GB/T 7488-1987 水质 五日生化需氧量(BOD5)的测定稀释与接种法

本方法适用于BOD大于或等于2mg/L并且不超过6000mg/L的水样。BOD大于6000mg/L的水样仍可用本方法，但由于稀释会造成误差，有必要要求对测定结果做慎重的说明。 本试验得到的结果是生物化学和化学作用共同产生的结果，它们不象单一的、有明确定义的化学过程那样具有严格和明确的特性，但是它能提供用于评价各种水样质量的指标。 本试验的结果可能会被水中存在的某些物质所干扰，那些对微生物有毒的物质，如杀菌剂、有毒金属或游离氯等，会抑制生化作用。水中的藻类或硝化微生物也可能造成虚假的偏高结果。

GB 6920-1986 水质 pH值的测定 玻璃电极法

1.1 本法适用于饮用水、地面水及工业废水pH值的测定。 1.2 水的颜色、浊度、胶体物质、氧化剂、还原剂及高含盐量均不干扰测定；但在pH＜1的强酸性溶液中，会有所谓“酸误差”，可按酸度测定；在pH＞10的碱性溶液中，因有大量钠离子存在，产生误差，使读数偏低，通常称为“钠差”。消除“钠差”的方法，除了使用特制的“低钠差”电极外，还可似选用与被测溶液的pH值相近似的标准缓冲溶液对仪器进行校正。 温度影响电极的电位和水的电离平衡。须注意调节仪器的补偿装置与溶液的温度一致，并使被测样品与校正仪器用的标准缓冲溶液温度误差在±1℃之内。

ISO 13160:2021 水质. 锶90和锶89. 利用液体闪烁计数或比例计数法的试验方法

This document specifies conditions for the determination of 90Sr and 89Sr activity concentration in samples of environmental water using liquid scintillation counting (LSC) or proportional counting (PC). The method is applicable to test samples of drinking water, rainwater, surface and ground water, marine water, as well as cooling water, industrial water, domestic, and industrial wastewater after proper sampling and handling, and test sample preparation. Filtration of the test sample and a chemical separation are required to separate and purify strontium from a test portion of the sample. The detection limit depends on the sample volume, the instrument used, the sample count time, the background count rate, the detection efficiency and the chemical yield. The method described in this document, using currently available LSC counters, has a detection limit of approximately 10 mBq l−1 and 2 mBq l−1 for 89Sr and 90Sr, respectively, which is lower than the WHO criteria for safe consumption of drinking water (100 Bq·l−1 for 89Sr and 10 Bq·l−1 for 90Sr)[3]. These values can be achieved with a counting time of 1000 min for a sample volume of 2 l. The methods described in this document are applicable in the event of an emergency situation. When fallout occurs following a nuclear accident, the contribution of 89Sr to the total amount of radioactive strontium is not negligible. This document provides test methods to determine the activity concentration of 90Sr in presence of 89Sr. The analysis of 90Sr and 89Sr adsorbed to suspended matter is not covered by this method. It is the user’s responsibility to ensure the validity of this test method selected for the water samples tested.

ISO 13163:2021 水质. 铅-210. 利用液体闪烁技术法的试验方法

This document specifies a method for the measurement of scintillation counting (LSC). 210Pb in all types of waters by liquid The method is applicable to test samples of supply/drinking water, rainwater, surface and ground water, as well as cooling water, industrial water, domestic, and industrial wastewater after proper sampling and handling, and test sample preparation. Filtration of the test sample is necessary. Lead-210 activity concentration in the environment can vary and usually ranges from 2 mBq l-1 to 300 mBq l-1 [27][28]. Using currently available liquid scintillation counters, the limit of detection of this method for 210Pb is generally of the order of 20 mBq l-1 to 50 mBq l-1, which is lower than the WHO criteria for safe consumption of drinking water (100 mBq l−1).[4][6] These values can be achieved with a counting time between 180 min and 720 min for a sample volume from 0,5 l to 1,5 l. Higher activity concentrations can be measured by either diluting the sample or using smaller sample aliquots or both. The method presented in this document is not intended for the determination of an ultra-trace amount of 210Pb. The range of application depends on the amount of dissolved material in the water and on the performance characteristics of the measurement equipment (background count rate and counting efficiency). The method described in this document is applicable to an emergency situation. The analysis of Pb adsorbed to suspended matter is not covered by this method. It is the user’s responsibility to ensure the validity of this test method for the water samples tested.

