for removing suspended solids and mechanical impurities from water. The outer casing of the equipment is made of stainless steel, lined with natural rubber, and equipped with advanced water distributor. The interior medium is refined quartz sand and anthracite.
In addition to the above structural features, the activated carbon adsorber contains a certain proportion of activated carbon, which has a free adsorption capacity of more than 95% on free chlorine in water, and has a high removal rate for organic matter and chromaticity, and is generally used in combination with a mechanical filter.
First, filter material loading:
1. The mechanical filter generally adopts the double-layer filter material, the upper layer is anthracite to prevent the filter material from penetrating the filter cap, and the lower layer of Zui is the 1# quartz sand layer with the particle size of 1.6-3.2mm, and the upper layer is 2.4-2.6mm. Fine quartz sand layer of diameter.
2. The activated carbon adsorber except the lower layer is 1# quartz sand, the rest are all special activated carbon for granular water treatment.
Second, the operation instructions 1. When the raw water enters the water through the equipment, the normal operation state opens the flow regulating valve, the inlet valve and the outlet valve.
2. Filter material cleaning: After loading, clean the filter material by backwashing, open the upper exhaust valve, and then open the backwash valve and exhaust valve. The intake air volume is 5 liters/second. Meter 2, the air pressure is about 0.2 MPa, and the cleaning is performed. The process typically takes a few hours until the effluent clarifies to the end.
3. Washing and running: After the filter material is cleaned, open the lower exhaust valve and the inlet valve, close the backwashing and the upper exhaust valve to adjust the flow regulating valve, and enter the positive washing state. When the water is in the control, the water inlet control is at the filtration speed 6- At 10 meters / hour, the time is about 15-30 minutes. When the water quality meets the requirements, open the water outlet valve and close the new lower valve into normal operation.
4. Backwashing: After the filter is operated for a period of time, the pressure difference between the inlet and outlet of the filter is gradually increased due to the interception of a large amount of suspended solids. At this time, the backwashing is required. The backwashing operation is the same as the cleaning of the filter material, and the time is about 10-20 minutes. .
Third, the equipment cleaning requirements 1. Every three months to fill the filter material of the equipment, according to the requirements of cleaning.
2. Clean the equipment site every day.
3. Clean and disinfect the pipeline of the equipment every week.
The main purpose of the pretreatment part in the water treatment equipment is to remove suspended solids, microorganisms, colloids, dissolved gases and some organic substances in the raw water to create conditions for desalination and post-treatment processes, and to achieve electrodialysis, reverse osmosis, ion exchange and other equipment. Water requirements.
