1. Temperature: during the operation of multi-media filter in the process of water quality treatment, if the temperature is lower and lower, the viscosity of raw water will become larger and larger, and the filtration speed of the equipment will slow down, thus making its water production efficiency lower. In the case of making the same amount of water, the time spent will increase with the decrease of temperature. The viscosity of liquid is an exponential function of temperature, which decreases rapidly with the increase of temperature. To a certain extent, heating is a simple and effective measure to reduce viscosity, and also an effective measure to speed up the production efficiency of ultra pure water.

2、水壓：多介質過濾器水質的過濾工作需要借助壓力來完成，只有在合適的壓力下才能對水起到好的過濾效果。壓力如果過小，水產量就會變小，設備的制水效率降低。壓力過大，也不利于多介質過濾器的工作，長期壓力過大，會加快多介質過濾器的老化，也會加劇濾料的損耗，給使用增加了成本。

2. Water pressure: the water quality filtration of multi-media filter needs to be completed with the help of pressure. Only under the appropriate pressure can the water have a good filtering effect. If the pressure is too small, the water yield will be reduced and the water production efficiency of the equipment will be reduced. If the pressure is too high, it is not conducive to the work of the multi-media filter. If the pressure is too high for a long time, the aging of the multi-media filter will be accelerated, and the loss of the filter material will be increased, which will increase the cost of use.

3、雜質的含量和種類：多介質過濾器使用的主要目的就是為了去除水中的各種雜質，但是各地區(qū)水中的雜質種類不同，使用多介質過濾器沒能很好的進行去除，這時就需要添加一定的預處理，先將水中的大顆粒物質沉淀掉。

3. Content and type of impurities: the main purpose of multi-media filter is to remove all kinds of impurities in water. However, the types of impurities in water are different in different areas, and the use of multi-media filter can not remove them well. At this time, it is necessary to add certain pretreatment to precipitate the large particles in the water.

多介質過濾器的維護與保養(yǎng)需要對設備本身來進行要求，明確多介質過濾器維護保養(yǎng)的目的，可以及時的處理設備在運行過程中由于技術狀態(tài)的變化而引起的大量的問題，可以隨時的改善設備的技術狀況，保證正常的運行，延長多介質過濾器的使用壽命。

The maintenance and maintenance of the multi-media filter requires the equipment itself. The purpose of the maintenance of the multi-media filter is clear. It can timely deal with a large number of problems caused by the change of technical status in the operation process of the equipment. It can improve the technical status of the equipment at any time, ensure the normal operation, and extend the service life of the multi-media filter.

多介質過濾器一旦出現(xiàn)了損壞通常會導致正常的運行失敗，所以需要及時的對設備進行定期的檢查、保養(yǎng)與維護。使用一定的工時用于維護保養(yǎng)。對設備中的各種部件進行檢修，關注濾料的情況。

Once the multi-media filter is damaged, it usually leads to normal operation failure, so it is necessary to timely carry out regular inspection, maintenance and maintenance of the equipment. Use certain working hours for maintenance. Overhaul various parts of the equipment and pay attention to the condition of filter materials.

主要的部件應設專卡記錄產地、、運行狀況、維修次數(shù)、保養(yǎng)人等。所有設備應有足夠的零配件，在寒冷地區(qū)冬季使用時，尤其需要注意室外管道、閘門、水泵等設備的防凍保溫工作。

Special card should be set for main parts to record the place of origin, price, operation status, repair times, maintenance personnel, etc. All equipment should be equipped with enough spare parts. When it is used in winter in cold areas, special attention should be paid to the anti freezing and thermal insulation work of outdoor pipelines, gates, pumps and other equipment.
