Comprehensive sewage purifying treatment equipment for environmental engineering

Abstract

The invention relates to comprehensive sewage purifying treatment equipment for environmental engineering. The equipment comprises a heavy metal processor, a multi-medium filter and a treatment purifier which are connected with one another integrally. The filtered outlet of the heavy metal filter is connected to a water inlet pipe of the multi-medium filter, and the discharge opening of the multi-medium filter is connected to a water inlet pipeline of the treatment purifier. The heavy metal processor has high impurity absorption efficiency, and can treat heavy metals in water through adsorption, centrifugation and electrolysis separately, so that the heavy metal sludge treatment efficiency and quality are improved effectively. The multi-medium filter has the advantages of circular filtering treatment, good filter effect and no waste of water resources and a leaker is less prone to blockage. The treatment purifier has an effect of detecting the water quality, can perform reflux treatment on sewage, and is good in sewage treatment effect.

Description

technical field [0001] The invention relates to the field of sewage treatment devices, in particular to comprehensive sewage purification treatment equipment for environmental engineering. Background technique [0002] Water is the source of life and the most precious resource in nature. The protection, utilization and treatment of water resources is one of the hottest topics in the world today. Therefore, international research on water quality and water treatment technology is developing rapidly, and pollution from industrial wastewater and domestic wastewater is also a major problem facing the country. . my country is one of the countries that lack water resources in the world. The development of water quality and water treatment technology has made great progress, and has made great contributions to environmental protection and water conservation. However, the current sewage treatment technology and development There is still a large gap between countries. At present, ...

Problems solved by technology

[0005] However, after analysis, it is found that the existing sewage purification treatment equipment has the following deficiencies: 1. The initial precipitation is not complete, and there are many impurities; 2. The adsorbed flocculant has certain toxicity, and the adsorption efficiency is low; 3. The centrifuge treatment time Long, low water purification efficiency; 4. After long-term use, the internal leaker is easily blocked by fine sand; 5. Cannot carry out reflux treatment of sewage; 6. Poor treatment effect on sewage
