Upgrading Of Tannery Sewage Treatment Capacity And Management Level In Xinji

In recent years, with the continuous improvement of the national environmental protection policy, the tannery sewage treatment capability and management level in Xinji has been upgraded in an all-round way.

First, we must firmly grasp the construction of pollution control facilities.

The tannery area invested 38 million yuan to expand the three stage sewage treatment plant, and built a peak load sewage treatment plant, so that the daily sewage treatment capacity of the tannery area reached 45 thousand tons; the trial camping camp leather area invested about 3000000 yuan for expansion and pformation, with a daily handling capacity of 4800 tons.

At present, the tannery industry sewage treatment capacity can not only meet the full load production of existing enterprises, but also provide space for the next two years of development.

Two is to further strengthen and improve the sewage discharge management mechanism.

The drainage metering pumping station has been built for self owned well tanning enterprises, and on-line monitoring has been realized. The three party restrictive mechanism has been established, and the sewage treatment plant has been put into operation and implemented the management measures of emission permits.

Three, we have made significant breakthroughs in emission reduction and recycling.

The new technologies such as chrome tanning, vegetable tanning and combined tanning have been developed and reduced by more than 60% from the source.

The water-saving overload rotary drum installed by Dongming company can save 56% of the water consumption. The sheep skin ash free alkali expansion technology has been successfully studied. The cowhide company has realized the recycling of waste chrome liquor and ash alkali waste liquid, and sodium sulphide, lime and chrome tanning liquid save more than 30%. It provides powerful technical support and demonstration and promotion for energy saving and emission reduction.
