Deep treatment technology for reclaimed water

Abstract

The invention discloses a deep treatment technology for reclaimed water. The method sequentially comprises the following steps that yielding water of a sewage treatment plant is firstly pumped into a BAF pool for deep biochemical treatment, enters a denitrification filter pool and then enters a nitration filter pool, and aeration treatment is performed; chemical phosphorus removal is performed on yielding water of the BAF pool; deep adsorption is performed on yielding water of a filter cloth filter through a granular activated carbon adsorption tank; yielding water of the granular activated carbon adsorption tank is pumped into a nitrate nitrogen ion exchange resin deep treatment system. Compared with the prior art, the deep treatment technology for the reclaimed water has the following advantages that the reclaimed water can stably reach the III-class water standard of surface water and is enough to serve as supplementary water of park internal lakes after being treated by adopting the deep treatment technology; the internal lakes are supplemented by the reclaimed water treated by adopting the deep treatment technology, the regional water shortage problem can be partially relieved, and the deep treatment technology is consistent with the cyclic utilization and energy conservation and environment protection policies advocated by the state; the deep treatment technology is lower in comprehensive investment and operation cost; the deep treatment technology is free of hidden dangers of secondary pollution.

Description

technical field [0001] The invention relates to a process for advanced treatment of reclaimed water. Background technique [0002] With the rapid development of my country's economic undertakings, a large number of livelihood projects have been put on the agenda. The construction of parks is closely related to the health and daily life of ordinary people, and it is even more valued by leaders at all levels. [0003] Inner lakes are generally designed in the planning and design of parks. The existence of inner lakes can "enliven" the park and increase the landscape effect. However, due to daily evaporation and infiltration, the water volume of lakes in general parks will gradually decrease. The drop in water level will lead to the bare soil of the lakeshore, affecting the landscape effect, and even the inner lake will dry up, and the entire inner lake will become a muddy pond, which will become a failure of the park landscape. Therefore, the general park needs to replenish t...

Problems solved by technology

However, the rainfall in many areas is relatively low, which is not enough to replenish the water required by the lakes in the park; in some areas, the lakes, rivers, and groundwater are insufficient, or they are far away from the target site, so it is impossible to use these supplementary methods; tap water is expensive, and many places Water resources are scarce, and there is no water to replenish
