Problems solved by technology

This is the consequence of incomplete transformation
[0009] Due to the reproducibility of organisms, most of the replicas currently used are replicas. However, these replicas have short survival time, poor load resistance, high sewage rebound rate, low number of original bacteria, and slow reproduction. Generally, a cycle is completed in 60 days. The number is low, the medium is mainly glucose, and because the main substrate of the sludge is humus, this kind of organisms cannot degrade the sludge

Embodiment 1

[0042] Disinfect the plant straw at 20°C-75°C, dry it, domesticate the bell worms under the required purified water quality to adapt to the temperature of -10-40°C, obtain the bacterial liquid, and then use the bacterial liquid as the bacterial liquid The plant straw is sprayed on the plant straw at a weight ratio of 1:0.5, and then the plant straw is pulverized and sealed and packaged at a temperature of 20°C to 35°C.

Embodiment 2

[0044] Disinfect the plant stalks at a temperature of 20°C to 75°C, dry them, put the bellworms and rotifers into the water that needs to be purified, cultivate them for screening and domestication, and make them adapt to the temperature of -10°C to 40°C to obtain the bacterial liquid, and Subsequently, the bacterial liquid is sprayed onto the straw at a weight ratio of the bacterial liquid to the plant straw of 1:0.1, and then the plant straw is pulverized and sealed and packaged at a temperature of 30° C. to 40° C.

Embodiment 3

[0046] Disinfect the plant stalks at a temperature of 20°C to 75°C, dry them, put the rotifers into the water to be purified for screening and domestication, and make them adapt to the temperature of -10°C to 40°C to obtain the bacterial liquid, and then the bacterial The liquid is sprayed on the plant stalks with the weight ratio of the bacterial liquid and the plant stalks being 1:0.22, and then the plant stalks are pulverized and sealed and packaged at a temperature of 15°C to 20°C.

Abstract

The invention discloses a preparation of biological self-purification sewage sludge. The preparation is powder prepared by spraying acclimated microbes on plant straws serving as a carrier. The powder is suitable for remediating static water and dynamic water. The invention also provides a method for preparing the preparation and application of the preparation.

Description

technical field [0001] The invention belongs to the technical field of environmental protection. Specifically, the invention relates to a preparation of biologically purified sewage sludge, a preparation method thereof and an application thereof. Background technique [0002] With the development of world industrial production and the increase of population, the discharge of industrial wastewater and domestic sewage is increasing day by day. According to statistics, in 2007, my country's sewage discharge has reached 55.67 billion tons. [0003] Most of the existing sewage treatment plants adopt the activated sludge method, which utilizes the metabolism of microorganisms in the activated sludge to make the activated sludge have the vitality of converting organic pollutants into stable inorganic substances. The organic matter is oxidized and decomposed into inorganic matter, so as to achieve the purpose of purifying wastewater. Due to the characteristics of biological sludge...
