The water level of Lake Hulun has changed dramatically in recent years. interannual interaction between groundwater and lake is an important factor affecting Hulun’s level. Vertical recharge the particularly important. Based on analysis differences hydrogeochemical quality characteristics spring water, surrounding groundwater, source mechanism vertical are determined. results show that exposed at bottom Hulun, there obvious ice thickness, ion characteristics, characteristics. For example, thickness site only 6.8% average lake, a triangular area directly above not covered by ice; contents were less than 50% those water; NH4+-N content was 3.0% mean water. In addition, total nitrogen (TN), dissolved oxygen (DO), all fall outside range groundwater. general, recharged infiltration phreatic aquifer but confined aquifer. Additionally, basin may be supplied with through basalt channels while it frozen. first deep, flowing fault zone to loose-sediment under finally interacts

Abstract Excessive phosphorus input leads to poor water quality and eutrophication. However, limited research has directly explored the influence of pH on phosphorous in actual aquatic systems. This study investigated effect removal synthetic, eutrophic, black-odorous water. The levels ranging from 3.5 12.0 were adjusted using H 2 SO 4 , NaOH, cement with a 0.5 ± 0.03 interval, followed by 25 1 °C static bath for 24 h. Results showed that NaOH-adjusted removed >65% TP eutrophic (pH ≥9.50) ≥11.0). Meanwhile, cement-adjusted >84%, >90%, >82% synthetic solution ≥11.0), ≥9.5), respectively. alkaline environment enhanced formation Ca-P water, strengthened chemical precipitation providing additional Ca 2+ . lays groundwork adjustment strategies holding significant implications resource management environmental protection.
