Problems solved by technology

These wastewater treatments are different from the activated sludge treatment commonly used in traditional domestic sewage treatment. Among them, the Japanese RBS treatment system using natural purification method is a better treatment method developed for these wastewater treatment; BMW technology is the production of biological activity water, but the products in the biological reaction tanks in the two treatment systems are all imported, and the production of "active soil" whose main components are produced in specific areas of Japan is also limited.
These limit the popularization and cost reduction of this technology

Embodiment 1

[0027] Embodiment 1: Composition (Pellet) preparation method

[0028] Mix 40g of peat soil (pH 5.47), 20g of bentonite, 0.6g of calcium alginate and 15g of cement in a beaker, then spray a certain amount of distilled water into the beaker, stir while spraying water, and stop when the mixture is soft and hard. Spray with water and add the mixture to molds to form columns. The culture solution that has been prepared to form spores, such as Bacillus CGMCC13429: CICC23692: CICC20666 = 1:1:1 (the amount of bacteria is not less than ×10 8 cfu / ml), which can be sprayed in distilled water.

[0029] The following parts by weight of turf carbon soil 30-50, bentonite 10-30, calcium alginate 0.2-1, and cement 10-20 are also possible, and the rest of the operation steps are the same as above.

Embodiment 2

[0030] Example 2: Production of biologically active water (bioactive water; BW) and wastewater treatment effect

[0031] According to the ratio of DW 1000ml: pellet 12g: pumice 24g, make two groups of 1000ml active water; one group is Pellet, and the other group is Pellet (with bacteria added). After aeration for 4 days, the wastewater treatment experiment was carried out using the prepared BW.

[0032] 1. Experimental grouping

[0033] (1) prepare artificial waste water with 1L distilled water (DW), in 300ml Erlenmeyer flask, each Erlenmeyer flask gets 100ml artificial waste water, is divided into experimental group 1, experimental group 2;

[0034] (2) Prepare artificial waste water with 1L BW, in 300ml Erlenmeyer flask, each Erlenmeyer flask gets 100ml artificial waste water, is divided into experimental group 3, experimental group 4;

[0035] (3) Use 1L of BW (bacteria) to prepare artificial wastewater, put in 300ml Erlenmeyer flasks, take 100ml artificial wastewater from ...

Embodiment 3

[0048] Embodiment 3: the analysis of effective silicate concentration in the waste water

[0049] In order to study silicates (SiO 2 ) concentration and the effect of added bacillus on the wastewater treatment effect, the effective SiO in water was analyzed 2 concentration changes. Analysis of effective SiO in distilled water, BW, BW (bacteria) group 2 concentration. The result is as Figure 4 As shown, it was found that SiO in water after 4 days of aeration 2 This should be caused by aeration in the presence of pumice and pellet when making biologically active water, but the concentration in the BW (bacteria) group is lower than that in the BW group, indicating that the three bacteria added in the pellet consume SiO 2 , and in the laboratory-scale wastewater treatment reactor, the SiO in the aeration tank and reaction tank of the experimental group of pellet (bacteria) 2 The lowest concentration, indicating that the added silicic acid decomposing bacteria (Bacillus) con...

Abstract

The invention belongs to the technical field of environmental microbes and waste water treatment, and in particular relates to a biologically active water and its preparation method and application. The composition containing bacterial spores is prepared by using peat soil, bentonite, calcium alginate, cement, and containing bacillus. The finished composition and the pumice stone are put into water for aeration to produce biologically active water. Active water also applies biologically active water technology to treat high-concentration organic wastewater, which not only has high efficiency, but also does not produce secondary pollution. In addition, the cost is low, and it has both economic and environmental benefits.

Description

technical field [0001] The invention belongs to the technical field of environmental microbes and waste water treatment, and in particular relates to a biologically active water and its preparation method and application. Background technique [0002] my country is a country with the largest water consumption in the world, and it is also the country with the highest sewage discharge in the world. In 2016, China's urban sewage discharge reached 31.8 billion tons, an increase of 114% compared with the end of the "Eleventh Five-Year Plan". By the end of 2010, the total amount of urban and rural sewage discharge in my country was as high as 45.08 billion tons. Among them, the total sewage discharge of 657 cities is 37.87 billion tons, and the total sewage discharge of 1633 counties is 7.21 billion tons. With the development of the economy, all kinds of pollution problems are serious, among which the water pollution problem is very prominent. As we all know, wastewater mainly ...
