With the implementation of the South-to-North water diversion project in china, water quality problems have become increasingly prominent along the Eastern Route of South-to-North Water Diversion Project, China. As an important water-transfer channel and storage lake for the Eastern Route, the water...

In this paper, the flocculant and trapping performance of the crosslinked starch-graft-polyacrylamide-co-sodium xanthate (CSAX) was evaluated using wastewater that contains Hg²+ as the target. Some factors affect the removal rate of Hg²+ were investigated. The experimental results show that the CSAX...

Blow-by of crankcase should be led into intake system and burn it again to protect environment. This study examines effect of crankcase blow-by on formation of particle. By controlling the flow of crankcase blow-by to atmosphere or intake system, number concentration of particle distribution was measured...

In order to test the effect of surface soil resources in highway construction,surface soil resource is used as the external-earth base material to conduct the external-soil spray-seeding greening test on the expressway slope. Research results show that using surface soil as main external-soil base material...

The consistency of power Li-ion batteries storage was researched at 20?and 40? environment temperatures. The results showed that the self-discharge rate of monomers of similar initial performance in storage will lead to inconsistency of monomer battery voltage after storage. That is to say, the battery...

A resource-based method for completely removal of SO₂ from flue gas by utilizing recycling manganese hydroxide (Mn(OH)₂) as an absorbant was proposed, which utilized catalytic oxidation of the manganese in the air on the oxidation of sulfur dioxide to soluble sulfate while removing impurities by filtration...

Oxy-fuel combustion is an important development direction of combustion technology, and the key technology to reduce the cost of flue gas purification is the reduction of denitration cost. Based on the experiments and simulation process with Aspen Plus of pressure denitrification process, the reaction...

High intensive shortwave light can be obtained through triboelectrification induced triboplasma discharge in sliding friction. Therefore, It will present a new method for emitting shortwave light which can be used as light source to control agricultural pests by wind-driven sliding friction without extra...

Soil aggregates content, soil organic carbon (SOC) concentration and density in soil aggregates in 0~5, 5~10, 10~20, 20~30 cm soil layers in peat mire soil in wetland, soybean and paddy field reclaimed from the wetland around Xingkai Lake were determined to investigate how reclamation of wetland for...

The dirt on the lens surface of runway lights makes the projective light darker, affecting the aircraft's taking and landing, so it needs to clean runway lights regularly. It analyzed the cleaning efficiency, cleaning effects, environmental performance and operational safety performance of several cleaning...

ZIF-8@Polyacrylate carboxyl super-macroporous microspheres was synthesized by insitu growth method with the ZIF-8 nanoparticles loaded on the surface of PC-SMM for adsorptive removal of Malachite Green (MG) from water. The as-synthesized ZIF-8@PC-SMM was characterized by SEM and XRD experiments, and...

Sludge bioflocculant was prepared from excess biological sludge by extraction method with dilute hydrochloric acid. A series of experiments were performed to investigate the flocculation efficiency of sludge bioflocculant towards starch and oily wastewater. The results indicated that the sludge bioflocculant...

In recent years, with the deepening of the green development concept and the increasingly stringent environmental regulations, how to deal with the problem of industrial waste gas has become a major challenge for industrial enterprises. This paper mainly expounds the harm of industrial waste gas, as...

Rape plant is widely distributed in China, especially in southern China such as Xinghua in Jiangsu province with abundant rape straw resource. According to the characteristics of the biomass resources in those areas, it is very suitable to replace the traditional direct incineration method by using the...
