Problems solved by technology

[0006] The purpose of the present invention is to provide a composite agent for sewage treatment, which solves the problems of existing sewage treatment agents such as single action, inability to achieve biodegradation, easy to cause secondary pollution, and inability to realize harmless resource utilization of settled sludge. The improved composite agent can be used in combination with the drug components, and the drug components can also be used separately. It has high biodegradability, no secondary pollution, cheap and easy to buy, and the treated sewage can be directly Clean discharge or recycling, simultaneous realization of sludge reduction and resource utilization have the characteristics of economy, environmental protection, green and high efficiency, powerful functions and wide applicability

Abstract

The invention discloses a multifunctional environment-friendly sewage treatment compound agent and preparation and application methods thereof. The multifunctional environment-friendly sewage treatment compound agent is composed of two or three of the following components including, by weight part, 50-85 parts of compound flocculant, 10-35 parts of composite oxidant and 5-15 parts of complex enzymes. The multifunctional environment-friendly sewage treatment compound agent can be widely applied to sewages of different concentrations from food processing, bio-pharmacy, daily life, breeding and chemical industry to rapidly remove contained matters such as suspensions, COD (chemical oxygen demand), BOD (biological oxygen demand) and hazardous and toxic substance. The multifunctional environment-friendly sewage treatment compound agent is high in biodegradability, free from secondary pollution, low in price and easy to purchase; processed sewages can be directly cleaned and discharged or recycled to synchronously achieve reduced and recycle utilization of sludge. Therefore, the multifunctional environment-friendly sewage treatment compound agent has the advantages of being economical, environmentally friendly, green, efficient, wide in applicability and high in functionality.

Description

technical field [0001] The invention relates to a multifunctional and environment-friendly sewage treatment composite agent and its preparation and application, belonging to the field of water treatment and environmental engineering. Background technique [0002] my country's economy has developed rapidly in recent years, but at the same time it has also caused some pollution to the environment. In order to protect the ecological environment, my country actively advocates energy conservation and emission reduction, and has given enough resources in the treatment of pollutants. Pay attention to. In the situation of increasing shortage of water resources in the world, the treatment of sewage is particularly important. After the sewage is treated, it can be recycled to reduce the consumption of water resources for the production of our country. Water treatment technology uses relevant technical means to purify sewage so that it can be used continuously, so water treatment tech...
