Problems solved by technology

Activated sludge method is a widely used water treatment technology at present, but there are some problems in this method, such as the suspension concentration of the mixed liquid in the biological reaction tank should not be too high, if it is too high, it will affect the settlement effect, and it is easy to generate pollution. Swelling and stickiness of mud cause problems such as difficult dehydration and unfavorable operation

Embodiment 1

[0016] Select an appropriate amount of high-quality diatomite, crush it with a pulverizer, and screen the ore soil particles between 50-55 mesh through a screening machine, put the particles into a high-temperature furnace and burn them at a high temperature for 2.8 hours, and the temperature is controlled at about 1000°C After burning, let it cool naturally to between 85-90°C, then put it into the reaction tank, and add 0.5-0.7% Na 2 CO 3 And 10ppm microbial growth accelerator cobalt, after reacting for 4 hours, put it into the drier and process for 3 hours to be the finished product.

Embodiment 2

[0018] Select an appropriate amount of high-quality diatomite, crush it with a pulverizer, and screen the ore soil particles between 55-60 mesh through a screening machine, put the particles into a high-temperature furnace and burn them at high temperature for 3 hours, and the temperature is controlled at about 1000°C After burning, let it cool naturally to between 95-100°C, then put it into the reaction tank, and add 0.6-0.8% Na 2 CO 3 After reacting with 12ppm microbial growth accelerator cobalt oxide for 4.5 hours, it is finally put into the drier for 3.5 hours to be the finished product.

[0019] The use method of the biological filler produced by this process is similar to that of the activated sludge method, and it can be directly put into the tank. Because the filler itself has biological characteristics, it can not only promote the growth of microorganisms, but also provide a good growth place for microorganisms. It can also be adjusted according to changes in water q...

Abstract

The present invention belongs to the field of water processing biological filler preparing technology. Diatomite containing SiO2 and Al2O3 as material is processed through first crushing, sieving and high temperature activatation; then introducing microbe growth promoter and denaturation, and final drying to form the water purifying filler. The water purifying filler may be used widely for various domestic sewage and industrial effluent. Compared with available technology, the present invention has the features of easy-to-obtain material, simple preparation process, low cost, fast microbe growth, high water processing effect, etc.

Description

1. Technical field [0001] The invention relates to a production technology of water treatment filler, in particular to a preparation process of water treatment biological filler. 2. Technical background [0002] At present, in the field of water treatment biotechnology, there are mainly two water treatment technologies: activated sludge method and biofilm method. Activated sludge method is a widely used water treatment technology at present, but there are some problems in this method, such as the suspension concentration of the mixed liquid in the biological reaction tank should not be too high, if it is too high, it will affect the settlement effect, and it is easy to generate pollution. Swelling and stickiness of mud will cause problems such as difficult dehydration and unfavorable operation. The biofilm method is the biological contact oxidation method. Its basic principle is to suspend soft fillers, semi-soft fillers and plastic PVC hollow balls in water, and realize th...
