Embodiment 1

[0026] Embodiment 1: Get 280kg of zeolite, 470kg of calcite, 80kg of attapulgite, 80kg of bentonite, and 80kg of bauxite. Put the above-mentioned ore into the calciner, calcined at 1400 degrees for 20 hours, select the calcined ore, send it to the jaw crusher for crushing, and then send it to the Raymond machine for grinding until it reaches a fineness of 600 mesh, and then add A small amount of phosphate rock powder compounding agent is used for compounding. Send the above-mentioned compounded minerals into the mixer for thorough mixing and then send them into the carbonization furnace for carbonization treatment. The powder after the above carbonization treatment is packed into a plastic bag with 50 kg as the unit of measurement, and then becomes the finished product of the ultrafine water quality improving powder produced by the preparation method of the present invention.

Embodiment 2

[0027] Embodiment 2: Get zeolite 360kg, calcite 550kg, attapulgite 150kg, bentonite 150kg, bauxite 150kg. Put the above-mentioned ore into the calciner, calcined at 1500 degrees for 24 hours, select the calcined ore, send it to the jaw crusher for crushing, and then send it to the Raymond machine for grinding until the fineness of 1000 mesh, and then add A small amount of phosphate rock powder compounding agent is used for compounding. Send the above-mentioned compounded minerals into the mixer for thorough mixing and then send them into the carbonization furnace for carbonization treatment. The powder after the above carbonization treatment is packed into a plastic bag with 50 kg as the unit of measurement, and then becomes the finished product of the ultrafine water quality improving powder produced by the preparation method of the present invention.

Abstract

The superfine water quality improving powder is prepared through mixing and calcining non-metal ore calcite, zeolite, attapulgite, bentonite and bauxite in certain proportion; selecting concentrate, crushing, grinding to reach fineness over 600 mesh, mixing the superfine powder and non-metal mineral composite agent through stirring; carbonizing the mixture powder and packing. The superfine water quality improving powder has no toxic matter and harmful matter and may be used in treating industrial effluent, domestic sewage, river water, etc., the treated water may reach the first and second water quality standard, and the used treating agent may be reused. The precipitate produced during the treatment may be reused or used as fertilizer or feed.

Description

Technical field [0001] The invention relates to an ultrafine water quality improving powder and a preparation method thereof. In particular, it is an ultra-fine water quality improving powder prepared by deep processing of non-metallic ores without any chemical substances. It can effectively purify chemical wastewater, papermaking and printing and dyeing wastewater, aquaculture water, domestic sewage, rivers, lakes, wells, ponds and other water. Background technique [0002] At present, there are dozens of purification and treatment methods for various industrial wastewater, domestic sewage, aquaculture water, and river, lake and well pond water, but most of them are treated by chemical and biological methods. Some of them are expensive to use, some have poor treatment effect, some have complex preparation process, some have large one-time industrial investment, some have many residues, some sediments cannot be recycled, and even cause relatively large secondary pollution. ...