ISO 16075-3:2021 灌溉工程中已处理过的废水的使用指南. 第3部分: 用于灌溉的再利用方案组件

This document covers the system's components needed for the use of treated wastewater (TWW) for irrigation. Emphasis is placed on irrigation methods, mainly drip irrigation, as this method represents an efficient method of irrigation and water saving, while reducing the pollution of the crops. Despite the fact that water quality and filtration of treated wastewater (herein TWW) using drip irrigation are critical, open irrigation systems are more popular and are frequently used for irrigation with TWW and therefore are covered in this document. This document covers issues related to the main components of a TWW irrigation project, including the following: — pumping stations; — storage reservoirs; — treatment facilities (for irrigation purposes); — filtration and disinfection; — distribution pipeline networks; — water application devices: irrigation system components and treatment. This document is not intended to be used for certification purposes.

ISO 16075-4:2021 灌溉工程使用处理过的废水指南. 第4部分: 监测

This document provides recommendations regarding: — monitoring the quality of treated wastewater (TWW) for irrigation; — monitoring irrigated plants; — monitoring the soil with regard to salinity; — monitoring natural water sources in neighbouring environments; — monitoring the quality of water in storage reservoirs. It puts emphasis on sampling methods and their frequency. Regarding the methods of analysis, this document refers to standard methods or, where not available, to other bibliographical references. NOTE In cases where a monitoring plan already exists, these recommendations can be integrated into this plan. This is notably the case when a broader approach of risk management is implemented, such as the water safety plans (serving as a model for sanitation safety plans) developed by WHO[16].

Guidelines for treated wastewater use for irrigation projects - Part 2: Development of the project

ISO 16075-1:2020 灌溉工程中已处理过的废水的使用指南. 第1部分: 用于灌溉的再利用方案基础

This document contains guidelines for the development and the execution of projects intending to use treated wastewater (TWW) for irrigation and considers the parameters of climate and soil. The purpose of this document is to provide guidance on all elements of a project using TWW for unrestricted and restricted irrigation, including design, materials, construction, and performance, when used for the following: — irrigation of agricultural crops; — irrigation of public and private gardens and landscape areas, including parks, sport fields, golf courses, cemeteries, etc. These guidelines are intended to provide assistance for the benefit of users of TWW for irrigation. The guidelines relate to the widespread and common ranges of water quality rather than exceptional or unique ones and are intended for the use of professionals, such as irrigation companies (designers and operators), agricultural extension officers or advisors, water companies (designers and operators), local authorities and water utilities. The use of these guidelines by users might require additional specifications. None of the parts of this document are intended to be used for certification purposes. These guidelines suggest the parameters of TWW quality. These parameters include the following: — agronomic parameters: nutrients (nitrogen, phosphorus and potassium), salinity factors (total salt content, chloride, boron, and sodium concentration) and heavy metals’ concentration; — pathogen presence. Each of these parameters can have possible impacts on the crops, soil, and public health. The guidelines discuss the possibility of preventing the contaminants’ addition during wastewater production and the ability to remove them during the course of treatment. Contaminants of emerging concern (such as pharmaceuticals and personal care product residuals) are outside the scope of this document since up to day, there is no evidence of adverse effects on human health or environment via irrigation with TWW or via the consumption of crops irrigated with TWW. The project should be designed in accordance with the sanitary quality of the TWW in order to avoid disease transmission by the pathogens in the water. The use of these guidelines is encouraged to ensure consistency within any organization engaged in the use of treated wastewater. These guidelines provide the basis for a healthy, hydrological, environmental and agronomic conscious design, operation, monitoring, and maintenance of an irrigation system using treated wastewater.
