Problems solved by technology

[0005] The Chinese invention patent of CN 101935105 B discloses a microbial water purifier for aquaculture water and its preparation method. The inventive method uses activated montmorillonite particles immobilized with Bacillus coagulans as the water purifier, and has the characteristics of simple preparation. But this inventive method only uses montmorillonite particles as adsorbent and Bacillus as degradant, which can only degrade organic macromolecules, and has the ability of deodorization, antibacterial, and adsorption, but cannot nitrify, photosynthesize, and reduce ammonia nitrogen. Reduce the content of heavy metal ions in polluted water, so its effect of purifying water is limited, and the promotion value is not great

Embodiment 1

[0021] The preparation method of biological water quality purifier comprises the following steps:

[0022]1) Put the gangue into a pulverizer to pulverize, pass through a 35-mesh sieve, and roast the gangue powder at 780°C for 2 hours to obtain a heat-activated gangue carrier sample; 2) Accurately weigh 10g of the activated gangue carrier, put it into In the iodine measuring bottle, sterilize with damp heat at 120°C for 20 minutes, add 1g of Streptococcus lactis and 2g of COD-degrading bacteria, put them in a shaker, shake at 30°C at a speed of 40r / min for 2 hours, then pour out the excess bacteria solution, add 40g of glutaraldehyde aqueous solution with a concentration of 2% was cross-linked at 2°C for 24 hours, then poured out the excess glutaraldehyde, washed 4 times with sterile water, and the immobilization of the complex bacterial flora was completed to obtain the microorganism-loaded water purification stone powder; 3) Weigh 120g of Moringa oleifera seed defatted powde...

Embodiment 2

[0024] The preparation method of the biological water quality purifier includes: activation, loading, extraction of flocculation active substances, preparation of nano-iron oxide, and compounding, specifically including the following steps:

[0025] 1) Activation: Pulverize coal gangue into a pulverizer, pass through a 65-mesh sieve, and activate the coal gangue powder by roasting at 800°C for 3 hours to obtain an activated gangue carrier sample; activated coal gangue has strong adsorption capacity, renewable, The advantage of low price can be used as a good carrier for the immobilization of microbial flora;

[0026] 2) Loading: Accurately weigh 15g of activated coal gangue carrier, put it into an iodine measuring bottle, sterilize it with damp heat at 121°C for 25 minutes, add 2g of Rhodopseudomonas palustris and 3g of Bacillus subtilis, put it in a shaker, Shake at 33°C at a speed of 60r / min for 2.5 hours, then pour out the excess bacterial liquid, add 50 g of 2.5% glutarald...

Embodiment 3

[0031] The preparation method of the biological water quality purifier includes: activation, loading, extraction of flocculation active substances, preparation of nano-iron oxide, and compounding, specifically including the following steps:

[0032] Activation: Put coal gangue into a pulverizer to crush, pass through a 50-mesh sieve, and activate the coal gangue powder by roasting at 800°C for 3 hours to obtain a heat-activated gangue carrier sample; coal gangue undergoes a strong endothermic reaction during high-temperature roasting and Dehydration reaction, and release a certain activity, coal gangue volume expansion after roasting, a large number of micropores are formed on the surface and inside, with the structural characteristics of micropores and mesopores, strong ion exchange and large adsorption Ability, heat-activated coal gangue can be used as a good carrier for immobilization of microbial flora due to its advantages of strong adsorption capacity, renewability and lo...

Abstract

The invention discloses a preparation method of a biological water purifier. The method comprises the steps of activation, loading, extraction of a flocculating active substance, preparation of nanometer iron oxide, and compounding. The biological water purifier can effectively remove ammonia nitrogen and nitrites from water, improve the water pollution, degrade organic macromolecules, reduce the eutrophication degree in water and decompose the organic macromolecules in water into carbohydrates, amino acids, vitamins and bioactive substances which can be absorbed by animals and plants, also can adsorb non-degradable substances, degrade heavy metal ions and inhibit the growth of algae, has a strong flocculation and precipitation effect on suspended solids in the water, and is safe and high-efficient biological water purifier.

Description

technical field [0001] The invention relates to the field of water purifiers, in particular to a preparation method of biological water purifiers. technical background [0002] 82% of people in China drink water from shallow wells and rivers, of which 75% are seriously polluted by bacteria that exceed the hygienic standard, and the drinking water population polluted by organic matter is about 160 million. For a long time, people have always believed that tap water is safe and hygienic. However, because of water pollution, today's tap water is no longer hygienic. A survey shows that there are as many as 2,221 chemical pollutants detected in tap water all over the world, some of which are identified as carcinogens or cancer promoters. Judging from the drinking standards of tap water, China is still at a relatively low level. Tap water can only be processed into potable water by sedimentation, filtration, chlorination and other methods. Adding chlorine to tap water can effect...
