本项目采用原系统中已经更换淘汰的反渗透膜元件材料,新建浓水回用反渗透系统,实现了废旧膜材料的循环回收利用。项目工艺流程采用了除垢过滤及反渗透膜除盐技术,以强磁过滤器、加药装置、反渗透装置、反渗透清洗/冲洗装置等构成主要材料设备单元。工业实际运行结果表明,经本工艺处理后的产水可回用于生产,既可以作为反渗透的进水,又可继续处理成适用于锅炉的补给水。 相似文献

Quantitative assessment of the UV effects on aquatic ecosystems requires an estimate of the in-water radiation field. Actual ocean UV reflectances are needed for improving the total ozone retrievals from the total ozone mapping spectrometer (TOMS) and the ozone monitoring instrument (OMI) flown on NASA's Aura satellite. The estimate of underwater UV radiation can be done on the basis of measurements from the TOMS/OMI and full models of radiative transfer (RT) in the atmosphere-ocean system. The Hydrolight code, modified for extension to the UV, is used for the generation of look-up tables for in-water irradiances. A look-up table for surface radiances generated with a full RT code is input for the Hydrolight simulations. A model of seawater inherent optical properties (IOPs) is an extension of the Case 1 water model to the UV. A new element of the IOP model is parameterization of particulate matter absorption based on recent in situ data. A chlorophyll product from ocean color sensors is input for the IOP model. Verification of the in-water computational scheme shows that the calculated diffuse attenuation coefficient Kd is in good agreement with the measured Kd. 相似文献

含氧化石墨烯混合基质反渗透复合膜的制备及性能研究 总被引:2,自引:0,他引:2
以间苯二胺(MPD)为水相单体、均苯三甲酰氯(TMC)为油相单体,氧化石墨烯(GO)作为水相添加物,采用界面聚合法,制备了GO-PA(聚酰胺)/PSF(聚砜)混合基质反渗透复合膜。采用扫描电子显微镜表征了膜形貌,考察了该膜对氯化钠的截留性能及耐氯性。结果表明,聚酰胺反渗透膜填充氧化石墨烯后,其分离性能优于聚酰胺膜,且具有较好的耐氯性。随着氧化石墨烯含量的增加,膜的通量增大,当添加量为0.005%时,膜具有最大通量,为63 L/(m2.h)。 相似文献

We have further developed and improved the prototype oceanic Fraunhofer line discriminator by using a well-protected fiber-optic-wire cable and in-water electronic housing. We conducted a series of in situ measurements in clear ocean water in the Florida Straits. By comparing the reduced data with the Monte Carlo simulation results, we verify the Raman scattering coefficient B(r) with an excitation wavelength at 488 nm to be 2.6 x 10(-4)m(-1) [Appl. Opt. 29, 71-84 (1990)], as opposed to 14.4 x 10(-4) m(-1) [Appl. Opt.14, 2116-2120 (1975)]. The wavelength dependence of the Raman scattering coefficient is found to have an insignificant effect on the in-water light field. We also discuss factors that lead to errors. This study can be used as a basis for inelastic light scattering in the radiative transfer theory and will allow other inelastic light, e.g., fluorescence, to be detected with in situ measurements. 相似文献

A method for determining the ocean-bottom optical albedo R(b) from in-water upward and downward irradiance measurements at a shallow site is presented, tested, and compared with a more familiar approach that requires additional measurements at a nearby deep-water site. Also presented are two new algorithms for estimating R(b) from measurements of the downward irradiance and vertically upward radiance. All methods performed well in numerical situations at depths at which the influence of the bottom on the light field was significant. 相似文献
