Embodiment 1

[0032] A method for preparing a compound microbial preparation for controlling black and odorous water bodies in rivers, the steps of which are:

[0033] (1) Take willow wood and cut it into rectangular cuboids with a size of 11cm×11cm×50cm. Place the cut willow wood pieces in a sealed heating furnace and seal them for heating so that they can be heated and pyrolyzed in an oxygen-free environment. The pyrolysis temperature is 180°C , the pyrolysis time is 4 hours, and the willow block after obtaining the pyrolysis; (2) configure the mixed solution, prepare the solution according to the following components and mass percentages: 6% sodium carbonate, 3% polyurethane, 1.5% acrylamide , sodium caseinate 2%, the remainder is water; (3) the willow block after the pyrolysis in the step (1) is taken out from the stove, drops into the solution of the step (2) when the temperature is reduced to 100 DEG C ( Mainly use residual temperature adsorption to increase adsorption efficiency and ...

Embodiment 2

[0036] A method for preparing a compound microbial preparation for controlling black and odorous water bodies in rivers, the steps of which are:

[0037] (1) Take willow wood and cut it into rectangular cuboids with a size of 20cm×20cm×100cm. Place the cut willow wood pieces in a sealed heating furnace and seal them for heating so that they can be heated and pyrolyzed in an oxygen-free environment. The pyrolysis temperature is 240°C , pyrolysis time is 5 hours, obtains the willow block after pyrolysis; (2) configure mixed solution, prepare solution according to following components and mass percentage: sodium carbonate 5%, polyurethane 6%, acrylamide 0.5% , sodium caseinate 1%, surplus is water; (3) the willow block after the pyrolysis in the step (1) is taken out from the stove, drops into the solution of step (2) when temperature is reduced to 85 ℃, Soak for 20h, pull out the willow block, and dry the willow block to obtain the loaded willow block; (4) select the biogas dige...

Embodiment 3

[0040] A method for preparing a compound microbial preparation for controlling black and odorous water bodies in rivers, the steps of which are:

[0041] (1) Take the willow wood and cut it into a rectangular cuboid with a size of 3cm×5cm×30cm. Place the cut willow wood block in a sealed heating furnace for sealing and heating, so that it can be heated and pyrolyzed in an oxygen-free environment, and the pyrolysis temperature is 200°C. , the pyrolysis time is 3 hours, and the pyrolyzed willow block is obtained; (2) configure the mixed solution, and prepare the solution according to the following components and mass percentages: 7% sodium carbonate, 5% polyurethane, and 1% acrylamide , sodium caseinate 4%, surplus is water; (3) the willow block after the pyrolysis in the step (1) is taken out from the stove, drops into the solution of step (2) when temperature is reduced to 90 ℃, Soak for 30h, pull out the willow block, and dry the willow block to obtain the loaded willow block...

Abstract

The invention discloses a composite microbial preparation for controlling a black and odorous water body of rivers as well as a preparation method, application and a preparation method of the composite microbial preparation, belonging to the field of biological treatment of sewage. The preparation method of the composite microbial preparation comprises the followings steps: (1) cutting willows into cuboids; (2) preparing a mixed solution; (3) taking out pyrolyzed willow blocks in the step (1) from a furnace, adding the pyrolyzed willow blocks into the solution obtained in the step (2) before the temperature is decreased to 85 DEG C; (4) selecting a biogas digester in a pig farm, weighing biogas slurry from the biogas digester, stirring, mixing, and feeding Bacillus subtillis and Candida albicans into the biogas slurry; and (5) feeding the loaded pyrolyzed willow blocks obtained in the step (1) into the biogas slurry, so as to obtain the composite microbial preparation. The composite microbial preparation is good in stability and is capable of eliminating blackness and odor of the water body and strongly absorbing substances including hydrogen sulfide, iron, manganese sulfide and the like in sewage, the preparation work is simple, the quality of treated water completely meets the national discharge standard, and secondary pollution is avoided.

Description

technical field [0001] The invention belongs to the field of biological treatment of sewage, and in particular relates to a compound microbial preparation for treatment of black and odorous water bodies in rivers, a preparation method, an application and an application method. Background technique [0002] Landscape water bodies such as rivers are an important part of urban human settlements. However, due to their characteristics of easy pollution, small water environment capacity, and poor self-purification ability of water bodies, they can easily become the recipients of domestic sewage, rainwater, and garbage for residents, resulting in The massive consumption of dissolved oxygen in the water body has caused the water body to be in a black and odorous state due to the lack of oxygen, causing the entire ecosystem to be in crisis. Black and smelly urban rivers have become a common pollution problem in many large and medium-sized cities in my country. Black and smelly rivers...
