Embodiment Construction

[0031] Below in conjunction with embodiment, the present invention will be further described:

[0032] 1. Acidification treatment:

[0033] ①Acidification treatment of zeolite:

[0034] The zeolite is pulverized first, and the particle fineness is controlled at 0.5-0.8 mm; the preparation of dilute sulfuric acid includes the following components by weight percentage: 4% sulfuric acid with a concentration of 98%, and 96% water; the ingredients for acidification treatment include The following components: zeolite 60%, dilute sulfuric acid 40%; dilute sulfuric acid is slowly added to the zeolite for acidification treatment, and the acidification time is controlled at 24 hours.

[0035] ②Acidification treatment of attapulgite clay:

[0036] First, the attapulgite clay is crushed, and the particle fineness is controlled at 0.5-1.0 mm; the preparation of dilute sulfuric acid includes the following components by weight percentage: 3% sulfuric acid with a concentration of 98%, and 9...

Abstract

A process for preparing the calcined natural minerals adsorbing-filtering agent includes such steps as proportionally adding its raw materials into stirrer, mixing, pressing to become sheets, drying in the sun, pulverizing, calcining, cooling and packing. It is used for the non-calcined filtering plate (or block or core) to clean the animal or plant cultivating water.

Description

Technical field: [0001] The invention relates to an adsorption filter, in particular to a production method of a roasted natural mineral adsorption filter. Background technique: [0002] In order to improve the production efficiency and economic benefits of aquaculture water, most of the farms adopt high-density intensive cultivation. The balance ability of the water ecosystem is limited. High-density intensive cultivation and a large amount of feeding can easily cause insufficient dissolved oxygen in the water body, resulting in a large amount of organic matter in the water. , the algae grow too fast, the water color changes greatly, the pH value is unstable, and the ammonia nitrogen content exceeds the standard. In order to maximize the production capacity of the limited aquaculture water body, it is necessary to maintain good water quality environmental conditions, which must solve the water quality pollution caused by the corruption of organic matter such as loose, resid...
