Description
Technical Field
The invention belongs to the technical field of surface water purification treatment, and particularly relates to a natural mineral restoration agent for quickly eliminating slight black and odorous water.
Background
Along with the development of modern society becoming faster and faster, the people's living standard is continuously improved, and a large amount of domestic sewage, agricultural irrigation water, domestic garbage, industrial wastewater and surface runoff with larger pollution load directly flow into the water, so that the concentration of the ammonia nitrogen in the riverway is higher, and in the practical engineering application, how to reduce the concentration of the ammonia nitrogen in the water, how to improve aerobic and facultative anaerobic microorganisms in sludge and digest sludge are the key of the method for improving the water quality of the water and comprehensively treating black and odorous water. The existing water purifying agent almost adopts a chemical preparation formula, although the formula has a certain effect on treating the water quality of black and odorous water, the water quality is difficult to meet the requirement of aquaculture, and the water quality can be repeatedly deteriorated along with residual baits and culture excrement generated in the aquaculture process, at the moment, a water purifying agent product without harm, simple operation, low cost and good practicability needs to be added, and the conventional chemical preparation has no continuity and great harm and cannot meet the requirement.

The natural zeolite powder is 180-mesh and 200-mesh, and the purity is more than 70 percent.
The diatomaceous earth porosity is greater than 80%.
The modified clay is prepared by cation modification, and the preparation method comprises the following steps of mixing the raw materials in a solid-to-liquid ratio of 1: 10 placing clay into an aluminum salt/magnesium salt (molar ratio is 4: 1) mixed solution with a certain concentration (0.21mol/L, calculated as magnesium salt) and stirring for 2h, standing for 4h, then carrying out suction filtration, washing for a plurality of times by using distilled water, drying for 1h at 80 ℃, grinding, and then sieving by using a 80-mesh sieve to obtain the modified clay required by the mineral restoration agent.
The weight of the natural zeolite powder, the diatomite, the modified clay, the bentonite and the diagenetic mineral is measured by dry weight.
The preparation raw materials comprise 60% of natural zeolite powder, 10% of diatomite, 10% of modified clay, 10% of bentonite and 10% of diagenetic mineral.
The preparation raw materials comprise 75% of natural zeolite powder, 5% of diatomite, 6% of modified clay, 8% of bentonite and 6% of diagenetic mineral.
The preparation raw materials comprise 80% of natural zeolite powder, 5% of diatomite, 5% of modified clay, 5% of bentonite and 5% of diagenetic mineral.
The preparation raw materials comprise 80% of natural zeolite powder, 7% of diatomite, 5% of modified clay, 5% of bentonite and 3% of diagenetic mineral.
Compared with the prior art, the invention has the following advantages:
the invention takes natural mineral substances as main components, adds the natural mineral substances into the water body to be treated after being dissolved by water, has convenient operation, and is environment-friendly and free from secondary pollution after being used. When the mild black and odorous water is treated, the transparency of the water can be rapidly improved, the peculiar smell of the water can be eliminated, the turbidity can be reduced, a good microorganism growth environment is constructed in the water when the device is used, a wide metabolism space is provided for beneficial microorganisms, microorganism populations with different aerobic degrees from top to bottom and from outside to inside are respectively formed, and the microorganism populations are rapidly and naturally precipitated. Because the natural zeolite powder and the diatomite in the repairing agent have high porosity, a certain amount of oxygen is carried after the repairing agent enters a water body to activate aerobic and facultative anaerobic microorganisms in the sludge, organic matters in the sludge are decomposed, the upper-layer sludge is gradually desertified, the lower-layer sludge is covered, the release of organic pollutants in the lower-layer sludge to a water phase is prevented, and the final effect is that the sludge is reduced, and the black and odorous phenomenon is not easy to relapse. The invention takes natural mineral substances as main components, can be added into dry powder, can also be used after being dissolved by water, has convenient operation, is environment-friendly and does not generate secondary pollution after being used, has reduction effect on bottom mud, can save dredging cost, has long treatment effect and is not easy to relapse. When treating the surface water and aquaculture wastewater of the fifth kind of inferiority, the pollutants such as COD, ammonia nitrogen, total phosphorus and the like in the water body can be quickly reduced. Because the natural zeolite powder in the mineral restoration agent has strong adsorption performance on ammonia nitrogen, more than 90% of ammonia nitrogen in the water body can be removed, and therefore, the mineral restoration agent has a good purification effect on the water body with the ammonia nitrogen exceeding the standard.
