Description
技术领域 technical field
本实用新型属于水处理技术领域,尤其涉及一种用于对江河流域、湖泊、水库或蓄水池的水体进行除藻过滤的水处理装置。The utility model belongs to the technical field of water treatment, in particular to a water treatment device used for algae removal and filtration of water bodies in river basins, lakes, reservoirs or reservoirs.
背景技术 Background technique
在民用水及工业用水的水处理过程中,通常需要对取自江河流域、湖泊、水库或蓄水池的水体进行除藻处理。现有的除藻技术主要有以下几类:一类是采用机械筛除的固液分离的方法,如用微滤机,微滤机滤网的孔眼孔径为10~45μm(多数为35μm),除藻率可达50%~70%,微滤机对藻类的去除率随藻的种类不同而有区别,越细小的藻类越难去除,存在长时间使用滤网过滤,滤网需经常拆洗,频繁的拆装机器的不足,不仅耗费人力,还极易把机器损坏,减少机器的使用寿命;另一类是利用膜技术的过滤除藻装置,膜技术是利用离子交换膜或有机高分子合成膜组成的机理,依据膜孔径的不同,可分为微滤、超滤、纳滤和反渗透,虽然该技术是当今唯一能够做到100%除藻的技术,但是由于膜技术需要较高的基建投资和运行费用,目前很少用在大规模的生产实践中;还有一类气浮池式的除藻装置,该装置采用容器机械收获藻的办法,气浮池宜用于浊度小于100NTU的含藻水,但这种装置固液分离速度较小,因此占地面积较大,而且若污泥处理不当会造成二次污染。In the water treatment process of domestic water and industrial water, it is usually necessary to carry out algae removal treatment on water bodies taken from river basins, lakes, reservoirs or cisterns. The existing algae removal technology mainly contains the following categories: one is the method of solid-liquid separation using mechanical screening, such as using a microfilter, the aperture of the filter screen of the microfilter is 10-45 μm (mostly 35 μm), The algae removal rate can reach 50% to 70%. The algae removal rate of the microfilter varies with the type of algae. The finer the algae is, the harder it is to remove. There is a long-term use of the filter to filter, and the filter needs to be removed and washed frequently. The lack of frequent disassembly and assembly of the machine not only consumes manpower, but also easily damages the machine and reduces the service life of the machine; the other is the filter algae removal device using membrane technology, which uses ion exchange membrane or organic polymer synthesis The mechanism of membrane composition can be divided into microfiltration, ultrafiltration, nanofiltration and reverse osmosis according to the different membrane pore sizes. Although this technology is the only technology that can achieve 100% algae removal, the membrane technology requires high Infrastructure investment and operating costs are rarely used in large-scale production practice at present; there is also a type of air flotation tank type algae removal device, which adopts the method of harvesting algae mechanically in a container, and the air flotation tank is suitable for turbidity less than 100NTU. Algae water, but the solid-liquid separation speed of this device is small, so it occupies a large area, and if the sludge is not properly treated, it will cause secondary pollution.
CN2490153公开了一种“双场式除藻杀菌消毒器”水处理装置,它主要在外壳中设置两个水处理电场,由电能发生器的输出正、负极接入两个电场中的阳极管和阴极管。待处理水经进口流入后,通过两个水处理电场的先后处理,达到除藻杀菌消毒的目的,但采用电能发生器,存在能耗大的问题。因此,目前市场上急需一种清洗方便、投资较少、除藻效果好的除藻型过滤器来解决现有技术中存在的问题。CN2490153 discloses a "dual-field type algae removal and sterilizer" water treatment device, which mainly sets two water treatment electric fields in the casing, and the positive and negative electrodes of the electric energy generator are connected to the anode tube and the cathode tube. After the water to be treated flows in through the inlet, it is treated successively by two water treatment electric fields to achieve the purpose of algae sterilization and disinfection. However, the use of electric energy generators has the problem of large energy consumption. Therefore, there is an urgent need for an algae-removing type filter with convenient cleaning, less investment and good algae-removing effect on the market to solve the problems in the prior art.
