一、引言随着现代农业的发展，养殖业作为重要的农业产业之一，对环境的影响也日益凸显。养殖废水是养殖业的重要副产品，如果不加以处理，会对周边环境和水资源造成严重污染。因此，养殖废水的处理和达标排放显得尤为重要。本文将探讨养殖废水达标农灌水标准与达标排放之间的主要区别。

二、养殖废水达标农灌水标准

养殖废水达标农灌水标准是指经过处理后的养殖废water，其water质满足农田灌溉用water的standards。这一standard实施，可以有效利用nourished waste resources减轻对环境压力，又可以保障nourished water quality促进agriculture production.

The standard typically includes the following aspects:

a. The concentration of toxic and harmful substances such as heavy metals and pesticides in the wastewater should be lower than the specified limits.

b. The concentration of nutrients such as nitrogen and phosphorus in the wastewater should be controlled within an appropriate range to avoid excessive input leading to eutrophication of water bodies.

c. The pH value of the wastewater should be within an appropriate range to ensure biological activity for irrigation water.

三、養畜廢料達標排放

養畜廢料達標排放是指經過處理後之養畜廢料，其排放之water質達到國家或地方規定的標準。此乃更為嚴格之排放要求，以保護源頭地之安全防止污染物進入地下及地表。

The standard typically includes the following aspects:

a. The concentration of toxic and harmful substances such as heavy metals and pesticides in the wastewater should be lower than national or local regulations.

b. The concentration of nutrients such as nitrogen and phosphorus in the wastewater should be controlled within national or local regulations.

c. The pH value of the wastewater should remain at an appropriate range, ensuring ecological functionality for discharge into receiving waters.

四、小知识：環保用語COD, BOD, BOD5, SS, TSS是什么意思？

COD: Chemical Oxygen Demand (Chemical需氧量)

BOD: Biological Oxygen Demand (五日生物需氧量) - represents a comprehensive indicator for organic pollutants

SS: Suspended Solids (悬浮固体)

TSS: Total Soluble Solid (總溶解固體)

These are indicators used in water treatment to evaluate water quality; specific understanding can refer directly to Wikipedia or related articles on these terms with national standards prescribed analytical testing methods.

另外CC is not commonly used term except during processing stages before using it.

五、養畜污染（廢）料幾種排放標準介紹：

1., GB18595-2001国家禽畜产业泵导线基础设施

最高允许日均浓度为化学需氧量400mg/L；悬浮物200mg/L；氨氮含量80mg/L；总磷10mg/L。

2., GB18596-2001国家禽畜产业泵导线基础设施新标准

最高允许日均浓度为化学需氧量150mg/L；悬浮物150mg/L；氨氮含量40mg/L；

3., 广东省珠三角地区禽畜产业泵导线基础设施

最高允许日均浓度为化学需氧量380mg/L；

4., 农田灌溉GB5084-2005

水作：最高允许日均浓度为化学需氧量300g/m³；

悬浮物100g/m³；

氨氮20g/m³；

总磷10g/m³。
