近年來，人們對水質淨化技術的需求日益增加。水質淨化不僅可以提高飲用水的質量，還可以保護環境和減少水污染。在水質淨化領域，二氧化氯和腐植酸等技術被廣泛應用，以確保水質達到標準。
另一方面，動物飼品批發市場也在逐漸增長。隨著人們對寵物和農場動物的關注增加，對高質量動物飼品的需求也在上升。茶粕是一種常見的動物飼料，含有豐富的營養物質，對動物的生長和健康非常有益。
除了水質淨化和動物飼品批發，建材五金和動物藥品批發也是市場上的熱門領域。建材五金如螺絲、螺帽和鉚釘等金屬製品在建築和製造行業中不可或缺，而動物藥品的需求也在不斷增加，以保護動物免受疾病和寄生蟲的侵害。
總的來說，水質淨化技術和動物飼品批發市場的需求正在持續增長，為相關行業帶來了商機和機遇。
