Abstract

The invention belongs to wastewater treatment auxiliaries and particularly relates to a bioenergy strengthening liquid agent used for wastewater deodorization and sludge reduction. The bioenergy strengthening liquid agent comprises the following raw materials in parts by weight: 2.0-2.5 parts of meadow soil, 0.5-1.0 part of marine mud soil, 0.5-1.0 part of deep river soil or humus soil, 3.0-3.5 parts of germs, 3.0-3.5 parts of humic acid, 0.1-0.2 parts of sea salt and the balance of clear water and pumice stone. The bioenergy strengthening liquid agent is simple in formula and low in cost and can realize deodorization, the raw materials are easily available, the sludge reduction is reliable, the content of COD (chemical oxygen demand), BOD (biochemical oxygen demand), SS (suspended substances) and TN (total nitrogen) is increased, and the removal rate of TP (total phosphorus) and the sludge reduction are not influenced. On one hand, hydrogen ions generated by organic matter decomposition are proactively utilized as proliferation energy by chemoautotrophic symbiotic bacteria, so that elements forming odors are lost; on the other hand, protozoon controlling bacterial increment catches and eats more bacteria for keeping balance while the types and number of bacteria are increased, so that sludge is reduced.

Description

technical field [0001] Treatment of polluted water bodies, especially for sewage deodorization and sludge reduction. Background technique [0002] Wastewater treatment usually adopts the activated sludge method, which has the advantages of low construction cost, low operating cost, and easy management. However, there are disadvantages such as the generation of foul odor, the large amount of residual sludge and the difficulty in disposal. At present, the commonly used odor treatment methods are: such as collection biological deodorization method; the principle is that the odor that has occurred is collected by physical methods and decomposed through biological filtration. The disadvantage of this method is that the treatment effect is affected by ambient temperature, air pressure, concentration, etc., and is limited to a small scale. Such as the use of biological enzyme block deodorization method; the principle is to use the action of biological enzymes to strengthen the ac...
