Embodiment 1

[0026] A biological agent for treating gray water from cable trenches, the method for treating gray water with the preparation comprises the following steps:

[0027] (1) Put the gray water into the sedimentation tank for sedimentation: the gray water of the power plant enters the sedimentation tank for sedimentation, remove suspended matter, and adjust the pH value to 7-8;

[0028] (2) Put the biological agent into the wastewater treated in step (1), wherein the weight ratio of the biological agent to the wastewater is 1:1000, and let it stand for a week.

[0029] The biological preparation is prepared as follows:

[0030] (1) Put the corn stalks into the pulverizer and pass through a 100-mesh sieve to obtain corn stalk powder;

[0031] (2) Culture Thiobacillus ferrooxidans, Thiobacillus thiooxidans, Pseudomonas aeruginosa and Sphingomonas to a concentration of 1×10 7 cells / ml of bacterial liquid, and then mixed according to the volume ratio of 3:1:2:2 to obtain the mixed b...

Embodiment 2

[0042] The sewage treatment test of the microbial preparation prepared by the embodiment of the present invention 1:

[0043] The gray water of a power plant exceeds the index mainly due to ph, suspended solids, COD, ammonia nitrogen compounds, etc.

[0044] According to the method described in Example 1, the results of the detection and treatment of the gray water are shown in Table 1.

[0045] Table 1

[0046]

[0047] In conclusion, the treated wastewater complies with the GB / T18921-2002 urban anhydrous recycling standard, and fully meets the national first-level discharge standard

Abstract

The invention belongs to the technical field of biological environment protection and discloses a biological agent for treating ash sluicing water of a cable channel. The biological agent is prepared by culturing thiobacillus ferrooxidans, thiobacillus thiooxidans, pseudomonas aeruginosa, sphingomonas and scenedesmus obliquus and mixing with a specific carrier. The biological agent can be used for effectively treating ash sluicing waste water.

Description

technical field [0001] The invention belongs to the technical field of biological environmental protection, and in particular relates to a biological preparation for treating gray water from cable trench flushing. Background technique [0002] China's electric power is based on coal-based power generation structure, so the problem of fly ash is very prominent. As far as the national average is concerned, 250-300kg of fly ash is produced for every ton of coal burned. In the future, with the increase in the number of coal-fired power plants, the amount of ash output will also increase. A large amount of fly ash must be transferred from the power plant to the ash storage yard. It is more economical to use the hydraulic ash removal system to send the ash and slag to the ash yard. It is also the main way of ash removal in China at present. After being sent to the ash yard, the coarsely dispersed impurities in the ash slurry will settle down in the ash yard, and the clarified wa...
